Friends of the Earth Melbourne (March 2012) Draft

Survey of Pesticides in Surface Waters of Domestic Water Supplies – Victorian Water Authorities 1998* - 2017 (plus including additional data to July 2017).

(page currently being updated from October 2008 report)

(*average date)

Since 2008 there have been well over 200* positive pesticide detections in the Upper Yarra Catchment. Sugarloaf Reservoir was never designed to filter out pesticides. The Yarra catchment is not a gazetted domestic water supply even though it supplies drinking water to 27% of Victoria's population. See here for more information.

*The true amount is probably over 900 detections in water and sediment, however this information has never been released publicly and the only report containing this information included data referring to locations outside of the Upper Yarra catchment, with exact locations remaining unpublished.

1. Summary

There is little monitoring of agrochemicals in surface waters in Victoria. Water authorities have the best set of information in Victoria about pesticides in drinking water, but in many cases even this is most likely woefully inadequate. Between 2006 and 2007, Friends of the Earth, through Freedom of Information requests, gained access to some of the records of the State's Water Authorities mainly covering the years 1998-2007, and was surprised at the lack of information supplied by authorities. [This information has been sporadically updated by Friends of the Earth since 2008. The most significant change has been a new testing regime by Melbourne Water (reduced back to <30 pesticides in 2013) in the Yarra River near the offtake to Sugarloaf Reservoir, testing of the upper Yarra catchment by a scientific team including members of Melbourne Water, DPI and RMIT, continued monitoring by Barwon Water and a new water monitoring group called CAPIM, based in Melbourne University. Over 900 pesticide detections were found in the Port Phillip region in 2008/9 alone!. The 2011 version of the Australian Drinking Water Guidelines significantly expanded the amount of guidelines for pesticides in relation to the 2004 version which was used in the 2008 FoE report].

A view of Kerang looking south. The highest pesticide reading in a domestic water supply in Victoria between 1998-2011 was recorded in Channel 14/2 which supplies Kerang with drinking water in October 2005 - Esfenvalerate at 65ug/L or 2 times over the level set in the 2011 Australian Drinking Water Guidelines. Esfenvalerate, an insecticide, is registered in Australia for use on various crops including cereals, pulses, legumes and pastures. Worryingly, the insecticides Bifenthrin 100ug/L and Taufluvalinate 75ug/L were also detected at the same time. No guideline levels exist for Bifenthrin and Taufluvalinate.

Pesticides detected in Victorian domestic water supplies included; Esfenvalerate, 2,4-D, Fipronil, Pirimicarb, Methiocarb, Glyphosate, Hexazinone, Simazine, MCPA Chlorpyrifos, Atrazine, Iprodione, Dimethoate, Chlorpyrifos, Fenarimol, Carbaryl, Metolachlor, Trichlorfon, Triclopyr, Triadimfeon, Pendimethalin, Bifenthrin, Taufluvalinate, Hexachlorobenzene, DEET, numerous fungicides in the Yarra catchment and the organochlorines Hexachlorobenzene, Pentachlorophenol, Diedrin/Aldrin, Heptachlor, Methoxychlor, Lindane and Endosulphan. Some of the most serious incidents appear to be mostly related to use of 2,4-D, which is classified by the IARC (International Agency for Research on Cancer) as a Class 2B carcinogen - possibly carcinogenic to humans. 2,4-D is also known as an endocrine disruptor. Many of the organochlorines had been banned for some time yet residues remain in sediment, which can be mobilised during rainfall. (Most of the pesticides detected are known endocrine disruptors). The high reading for pyrethroid insecticide and suspected endocrine disruptor Esfenvalerate in 2005 is also of concern.

Three* pesticide pollution incidents were reported above the 2011 Australian Drinking Water Health values (*The incident concerning simazine on the Sunday Creek occurred 50km upstream from the nearest town offtake and was 'apparently mostly' contained by a farm dam). The most at risk water supplies, according to the limited FoI information, appear to be the Sugarloaf Reservoir catchment (Upper Yarra) managed by Melbourne Water and the two open aquaduct systems which flow into the Wurdee Boluc Reservoir and into the Stony Creek Reservoirs managed by Barwon Water. The Yarra is at risk from horticultural fungicides, insecticides and herbicides. The Geelong aquaducts are at risk from cropping and grazing pesticides as the aquaducts flow through open farmland, in some places lower than surrounding farmland. The Broken Creek system managed by Goulburn Murray Water, which supplies the communities of Nathatalia and Numurkah also appears to be at some risk as do some communities relying on channel water in northern Victoria. The longest duration pollution incident reported in the past decade occurred in the Moorabool System (Barwon Water) with the herbicide Hexazinone, associated with weed control in pine plantations, leaching at low volumes for almost 3 years. The pesticide was detected 50km downstream.

Many more questions remain about the quality of drinking water in terms of pesticide pollution. In mid 2007 four water authorities (28.6%) were not testing for pesticides at all (that number is now two). Seven water authorities (50%) were testing on average only two currently used pesticides, leaving only three (21.4%) water authorities testing for between 40-72 pesticides. This means that in late 2007, eleven (78.6%)of the fourteen water authorities were testing for less than 2 currently used pesticides. This is most unsatisfactory.

To put this into context, Friends of the Earth estimates that between 200-300 pesticides are used in Melbourne's water supply above Sugarloaf Reservoir which is dominated by vineyards, orchards, berry farms etc. Melbourne Water only significantly increased their testing in the Yarra catchment in 2010, with next to no pesticide testing occurring for 30 years. An unpublished report taken from samples taken in the Port Phillip region between 2008/9 revealed the detection of over 500 pesticide samples in water, over 260 in sediment and over 140 in passive samplers. The Maffra/Stratford water supply in Gippsland is dominated by irrigated pasture. Much of Ballarat's water supply is dominated by potato farms and plantations. The water authority in the Ballarat region Central Highands Water uses Hexazinone in their plantations many of which surround reservoirs, yet does not test for it or many other pesticides widely used by the potato industry. These examples are not uncommon which means that many water supplies may be at risk but no data is available to determine if pesticides are leaching into these water supplies.

The three most commonly used pesticides used in Australia, Glyphosate, Atrazine and Simazine remain under-sampled across Victorian water supplies. In 2008, 4/14 authorities test for Glyphosate, 5/14 test for Atrazine and 1?/14 test for Simazine, even though Simazine is registered for use across a plethora and land uses. Friends of the Earth estimates that over 200 'commonly used' pesticides in Victoria remain untested by any water authority, whilst approximately only 70 are tested by at least one water authority. This means that the 140 positive pesticide results recorded in this survey are likely to represent a tiny fraction of the total range of pesticides that could be in the water, particularly in times of heavy rainfall after spraying events. It should also be stated that most of the pesticide testing reviewed in this project has been conducted during a ten year 'dry spell' which may well have influenced overall results to a certain extent.

2. Recommendations

1) Water authorities must undertake detailed catchment surveys to determine which pesticides are being used in what volumes in different parts of their catchments to aid in the design of more effective monitoring programs. Catchment protection should be a priority including multiple barriers to prevent pest and toxic chemicals getting into waterways. Rapid implementation of water protection policies also needs to occur.

2) Water authorities must be transparent and accountable in relation to pesticide monitoring in water supplies. The number of pesticides tested and the frequency of testing needs to be reviewed to ensure the programs are relevant and measuring currently used pesticides. Monitoring data must be available to the public.

3) A list of Restricted Use "Water Supply" pesticides must be determined by the Department of Primary Industries, after public consultation, and circulated to all pesticide users operating within domestic water supply catchments. This could be regarded as an extension of the current 'restricted use' provisions already in operation. If restricted pesticides continue to be detected they should be banned from use in water supply catchments.

4) The pesticide control of use legislation must be amended to require commercial users of pesticides operating in domestic water supplies, to maintain records of pesticide use for an indefinite period. Copies of pesticide records should be made available to water authorities and the DPI.

5) Postive pesticide detections must be followed up with an investigation by water authorities and/or the DPI to determine the source of pesticide contamination. Remedial action must be taken to stop the source of pesticide contamination entering waterways. Postive pesticide results, at any level, mustbe made public by water authorities.

6) Water authorities managing high risk catchments should invest in water treatment facilities which incorporate the use of treatments to remove pesticide residues, such as carbon filters and/or reverse osmosis filtration.

7) There are no government agencies responsible for monitoring pesticide usage data in Australia. This situation requires urgent attention.

13.1 Pesticides Tested for by Water Authorities in Victoria

February 2008: Woori Yallock Creek. Strawberry pesticide spraying in Melbourne's water supply. Pesticides used on strawberries and many other agricultural practices are not tested for by Melbourne Water.

3. Background

During the 1970's and 1980's Friends of the Earth in Melbourne was very active on pesticide issues. Emphasis on pesticide issues within the Friends of the Earth network in the 1990's 'centred' on Tasmania, particularly in regards to the misuse of Atrazine in forest plantations. For a number of years however members of Friends of the Earth Melbourne’s Forest Collective, (The Forest Network 1993-2004) became increasingly concerned about the use of agrochemicals in the plantation forestry industry. Friends of the Earth was concerned that many plantations (particularly pine) were grown in high rainfall areas of Victoria and in areas that may be used for domestic water supplies.

A list of pollution incidents concerning plantations was compiled by FoE highlighting the fact that pollution events had occurred, but these had largely been confined to Tasmania and South Australia. Very little information was available regarding incidents in Victoria and the privatisation of the States plantation base in 1998 (sold to Hancock Victorian Plantations), meant that plantation forestry was exempt from Freedom of Information requests and therefore ‘beyond the public gaze’. It was also evident that plantation forestry was booming throughout the state. What was the impact of the plantation expansion on the state's water supplies?

In early 2002 and 2003 Friends of the Earth sent out Freedom of Information (FoI) requests to the Gippsland EPA and Gippsland Water, requesting information about positive pesticide detections in Gippsland catchments and catchments that supplied residents in the region with drinking water. FoE had long been involved in monitoring logging operations in the privatised Strzelecki Ranges. FoE had also heard rumours of pesticide pollution in the Strzeleckis, but was unsure where these events had been documented.

Limited information came from the FoI requests except for the acknowledgement that the pine herbicide Hexazinone had leached from a Hancock plantation (at Lecki) in 1998 above Australian Drinking Water Guidelines (ADWG) guideline levels and that Simazine had leaked in a pollution incident, outside of a domestic water supply. It was a shock to learn that testing for pesticides was not taking place by Gippsland Water, they were actually relying on information to be sent to them. Was this also the case with all Victorian water authorities?

North East Water had been contacted by FoE in early 2003 concerning the water supplies for Beechworth and Yackandandah. FoE was sent a list of pesticides and other pollutants stating what North East Water was sampling for. The authority was not testing for plantation herbicides even though Yackandandah has a water supply dominated by pine plantations that were being clearfelled and sprayed with herbicides.

Friends of the Earth began mapping the state’s plantation base in 2001, not only as a means of locating plantations, but also as a means of determining which plantations were located in which domestic water supplies. This information was not added to GIS programmes until early 2007 after grants from the Reichstein and Fouress Foundations. For maps see here.

By and large it was found that new bluegum plantations were being grown outside of domestic water supplies. There are notable exceptions to this trend; Midways in the Otways establishing bluegums and replanting pines with bluegums (water supply for SW Victoria), Harris Daishowa '02 in the Rocky River (Orbost water supply), Great Southern Plantations catchments in Gippsland (Meeniyan 06, Boolara 06, Foster Jan 08), Enviroinvest (Stawell Dec 07) and Woolybutt/Rimbunan Hijau Candowie Reservoir (Phillip Island Apr 08). These incursions appeared initially to be minor in comparison to existing pine plantations located in water supplies, particularly those owned by Hancock Victorian Plantations throughout Victoria and Midway Plantations Pty Ltd in the Otways.

In May 2006 Friends of the Earth and the Otways Conservation Council organized a forum at Gellibrand in the Otway Ranges. From FoE’s existing plantation mapping of the region, it became clear that the water supply with the most plantations located in it in Victoria, was probably the Gellibrand River For Otways maps see here.

The Gellibrand River is the main source of water in south west Victoria, providing drinking water to over 50,000 people. The Otway's largest plantation managers, Midway Plantations Pty Ltd, were establishing new hardwood plantations in the region and replanting pine plantations with bluegum. Bluegum expansion raised the scenario of increased spray regimes and aerial spraying of insecticides. The township of Gellibrand also had plantations within one kilometre of its offtake on Lardners Creek. A representative from South West Water also attended the meeting and provided a list of pesticides that South West Water test for. People attending the meeting were more than alarmed to learn that none of the pesticides used in plantations in the Otways were currently being tested for by the water authority.

In the second half of 2006 Friends of the Earth became aware of a pollution incident at a Hancock pine plantation at Korweinguboora, located south of Daylesford. Since 2002, the plantation had been an issue of concern for Friends of the Earth as 1400ha of the plantation surrounds Korweinguboora Reservoir, which is part of Geelong’s water supply. The Geelong water supply is managed by Barwon Water. Incidentally in a meeting held with Barwon Water, earlier in 2006, Barwon Water had stated that pesticides were regarded as a low risk.

Friends of the Earth conducted a Freedom of Information request with Barwon Water asking for details of positive pesticide readings. The response showed that unlike Gippsland Water, Barwon Water had a more rigorous pesticide monitoring system, however the FoI also revealed that not only had the Barwon system been threatened by the herbicide hexazinone which had first been detected in December 2004, but more serious incidents had occurred a few years earlier with the herbicide 2,4-D (2,4-D is registered for use in plantations but is mainly associated with grazing and cropping).

In 2006/7, the Victorian State Government reviewed the existing Agricultural and Veterinary Chemicals Act, the legislation responsible for pesticide use in Victoria. Two submissions were sent into this review by two water authorities. FoE managed to get a copy of the Gippsland Water submission which contained some serious statements including; “Records are kept for the application of restricted chemical products, but not for the other commonly used products that have environmental or health implications. Gippsland Water has had difficulty in obtaining information on the chemicals used within a catchment area upstream of a water treatment plant and town water supply… Currently there is no common record of chemical products that are likely to be applied in agricultural areas within potable water catchments…”

After more research into the location of domestic water supplies in Victoria, it became evident that plantation forestry was not the major user of pesticides in all Victorian water supply catchments. Agricultural practices in many catchments were the dominant users of pesticides. The best opportunity then to determine whether pesticides were being detected in these water supplies lay with the water authorites. What this meant is that Forest Network, which had evolved into FoE’s Land and Water Collective, would have to broaden its focus to include agricultural practices and its impacts on water quality.

It soon became clear that to get a clearer picture of what was going on where, FoE would have to start writing FoI requests to all of the States water authorities. At this time, 2006, there were also widespread concerns in regards to an EPA investigation into fish kills associated with the herbicide acrolein by Goulburn Murray Water (GMW). Not only was the authority using acrolein to kill aquatic weeds in irrigation channels and drains throughout northern Victoria, but GMW were also using the herbicides 2,4-D, amitrole and glyphosate. see GMW here . The region was also heavily impacted by thousands of hectares of horticultural and irrigated pasture.

Certain towns in northern Victoria are reliant on channels to provide them with drinking water and a report published by GMW in June 2006 (20) revealed that some of these channels had already been recording low levels of Atrazine, Endosulfan and Chlorpyrifos in town supplies. With the use of herbicides in channels for weed control, what was the risk to consumers of the drinking water? Information also came to hand (January 2008) that GMW also 'regularly' use Weedmaster (Glyphosate) in the Waranga Western Channel (WWC) as a means of controlling weeds. WWC is used as a domestic water supply and will soon be supplying Bendigo and Ballarat via a pipeline being built from Colbinabbin. Some the channels already recording low levels of pesticides can feed into, at certain times of the year, into the WWC. Grampians Wimmera Mallee Water have also stated that they use Glyphosate to control weeds in their channel infrastructure. In the past farmers have been documented using triazines (atrazine, simazine) and amitrole to control weeds along channels and drains (21). Grampian Wimmera Mallee Water do not test for these pesticides.

Tatura Water Supply Channel No.3/5. Low levels of Atrazine and Endosulfan have been detected in this channel.

In mid 2007 Friends of the Earth also began taking a closer look at the Yarra River catchment, upstream of the offtake to Sugarloaf Reservoir. Over 9000 hectares of intensive horticulture occurs in this catchment, within 20km of Sugarloaf Reservoir. This makes one source of Melbourne's drinking water (Sugarloaf Reservoir), supplying 1.2 million residents possibly the highest risk catchment in the state in terms of pesticide pollution of drinking water. See here for more details. Information also sourced from the EPA showed almost no information from that authority regarding pesticides used in the Upper Yarra catchment.

An additional FoI was sent to Barwon Water in July 2008, with results being sent back to FoE in September 2008. An additional 27 incidents were detected by Barwon Water during this time period.

In hindsight, all of the FoI requests should have been sent at the same time, this would have provided a more manageable means of standardising the information. However as the process was also a means of discovery, with snippets of information coming to light over the passage of time, a strategic co-ordinated approach to the requests did not occur. The requests were in fact staggered mainly between July 06 and January 08 and in some cases requests had to be followed with other requests after initial information was not properly requested or gained. Ideally the FoI requests should have gone back to 1977 (the start of the FoI act) but this was deemed as unrealistic by many of the water authorities who had in some cases amalgamated and who claimed that they did not have the resources, time or inclination to get access to that information.

The information is weakened further by many water authorities not testing for a suite of the hundreds of pesticides that are registered for use in Victoria. Furthermore, testing regimes may only occur on an annual, half yearly or quarterly basis, potentially meaning that a pesticide may be leaching into a water supply, but is not being picked up by the authorities. From research conducted by FoE as part of this project, it would appear that between 200-300 agricultural pesticides are used within Victorian domestic water supplies. Approximately 70% of these pesticides are not tested for by any Victorian water authority.

4. Other Surveys (1962-2007)

The State Rivers & Water Supply Commission started testing for Amitrole since approximately 1962 as it was used extensively in throughout irrigation areas throughout the state as a means of controlling water couchgrass in drians and channels.Excessively high levels were recorded in the Murray River at Swan Hill in 1972 and Broken Creek in 1972. Broken Creek is a domestic water supply for Nathalia, Numurkah and Wunghnu and the Murray River is the drinking water supply for Swan Hill.

According to the State Rivers and Water Supply Commission in a letter to the Pesticides Review Committee 1/12/66 ""(a) no pesticide analyses are required of our department by statute. (b) Most analyses will be required in connection with stream sampling. At present only amitrole is routinely sought, but there could be some interest in diuron and dalapon in the future... (c) Total analyses last year - 47 samples of water tested for amitrole..."

State Rivers and Water Supply Commission samples were taken at weekly intervals at Swan Hill in the Murray River, and at the outfall of the Deakin Main Drain at Echuca, the major outfall of the Tongala District, which has been the largest user of amino-triazole (amitrole). Samples have also been taken from other localities, in drains or streams depending on local usage of Weedazol... (Source 10/2/69 SRWSC to PRC)

1961: In the period 14/3/61 - 23/3/61 various formulations (Weedazol 50, Weedazole Total, Weedazol T1) were applied to water couch in 12 miles of drains at Tongala and 77 samples were taken from the drains to indicate the pattern and extent of contamination...Sampling at the outfall of this system gave a maximum of 0.70ppm but a more representative figure would be 0.30ppm.... Samples taken 100 yards of operating spray teams showed levels in the range of 0 - 19.5 ppm. The average contamination level was 0.25ppm representing 20% of applied material....

1963: Over the period 16/1/63 - 1/4/63, 17 samples were taken for analysis from the Tongala drain outfall, and 25 samples from the Murray at Swan Hill...Only the control samples gave positive results. These were within 10% of the anticipated value. These samples also indicated the stability of amitrole in water over, at least a 3 week period...

Positive detections 1964/5 Deakin Drain 0.1ppm, 1965/66 Bendigo Trust Channel 0.05ppm, 1966/7 Warren's Extension Bendigo Trust System 0.1 & 0.08ppm)

"Each year since 1963 samples of water have been analysed for amitrole. In 1963 and 1964 analyses were also carried out for Monuron". Sub Committee on Monitoring of Pesticide Residues Report No.2 (4/10/71?)

In 1968 the SRWSC also became concerned regarding reports that Paraquat (marketed by Imperial Chemical Industries as Gramoxone - also promoted by ICI) was being used in streams to control Cumbungi. Possibly 100 gallons per year was used in the Kerang region, 400 gallons used at Nathalia with 5% on cumbungi in channels and drains and the rest on pasture. In a letter from the Vermin and Noxious Weeds Control Authority May 24 1968 to the PRC "It is clear that with the use of paraquat for cumbungi control, some of the chemical will be entering water systems which could eventually be used for human consumption. The future use of paraquat is likely to increase and, consequently, any possible problem with contamination is likely to be greater over the next few years...My Board is aware that the oral L.D.50 value (rats) for paraquat is 157 mg/Kg body weight which makes it one of the most toxic of the herbicides in general use..."

"On October 8th 1968, the Pesticides Review Committee wrote to the Premier pointing out that in its opinion a minimum essential program for monitoring the pesticide content of foodstuffs, water, wildlife, soils and human beings in Victoria would be desirable... Only two Departments, Agriculture and Health are equipped at present to carry out analyses which would be required in a monitoring programme envisaged by the Committee". (Pesticide Review Committee 26th meeting 30/5/69).

"... to advise you that the Borad does not possess the equipment necessary to determine pesticides in water neither has it any staff trained in the necessary skills... However, it seems desirable that the Yarra River at Warrandyte should be sampled and tested for pesticide contamination in view of the possible future use of this water for Melbourne's water supply..." (MMBW to R.J.Hames Minister for Local Government 29/11/68)

On 27/6/71 US registration of amitrole for crop use was cancelled by the EPA... Use of amitrole by the Commission was approved by the Indepartmental Committee on Pesticides September 24 1962, provided a concentration of 0.3ppm in drinking water was not exceeded. In practice, the concentration in drains may be of this order, but the level in streams would not exceed 0.002ppm. About 2000lbs is used annually, mostly for control of couchgrass in drains...

During the 10 years that amitrole has been used by the SRWSC water samples have been taken from streams and drains and these have been analysed for amitrole residues by Unisearch Limited Sydney. Up to 1970/71 the limits of analytical determination was 0.03ppm but since then the limit was decreased to 0.008ppm. During this period 297 samples have been taken from rivers, drains & streams. Only five samples were found to give a positive reaction and in these cases the concentration ranged from 0.03ppm to 0.1ppm. However each of these were special cases in which contaminated channel water was diverted into creeks or drains. The procedure has now been modified so that water is utilised on pasture and is not allowed to contaminate drainage systems.

"In Victoria no information is available on contamination of water supplies although fish mortalities from time to time in some streams are an indication that some pesticides from farms lands are getting into water which may be drawn off for town supply..." Commission of Enquiry Into Effects Of Pesticides - February 1966.

"In 1971/2, this Department conducted a pesticide survey of the Ovens River catchment which was chosen because of reported heavy use of pesticides on the tobacco crops in that area..." (Commission of Public Health 6 February 1976). For results see here: 9.11 North East Water

"... It is recommended that, as an initial step, samples be taken at least four times per year from the Thompson River above Sale, the Goulburn River above Echuca, the Ovens River at Wangaratta, the Narrcan Creek at Moe, the Murray River at Swan Hill, the Silvan Dam, the South Morang Storage and Junction Basin". Subcommittee on Monitoring of Pesticide Residues. Report No.3 - April 1972

"Mr ... spoke on the part that the EPA was prepared to take in supporting a monitoring program within the state. He said he had spoken with EPA and at this stage EPA was only able to engage in activities in two areas namely the Metropolitan area of Melbourne and the Ovens Valley but was prepared to provide $2000 to support the purchase of special sampling equipment..." (Pesticides Review Committee Minutes 23/3/73)

"The Australian Water Resources Council initiated the Victorian Water Quality Assesment Program (WQAP) in 1975 as part of its National Water Quality Assessment Program. Subsequent to this, the Victorian Water Quality Monitoring Network (VWQMN) was established to collect water quality data for all major streams and their tributaries in Victoria. From 1975 to 1991, the VWQMN was re-defined through a number of reviews)" (12) These programs were however not set up to monitor pesticides.

In the Yarra catchment Melbourne Metropolitan Board of Works (MMBW) started testing for pesticides in 1977, as the Sugarloaf Reservoir was on the drawing board. Sugarloaf, later built in the early 1980's would pump water from the Yarra River which also was intensively farmed.. "In 1977 the Water Water Supply Planning Branch purchased five automatic samplers of which four were Manning S-4040 automatic samplers and one Manning S-4040T automatic sampler. The S4040T sampler was used at Yering to monitor the effects of farming and intensive cropping and the use of pesticides, soil additives etc" (32). No details of pesticide results were published and none were published in Summary Statistics from the Intensive Water Quality Monitoring Program (1978 to 1983)..

In 1978 a water quality monitoring programe was established between three states and the Commonwealth for the Murray River, however pesticide testing results remain obscured: "In accordance with an agreement between the Prime Minister and the Premiers of New South Wales, Victoria and South Australia, the River Murray Commission has recently instituted a water quality monitoring programme along the River Murray" (8 September 1978 Author?) "... The group considered that at present there were no signs that high levels of heavy metals or pesticides were affecting the river environment. However, it considered that a check should be instigated, using biological indicators, to confirm this opinion and monitor the effects of future levels of heavy metals and pesticides". (19 April 1978 Author?)

In 1978 a Cluster of birth abnormalities occurred at Yarram in Victoria (1975-76). A Report entitled "Consultative Council on Congenital Abnormalities in the Yarram District. Victorian Government. October 1978" was produced which investigated the link to the birth abnormalities and the use of 2,4,5-T in weed control (blackberry) and pine plantation establishment. It was criticised shortly after its completion for being 'statistically questionable' .

By 1979, the State Rivers and Water Supply Commission wrote to the Director-General of Agriculture in regards to their sampling programe which included: 100 samples per year under the Australian Water Resources Council Water Quality Assessment Programe - Victorian Network, 25 samples Water Commission (under EPA delegated pollution control activities and 25 Miscellaneous samples. The Commission was in favor of a centralised pesticide residue laboratory and had transferred a gas chromatograph to the Division of Agricultural Chemistry some years earlier.

November 1980 was the date of the commissioning of Sugarloaf Reservoir, sourcing drinking water directly from the Yarra River.

In 1982, the EPA published a report looking at pesticide levels in sediment and water in the Yarra River catchment, Werribee and Little River catchments (1). Positive detections for organochlorines were detected at all sites, including seven sites in the Yarra Catchment, including one site on the Yarra River, just downstream of the location of the future Sugarloaf Reservoir. The report proved that low levels of organochlorines were being washed down the Yarra catchment, which in future years would be added to the Melbourne water supply system. The report mainly focused on organochlorines.

In 1982 a further study into Macroinvertebrates of the Yarra River; stated in regards to Wandin Yallock Creek that "pesticides appear to be the most likely toxic influence at this site. TDE, DDE, DDT and Dieldrin have been detected in the sediments at a site 2km downstream of a major market gardening and horticultural area, and DDT and Dieldrin have been found in the sediments of a site in the middle of the market gardening area...TDE, DDE, DDT and Dieldrin have been detected in sediment samples 8km downstream of areas of intensive market gardening and potato growing..."

"From time to time, the Department of Agriculture carries out pesticide residue analysis and analysis of other samples for the Commission" May 5 1982 Letter Agriculture Victoria Division of Agricultural Chemistry to SRWSC.

In June 1982, according to the State Rivers and Water Supply Commission, "Over the years there have been a number of [water] samples submitted for analysis, these have arisen from the Commission's function as a delegated agency of the EPA and concern about possible contamination of water supplies. Following a recent incident where, ... the presence of pesticide residues were demonstrated in fish killed in a water supply storage, there may be an increase in requests for analysis of fish tissues where pesticide involvement is suspected. Analyses of water samples rarely show the presence of pesticides as contaminated water is usually diluted or passed downstream before samples are taken. However the total number of samples arising from all these sources would be no more than twenty in one year. For some years it has been intended that pesticide analysis should be undertaken in association with the National Water Resources Assessment Programme, there would be about 100 in number probably over one year. However due to staff shortages and lack of funding it is unlikely that this work will commence in next 12 months..." (June 2 1982 Letter SRWSC to Division of Agricultural Chemistry.

Another study (31) published in 1983 looked at pesticide transport in three sub catchments of the Upper Yarra Catchment. The pesticides Diedrin, DDT, DDE, Linuron and 2,4,5-T were detected. Pesticides at one location were most frequently detected in flows during vegetable washing operations. Pesticide concentrations were also generally higher in storm flow samples. Pesticide loads transported from catchments were generally between 1.3 and 9.3 mg/ha and between 134 and 228mg/ha in relation to vegetable washing plants. The authors wrote; "The concentrations of Dieldrin and DDT do not appear to present problems for drinking water supply in the Yarra River itself although, on occassions the concentrations detected in flows from cultivated land during storms and operation of vegetable washing plants exceeded health criteria".(31).

It could be argued that if vineyards are included, the current amount of intensively sprayed agriculture in the Upper Yarra Catchment is in 2008, 9000ha+, a 1000% increase on the 870ha intensive cropping figure quoted in the above study, potentially meaning higher pesticide volumes at a catchment level, also potentially meaning higher levels of pesticide loads transported from catchments, depending on the pesticide and site conditions.

In 1985 the Rural Water Commission of Victoria wrote; "A commitment to pesticide and herbicide analyses by the State Water Laboratory (SWL) cannot be justified at present" (2). They added; "Experience obtained in the past suggests that pesticide and herbicide contamination of the water column is unlikely following pollution incidents. Rather, these organic compounds are readily absorbed onto sediments or particulate matter and tend to be concentrated through the food chain. Analyses of sediments and biota are generally preferable in that they represent a time-weighted average of concentrations in the water, whereas grab samples of water only represent instantaneous values."(2)

"... I also confirm my verbal advice in that very little work is passed onto other laboratories... The only situations are:

-determination of organic contaminants, particularly pesticides. The laboratory is occassionally requested to determine the amounts of pesticides or similar organic pollutants in water. This work is passed to the State Chemistry Laboratory. The amount of work is very small, usually up to twenty samples per year... - salmonella are isolated from water supplies, confirmation work is done by the Melbourne diagnostic unit..." (Rural Water Commission Environment Science Branch to Public Sevice Board 16/1/87)

Another statemement by the Rural Water Commission in 1988: "As a matter of policy, the State Water Laboratory has not been involved in the analysis of pesticides or other related chemicals in water. This work is carried out by the State Chemistry Laboratory which has developed the necessary expertise and resources... A few monitoring programs that have been carried out relate to agricultural runoff and have been conducted by agencies such as the Land Protection Division of Conservation Forests and Lands, or DARA... Also some work has been performed by the South Australian Water laboratory on behalf of the Murray Darling Basin Commission..." (RWC letter 14/7/88)

This appeared to be the state of play until the 1990's.

"The true extent of pesticide exposure through polluted water supplies is not known in Australia, and governments are extremely slow to respond. In 1993, a joint NHMRC/Australian Water Resources Commission working party was still revising pesticide water residue levels, a process begun prior to the 1989 Senate enquiry. Their tardiness to recommend more stringent guidelines may well be due to the implications such changes will have for local water supply authorities. Most are already aware that many rural water supplies are contaminated with pesticides, and the introduction of new guidelines may render many supplies unfit for human consumption. Perhaps this is why the Victorian Government went cool on the issue after an initial report boldly acknowledged that a proportion of Victoria's country towns' water supplies did not neet minimum standards for safe drinking water as set by the World Health Organisation. 'With few exceptions the water quality of urban supplies outside Melbourne with respect to pesticides, herbicides and heavy metals is essentially unknown, as no routine monitoring for these compounds is currently undertaken" (17)

"By 1991, the emphasis had changed and the same government concluded that 'no significant concentrations [of pesticides] have been found'. However, as the report itself indicated, only OC pesticides were tested for ... Moreover because it used National Health Medical Research Council Guideline Values, the report was also able to claim 'no significant concentrations', even though their own results suggested the need for greater scrutiny of raw data, particularly the peaks in contamination that would 'iron out' when averages were calculated. Dieldrin values for tap water averages, for example, were only one third under the WHO Guideline Values, and the possibility of far greater concentrations occurring in particular community water supplies cannot be excluded" (17)

During the 1980's, 1990's research was also conducted into pesticide pollution of the Ovens and King Rivers. Concerns focused on the impacts of the tobacco industry. Organochlorines were detected upstream of the water supply for Wangaratta. (3) (4)

"I kept on making enquiries and found that those drinking water from Boggy Creek and the King River in most cases suffered disease and ill-health. Wangaratta's water supply is drawn from the King and Ovens Rivers, both of which have a catchment along kilometres of farms growing tobacco, hops, grapes and fruit. In many cases the crops are grown to the actual river itself and often steeply sloping to the water. There are also dairy and cattle farms to the north-east which have been quarantined because of high chemical residues. For many years, tests carried out by bodies such as the EPA, State Forests and Lands and the Rural Water Commission have shown fluctuating levels of cyclodienes in the Ovens and King Rivers but the all clear signal has been given time and time again (Shirley Barber, The Mohyu Valley, Victoria. May 1991. (17)

By 1991 the position of the SWL had changed to; "The SWL has only recently acquired the necessary analytical equipment to test for pesticides in town water supplies. This equipment has been used to 'screen' routine samples and build up a data base of information over time. Where is it suspected that pesticides may be present (such as after aerial spraying on forests or crops) the Environment Protection Agency have carried out more extensive tests to investigate the situation. Recent examples of such investigations are at Aireys Inlet and the Ovens River near Myrtleford." (5) "Analyses for the following organochlorine pesticides are being carried out by the SWL to a detection limit of one tenth of the guideline value set by the World Health Organisation in 1984: Chlordane (total isomers), DDT (total isomers), Heptachlor and Hepatachlor Epoxide, Hexachlorobenzene, Methoxychlor, Gamma - HCH (Lindane). Samples have been collected from most raw water supplies to towns throughout the state. At this stage, no significant concentrations have been found." (5).

“The only incident in which concentrations were found exceeding WHO guidelines (detection limits are generally less than 1/10th of the guideline values) was in the Colac Supply in January 1994. Samples from Olangolah Dam and the No 4 Service Basin were found to contain DDT at concentrations twice the WHO guideline of 2ug/L. Samples taken four days later showed negligible concentrations and none after treatment.” (10).

The following statement was published in the Victorian Water Quality Monitoring Network Annual Report 1993; p111 "The 1990 review of the Victorian Water Quality Monitoring Network (Rural Water Corporation 1991) proposed additional and seperate monitoring for rivers and streams, lakes, reservoirs and wetlands, as well as an increase in the type and number of parameters to get utilised ... There are a number of recommendations from the 1990 Review that are still to be implemented in the VWQMN. Listed below are the remaining Review recommendations as well as three recently proposed future directions for the VWQMN, implentation of which depends on whether resources are available... Organochlorine compounds are widely used in pesticides, herbicides & algacides. These substances are potentially toxic to non-target species, not readily broken down in the environment, bioaccumulate and tend to accumulate in sediments. Monitoring of compounds such as Aldrin, Dieldrin, DDE, DDD, Heptachlor, Heptachlor epoxide, Hexachlorobenzene, Lindane, Methoxychlor and Endosulphan provide base information and indicate potential sources of environmental and health problems". (13)

The only pesticide monitoring published by the VWQMN is a small note in Table 6 entitled 'Parametres monitored as part of the Murray Darling Basin Committee Physico-Chem Baseline Monitoring Programme. Additional Parametres Monitored Herbicides/Pesticides. Denotes monthly monitoring in the Murray River at Morgan (SA) only'. (16) This is also backed up by Table 1: Summary of Network Water Quality Sampling in Victoria (18) which shows that out of the following programs; VWQMN, EPA, MDBC, Melbourne Water, Salinity Program and Biological, only the MDBC is listed as monitoring for herbicides/pesticides. And this was based on information collated in Morgan South Australia!

In 1994, the SWL (a business unit of the Rural Water Corporation) and the Melbourne Water Laboratories (a business unit of Melbourne Water Corporation) were merged to form a private company trading under the name of water Ecoscience.After 1996 Water Ecoscience became responsible for data collected by the Victorian Water Quality Monitoring Network. Again pesticides were not included in the monitoring.

"Following the 1996 Review, a discussion paper was produced (Testing the Waters. The 1996 Review of Victorian Water Quality Monitoring. Technical Discussion Paper" (14). Written in the Review; "The State and Commonwealth governments are mainly responsible for statewide water quality monitoring. Statewide requirements are currently funded by two Government agencies - Department of Natural Resources and Environment and the Environment Protection Authority. In addition to this, Melbourne Water and Rural Water Authorities are responsible for the management of public and private diversions...Overall responsibility for water quality influences is assigned through legislation and policies such as State Environment Protection Policies (SEPP's) administered by the EPA and NRE ... Monitoring was reviewed in 1991, with the current program based on that review, although the recommendations have only been partially implemented, mainly due to funding constraints...Recommendations of the previous review have not yet been implemented ... Monitoring of hydrocarbons and biocides in sediments and metals in water and sediments". The final copy of the 1996 Review (dated September 1997) appears to avoid any discussion about pesticide monitoring. (15)

During the early to mid 1990's the Department of Agriculture also started looking more closely at the impacts of pesticides on waterways (7). The Mitchell River was the main focus area, where traces of atrazine, endosulphan and chlorpyrifos were detected in 1993. Testing expanding into the next year into 5 regions of Mornington Peninsula and Gippsland, including possibly the water supply for Thorpdale. No detections were found at Thorpdale but traces of pesticides (Dieldrin and DDT) were found in very close proximity to the main offtake on the Mitchell River, upstream of the intensive horticultural practices associated near Lindenow. Other pesticides detected in a variety of locations included Atrazine, Metribuzin, Linuron, Diuron, Simazine, Endosulphan, Dieldrin, DDT and Methamidophos. (8)

In the mid 1990's researchers were finding pesticide pollution in groundwater, particularly in northern Victoria near Horticultural areas. (21). Research found "low level contaminations by organochlorinated pesticides (total benzene, hexachloride, heptachlor & its epoxide, total chlordane, total endosulphan, dicloran, endrin, dieldrin, lindane, DDT, DDD, DDE & dicofol), organophosphorous pesticides (chlorpyrifos, fenitrothion, dichlorvos, parathion, ethion, diazinon, mevinphos, tetrachlor, fenvinphos and fenchlorvos), s-triazines (atrazine, simazine, hexazinone and prometryne) and amitrole. Groundwater contamination was identified to be at higher levels in the horticultural areas of Ardmona. Surface water reported only minor contamination" (21)

Melbourne Water did produce a UWRAA report in 1996 looking at a range of contaminants found in sediment in the Yarra Catchment. The report mainly looked at substances such as PAH's (Polycyclic Aromatic Hydrocarbons), however some pesticides were also included. Tests for BHC, Lindane, Heptachlor, Aldrin, Chlorpyrifos, Chlordane, Endosulphan, DDT, Dieldrin, Methoxychlor were carried out. Positive results for some of the pesticides were found mainly well downstream of Melbourne's water supply, however Dichloran, BHC, Lindane, Heptachlor and Heptachlor Epoxide were found in sediments quite a distance upstream from the Sugarloaf Reservoir offtake. Sediment levels for Heptachlor and Heptachlor Epoxide were very high at a sampling location downstream from Reefton, yet it appears that these levels have not been recorded by Melbourne Water testing at Sugarloaf Reservoir.(22)

Melbourne Water also initiated Streamwatch in the mid 1990's to better research toxicants in the Yarra River. However pesticide testing was generally unlikely to be included in this program. "Baseline data plays an important role in assessing the performance of these initiatives and such data sets are being developed for Melbourne by the Melbourne Water Corporation (eg Lewin 1997, Melbourne Water Corporation 1997). The data collected for this study forms part of the Melbourne Water's ongoing stream monitoring program, "Streamwatch" which is an extensive program including monitoring of water quality, biological health, toxicants and litter. Aside from the Streamwatch program, no extensive studies of stream toxicants have previously been undertaken in Melbourne. However, ther have been a number of site specific studies (eg Bagg et al., 1981, Pouliot 1993, Reed 1992) and an earlier study, on heavy metals only, conducted by the Victorian Environment Protection Agency". (33)

This LWRRDC Report (33) looked at sediments at 44 locations across the Port Phillip Bay and Western Port Bay catchments. Five of these sites were located above the offtake to Sugarloaf Reservoir, however individual results tabled in the report were not given in site specific detail, meaning that it is impossible to work out where the positive samples were taken and in what quantities, many of which were located in heavily urbanised areas well downstream of domestic water supply offtakes.. Pesticides found in sediments in the LWRRDC report included; HCB, Dicloran, Total BHC, Lindane, Heptachlor, Aldrin, Chlorpyrifos, Total Chlordane, Heptachlor Epoxide, Total Endosulphan, op-DDE, pp-DDE, op-DDT, pp-DDT, Dieldrin, Endrin, op-DDD, pp-DDD, Methoxychlor. Mean readings included; Dicofol 0.12mg/kg, op-DDT, pp-DDT 0.11mg/kg, Total Endosulfan 0.045mg/kg, Endrin 0.035mg/kg, Diedrin 0.028mg/kg, Methoxychlor 0.025mg/kg, Total Chlordane 0.020mg/kg, Heptachlor Epoxide 0.020mg/kg, Total BHC 0.014mg/kg, Heptachlor 0.013mg/kg, Chlorpyrifos 0.012mg/kg, Dicloran 0.010mg/kg, op-DDE, pp-DDE 0.010mg/kg, HCB 0.007mg/kg, Lindane 0.005mg/kg, Aldrin 0.005mg/kg. Total OC Pesticides 0.24mg/kg. (33)

On a national level interest was also increasing about the issue of monitoring pesticides in water. "Recently the first reports of monitoring pesticides in waterways in this country have been published and the results are of concern". "... It is generally believed to be the case that surface water management is the principle mechanism for river contamination by pesticides" (34)

By the late nineties the Government was also acknowedging that "low level" pollution of groundwater had occurred in Victoria, possibly in domestic supplies(p19); “The herbicide Atrazine has emerged as a significant contaminant of groundwaters in Europe and North America. Despite its limited usage in Victoria some has been found at concentrations less the guideline values, in drainage waters from irrigation areas and also in vulnerable aquifers used for drinking water supply. (9) (p20) Apparently the Government was also stepping up its monitoring of pesticides; "Additional monitoring for other organics is currently being undertaken for the MoU between water authorities and the Minister. These organics include industrial and other contaminants, organochlorine pesticides and 2,4-D..."Since 1997 Water Authorities have been signing memoranda of understanding (MoUs) with the former Minister of Agriculture and Resesources. These include amongst other things, the requirement for non-exempt supplies to meet WHO, 1984 Guidelines by the year 2000". (9)

Furthermore Water Ecoscience, who were contracted by the State Government to test waters for pesticides claimed in 2001: "Most pesticide concentrations were below the detection limit. No incidents in which concentrations exceeded WHO Guidelines occurred during the period July 1999-June 2001.(19)" This statement therefore claims that positive samples had been detected but no elaboration was made in the report about locations of the sources. The levels of detection used by the State Government were also quite high as is explained in the table below;

A massive leeway appears granted for 2,4-D. Of all the pesticides tested for with the baseline data, only 2,4-D limits were set well above the levels set for future health limits. This means that large amounts of 2,4-D may well have been entering waterways but monitoring levels were set too high to be detected. This is important as a large proportion of many domestic water supplies in Victoria are dominated by cropping and grazing where 2,4-D use is commonplace.

In terms of water authority testing, results from this report indicate that only South Gippsland Water provided access to tests going as far back as 1991. Testing regimes instigated by water authorities largely before 1995 are unknown. The Melbourne Metropolitan Board of Works (MMBW) may have been testing for pesticides, however records accessed via FoI only go back as far as February 1997.

Other water supply authorities were also sampling but these samples were often limited and haphazard. Such sampling certainly did not test for all pesticides used within domestic water supplies and water authorities were under no obligation to inform other State Government Department's if positive samples were detected.

A Freedom of Information request from Department of Human Services (State Government Victoria) (Incorporating; Health, Community Services, Mental Health, Senior Victorians and Housing)

It said;"The Department's Environmental Health Unit has advised that since 1 July 2004, the quality of drinking water in Victoria has been regulated under the Safe Drinking Water Act 2003. The state's water businesses are required under this act to notify the department of any incident where the drinking water they supply to the public presents a risk to public health. There are no recorded notifications of instances of pesticide pollution in drinking water supplies for the period 1 July 2004 to 3 January 2008.

For the period 1 January 1998 to 30 June 2004, there were no formal regulatory arrangements in place regarding reporting of incidents in drinking water supplies."

Please note that Friends of the Earth in this study compiled a list of 140 incidents of pesticides being detected in water supplies in Victoria between 1996-2007. It appears that if pesticides are detected under the Australian Drinking Water Guidelines limits for particular pesticides, the incident doesn't have to be reported to DHS. Prior to 30 June 2004 it appears that DHS didn't have to be consulted at all by water authorities if a pollution incident occurred. It also appears that with the instigation of the Safe Drinking Water Act in 1994, some water authorities deemed that their catchments were of a low risk and stopped testing for pesticides at this time (re: North East Water, East Gippsland Water, Westernport Water). According to East Gippsland Water; The Australian Drinking Water Guidelines (2004) state that “Routine monitoring for pesticides is not required unless potential exists for contamination of water supplies”.

Although pressure from Friends of the Earth has seen North East Water start testing gain in late 2007 and Westernport Water have been reported as recommencing their pesticide testing in May/June 2008.

It should also be pointed out that the European Union has a policy that pesticides should not be detected in drinking water (Drinking Water Directive 98/83/EC). The EU's position is that "The value of 0.1 µg/l is a substitute for zero, not present in water or below the detection limit". Given that position any positive reading would be regarded as a breach to the EU. Given this fact, most of the Health Values for pesticides in Australia are well over the EU limit.

The European Union (EU) has issued the drinking water directive of 1998 that sets a maximum concentration of 0.0001mg/L for individual pesticides or degradation products and 0.0005mg/L for total pesticide residues in drinking water after treatment (Acero et al, 2000, http://europa.eu.int/water/water-drink/98_83en.pdf)*.

5. Results of Survey

In 2007 the Department of Primary Industries published the "Review of agrochemical contamination of waterways within agricultural areas of Victoria”. In regards to surface water the review said p7; “There has been very little monitoring of agrochemicals in surface waters in Victoria. Organochlorines found in a number of areas, particularly in the Ovens catchment. Atrazine, metribuzin, endosulfan, and chlorpyrifos detected in Gippsland surface waters (concentrations low and below guideline values). Monitoring in the Melbourne metropolitan area has indicated agrochemical contamination from urban sources.” (23)

What can be added to this statement is; Water authorities in Victoria have in recent years detected the following pesticides in surface water in domestic water supplies; 2,4-D, Hexachlorobenzene, Pentachlorophenol, Dieldrin, Glyphosate, Aldrin, Heptachlor, Hexazinone, Methoxychlor, Simazine, Lindane, Chlorpyrifos, Endosulphan and Atrazine. Acrolein has also been detected when used and Bifenthrin, Esfenvalerate & Taufluvalinate have been detected in relatively high levels upstream of a town water supply. (Barwon Water also detected Temephos, MCPA, 245TCP and 4, chlorophenoxyacetic acid between July 2007-July 2008).

The most serious concern appears to be the open aquaduct supply system to both Wurdee Boluc Reservoir and Stony Creek Reservoir managed by Barwon Water (Geelong and district drinking water). Three instances of pesticides (2,4-D & Glyphosate) entering the Wurdee Boluc system have been detected in the past 4 years (An additional 15 instances were detected in the Wurdee Boluc System between July 2007-July 2008). One incident possibly lasting for some time (3 months), with 2,4-D readings in May 2003 breaching the ADWG health value, however this was not widely known because it occurred before July 1 2004, when such an incident would have to have been reported under the Safe Drinking Water Act. See here for more information about Geelong's water supplies.

Wurdee Boluc Aquaduct can be impacted by farm run-off at several location where the water level is below the upslope.

High readings of 2,4-D were also recorded by Barwon Water in August 2003 at Wurdee Boluc and Stony Creek Reservoir #3. The May Wurdee Boluc 2,4-D Incident, remains the only example of pesticide levels breaching the ADWG health value anywhere in the state over the 1998-2007 period. The Stony Creek Reservoir incident also recorded relatively high levels of 2,4-D in August 2003, 66% of ADWG health value and 200 times higher than the ADWG guideline value.(2,4-D was also detected in the Moorabool system June 2008). It is clear that agricultural practices, cropping, in close proximity to the aquaducts are the culprits for this pollution. Was an audit of cropping located nearby the aquaducts conducted by Barwon Water and why did three seperate incidents occur within a 3 month time frame with the same pesticide?

Bolwarrah Aquaduct, part of Geelong and district water supply.

2,4-D runoff and use in the Broken Creek catchment in the north of the state is also of concern, with a reading 170 times higher than the guideline value occurring in June 2005 at Numurkah.

The longest recorded residues of pesticides have been recorded again by Barwon Water with hexazinone leaching into Geelong’s water supply (at low levels) for almost 3 years (4 years after getting access to Barwon Water data in September 2008). The hexazinone was found to be leaching from a plantations managed by Hancock Victorian Plantations, with some hexazinone residues detected 50km offsite. Only one water authority, Barwon Water, tests for hexazinone (North East Water began testing again in 2008). If this incident were to happen (or has happened) elsewhere in Victoria noone would be the wiser, which is quite surprising considering the high leaching and long residual effect of hexazinone.

1400 ha of pine plantations surround Korweinguboora Reservoir in Geelong's water supply. Hexazinone leached from this site between December 2004 - October 2007.

Also of concern is the detection of Atrazine, Glyphosate and Endosulfan in channels managed by Goulburn Murray Water. Low levels of Atrazine and Endosulphan were detected each year over a 3 year period in a project under the control of Goulburn Murray Water.(20) What was alarming was that although these detections were considered to be low, none were detected by Goulburn Valley Water, Coliban Water or Lower Murray Water, the authorities responsible for providing drinking water. High levels of Glyphosate were also found to be found in Broken Creek and Lake Nagambie after weed control activities carried out by Goulburn Murray Water (24). Once again though, the events were not picked up by Goulburn Valley Water monitoring indicating that pesticide 'spikes' can get through the monitoring system undetected. (It should also be noted that Goulburn Murray Water recorded 16 positive readings for Endosulfan (4) and Atrazine (12) at the Lake Nagambie/Kirwans Bridge sample point during the same study. The township of Nagambie draws water from the Nagambie Lakes. If these pesticides were detected at Kirwans Bridge there is also a possibility that they may also have been present in the Nagambie supply. Total concentrated endosulfan between October to December 2005 was the highest anywhere in Goulburn Murray Water's 6 irrigation areas. Interestingly this same water body is now the water supply for the cities of Bendigo and Ballarat since the opening of the Goldfields Pipeline in 2008. Water for Ballarat and Bendigo is extracted from the Waranga Western Channel at Colbinabbin. This water in turn is sourced from the Warange Basin after being diverted by the Stuart Murray and Cattanach Canals at Goulburn Weir).

Broken Creek about 6km upstream from Nathalia. Glyphosate is used to kill aquatic weeds in this water supply and was recorded at high levels in 2005 above Nathalia. 2,4-D, well above guideline limits for drinking water was detected in Broken Creek at Numurkah in June 2005. Pentachlorphenol detected at Numurkah also in 2005. Numerous detections for Atrazine, Simazine and 2,4-D were detected at Numurkah, Wunghnu and Nathalia over 2010-2012

The much publicised triazines Simazine and Atrazine were recorded in 4 instances by water authorities and 33 times in water supplies by a study by Goulburn Murray Water. Simazine was recorded at Rocky River (Orbost water supply) leaching from a bluegum plantation in August 2002 and atrazine was found in May 2006 at three locations on the Murray River by Lower Murray Water. The Atrazine readings at three locations in the Murray River (0.03µg/L), with lower levels detected by GMW in channels supplying towns Katatamatite, Kerang, Tatura, Rochester/Corop, West Boort?. The Simazine levels (0.2µg/L) in Rocky River catchment are also of concern and were detected by the company Harris Daishowa. These levels were a long way under the ADWG levels for Atrazine (40µg/L) & Simazine (20µg/L), however it would be erroneous to assume that because low levels of pesticides are detected that they are not having an impact. Levels of atrazine and simazine as low as 0.1 µg/L have been found to chemically castrate amphibians. See this website for further details.

"A number of organochlorine chemicals called persistent organic pollutants (POPs) were detected in Victoria’s water supplies. Although no longer used in Australia, most were applied extensively in agriculture from the 1950s to the 1990s when they were deregistered. These include the grain fungicide, hexachlorobenzene as well as insecticides like heptachlor, dieldrin and aldrin. Pentachlorophenol, a disinfectant, also used to treat wood was also detected. These POPs are very persistent in the environment partitioning to soil and sediment, as well as traveling vast distances via air and water currents. POPs are toxic and can cause cancer and other adverse health effects. They bioaccumulate in living things and are found in the blood and breastmilk of humans and wildlife. " Mariann Lloyd-Smith (National Toxics Network)

Again Barwon Water recorded a reading 3 times over the guideline limit for Dieldrin in October 1999. Melbourne Water’s Kallista supply also suffered from organochlorine problems in 2000, when traces of aldrin, heptachlor and lindane were found at St John Hill Reservoir Kallista. This reservoir sources its water from Silvan Dam, and little light has been shed on how these pesticides ended up being recorded at St John Hill. Heptachlor was also found at Katamatite by Goulburn Valley Water and high livels of Hepatchlor were detected in Yarra River sediments in the mid 1990's.

St John Hill Reservoir Kallista

Far from providing a detailed analysis of pollution of domestic water supplies, the information does allow analysis of risk areas. Because standardised pesticide monitoring is not required throughout Victoria, these results only give a broad picture of the situation. It is likely that other pesticides would be detected if testing was standardised. For instance Gippsland Water does no testing, yet some communities in the region lie downstream of irrigated farming and forestry land use.

The analysis also only touches on treatment techniques used to 'filter out' pesticides. It is Friends of the Earth’s assumption that these pesticides should not be leaching into waterways at all. To rely on the use of ‘filters’ is a high risk strategy particularly in small communities where sophisticated forms of treatment may not exist. For the sake of brevity, the discussion of filter/treatments only looks at communities which have been subject to pesticide pollution.

* means no testing *means dates included under FoI

Results from FOI's show a 37% return based on pesticide monitoring by all authorities since 1991. This means 63% of information pertaining to pesticides in drinking water since that time could not be determined in this project. This figure does not include the range of pestides not tested for by authorities, indicating that existing testing may well be 'stabbing in the dark' in regards to the true extent of pesticide contamination of drinking water in Victoria..

8. The Red List

The following list gives details about which communities are at the most risk in terms of pesticides and drinking water in Victoria. The list is not exhaustive and only provides locations that are supplied water by water authorities. Localities not supplied with water from water authorities have not been added to this list.
(Not including specific details from Grampians Wimmera Mallee Water as open channels are being replaced by the Wimmera Mallee Pipeline Project. Polluted runoff and poor quality water in these channel systems will hopefully become a thing of the past, although according to this article maybe not)

9. Discussion

9.1 Barwon Water

Dec 07: Plantations and native forest (green) in the Moorabool She Oaks and Stony Creek Proclaimed Water Supply Catchments. Brown = pine, yellow = hardwood.

Dec 07: All land use within Moorabool (Sheoaks) and Stony Creek Proclaimed Water Supply Catchments. Light Tan=cropping areas, Dark tan=grazing areas. Orange=canola planted in 07.

October 2008: Canola now being grown adjacent to Wurdee Boluc Inlet Channel (5km west of Deans Marsh) possibly meaning higher potential for pollution from agrochemicals into Geelong drinking water. This is the first instance recorded of canola being grown in such close proximity to the channel and could represent a new hazard to water quality if grown in large enough areas, particularly areas upslope of the supply channel. The channel can be seen running through the yellow canalo field.

Cropping 1km upstream of Bostok Reservoir- Geelong Water supply.

Potato growing inside Ballarat's water supply

Map with Ballarat's water supply highlighted. Light green=native forest, dark brown=radiata pine plantations managed by Central Highlands Water, dark blue=reservoirs, orange=cropping, dark orange=potatoes 06/07, Tan=grazing. The cropping, grazing and potatoe boundaries outlines change from year to year and as such are only approximate. The catchment is dominated by cropping, yet Central Highlands Water only test for two currently used pesticides.

Same colour coding for Lal Lal catchment which also supplies drinking water to Ballarat. Lal Lal is dominated by pasture, with cropping mainly in the northern half.

Committee of Enquiry Into Effects of Pesticides 4th Meeting: "4(e) Learmonth Waterworks Trust - responsible pollution of town water supply..."

Agricultural Chemicals Committee (15th meeting 1980?): The Soil Conservation Authority submitted 11 sediment samples from Lal Lal Reservoir which supplies water to the City of Ballarat... Reservoir residues ranged from 0.003 to 0.015mg/kg total DDT and input streams from 0.003 to 0.022mg/kg total DDT..."

 

Time covered in FoI request: 3/10/06 - 7/12/07

Pesticides tested once a year (November) for; DDT, Aldrin and Dieldrin, Chlordane, Hexachlorobenzene, Heptachlor, Heptachlor Epoxide, Lindane, Methoxychlor, 2,4-D, Atrazine.

No positive pesticide results.

Location of test sites: Amphitheatre, Avoca Clear Water Storage “CWS”, Beaufort CWS, Blackwood CWS, Clunes CWS, Daylesford Low Level Basin, Dean CWS, Forest Hill CWS, Glut-Raglan Pipeline (Raglan), Lal Lal CWS, Landsborough Reservoir, Learmonth CWS, Maryborough CWS, Waubra CWS, White Swan CWS.

April 29 2009: Melbourne seeks water from NSW (by Peter Hunt Weekly Times)

Melbourne Water has investigated buying water out of NSW this season, according to a senoir government source. The city water corporation "sounded out" some water brokers to determine what options they had, despite the Victorian Government repeatedly declaring it would not buy water to supplement Melbourne's needs. A spokesman for Melbourne Water denied the corporation had ever examined the option. However other water corporations, such as Coliban Water have already purchased seasonal allocation water from NSW Murrumbidgee irrigators to supplement Bendigo's supplies. Coliban Water is able to buy Murrumbidgee allocations to replace water supplied by Lake Eildon to Robinvale and Sunraysia irrigators. The water is then freed up in Lake Eildon to supply Bendigo, via the Western Waranga channel. Melbourne Water has investigated using exactly the same process to supply water via the north-south pipeline. Until the end of March, NSW State Water processed a record net transfer of 385,580 megalitres from NSW to South Australia and Victorian irrigators and government agencies.

2 May 1969 Letter to Bairnsdale Waterworks Trust from Agricultural Department: "... regarding aerial spraying on river flats adjacent to the Mitchell River and possible danger of pesticides contaminating the Bairnsdale water supply. As area of vegetables at Lindenow was sprayed last summer from the air at a point approximately 15 miles upstream from the Bairnsdale pumping station... These crops were sprayed four times from December to February with DDT at the rate of 1 pound of active ingredient per acre, one of the DDT sprays did include Maneb at the rate of 2 pounds per acre ... Ground crops were also sprayed by ground machines including - Insecticides: Disulfoton, Demeton-s-Methyl, DDT and Trichlorphon - Fungicides: Copper Oxychloride, Quintozene and Dichloran - Weedicides: Linuron, Prometryne, Chlorthal and Trifluralin... Many of the crops sprayed by ground machine run right through to the riverbank, but it is unlikely that the spraying operations, whether from the ground or air could be responsible for any contamination. However pesticides could be introduced into the stream by operators washing spraying equipment in the river, allowing washings to be returned to the river or by disposing of empty containers in the river..."

Current Testing Regime for Pesticides

None since 2003. "EGW is still considering the worth of ongoing monitoring for pesticides..." Established a process with Parks Victoria to ensure that (they) are informed of any chemical usage in catchments about offtakes (eg ragwort, blackberry spraying).

Monitoring for pesticides has been undertaken by EGW. Electronic data goes back to 2000. Hardcopy lab reports go back to 1995, with samples taken on a quarterly basis, from 1995 to 2001. Since that time samples have been taken in July and August 2002, February, March and July 2003. "The pesticides analysed for were consistent with World Health Organisation Guidelines for Water 1996 and the previous MoU with predecessors of DSE. These were; 2,4-D, 4-4-DDT, Aldrin, trans & cis chlordane, dieldrin, heptachlor epoxide, lindane and methoxychlor, as well as a general pesticide scan. If the pesticide scan identified the presence of a substance it was pursued further for identification, however no traces of concern were found". "Following the development of the Safe Drinking Water Act and the Risk Assessment process that EGW completed for its water supply catchments in 2003/4, it was determined that, as evidenced by the absence in historic data, the risk of pesticide presence in the water supplies was very low."

In the study, “Horticultural Pesticides in residues in water. Research report No.146 Department Agriculture November 1993”, which focused on horticultural activities in the Mitchell River, one site was located upstream of the extensive cropping area of the Mitchell River floodplain near Lindenow. One would have thought that pesticide residues would have been detected downstream of the crops, however Site 1, was located in very close proximity to the Mitchell River pumping station. In 1992 Atrazine was detected at this location at 0.02µg/L. In 1993 Endosulfan was detected at this location at 0.01µg/L and 0.014µg/L. One can assume that the pesticides were washed upstream with the potential of being taken up via offtake.

In the follow up study, “Horticultural pesticide residues in water. A survey of pesticide residues conducted in Gippsland Victoria, 1994 Agriculture Victoria, Research Report Series No. 146 Feb 1995” Dieldrin was detected at the upstream site at 0.02µg/L, DDT at 0.017µg/L.

September 15 2006: Seaspray Water Untested

NO regular testing for herbicides, pesticides and other chemicals used in plantation timber and farming are carried out on Seaspray's water supply. Gippsland Water has confirmed while it tests for herbicides and pesticides quarterly in Moondarra, which provides drinking water for Morwell and Traralgon, no such testing is currently carried out on Seaspray's supply unless the organisation is aware of a "specific event". Seaspray draws its water from Merriman's Creek, which is surrounded by plantation pine and farmland for much of its length. Steep hillsides planted in pine run along the upper reaches of the creek and its tributaries. Hexazinone, a pesticide used on plantation pine, was detected in the Korweinguboora Storage, which is part of Geelong's water supply, in 2005. The area is surrounded by pine plantation owned by Hancocks. A reading of 9.4 parts per billion was detected - more than four times the Australian Drinking Water Guideline for hexazinone of two parts per billion. Barwon Water confirmed it had taken "strong action against a forestry operator in April 2005, following low-level detection of hexazinone in raw water samples from the Korweinguboora Reservoir catchment". "The effect of Barwon Water's responsible action was to prevent the forestry operator from using any pesticide or herbicide in any Barwon Water catchment while the notice was in force," Barwon Water's media release said. "Barwon Water has since developed a protocol with the forestry operator whereby no control chemical, such as hexazinone, can be used in Barwon Water catchments without prior agreement from Barwon Water." A statement from Gippsland Water said local companies had "so far been excellent" in providing details of chemicals they were using. "In the instance of a specific event occurring around a catchment, Gippsland Water will assess on a case-by-case basis and initiate water quality testing and monitoring for specific chemicals if required," a statement from Gippsland Water said. "Gippsland Water conducts regular water quality tests and monitoring on its source and raw water supplies (including some rivers), and from the `off-take' section of a water source before it enters a water treatment plant. "Regular tests assess turbidity (a rapid measure of suspended solids), pH levels, ammonia, iron, manganese, alkalinity and E. coli bacteria. "This ensures Gippsland Water's drinking water quality is meeting industry standards," the statement said.

September 15 2006: No Chemical Testing

NO testing is done for herbicides, pesticides or veterinary chemicals on rivers entering the Gippsland Lakes. EPA Victoria, the West Gippsland Catchment Management Authority and Gippsland Water have all confirmed they carry out no such testing. The Gippsland Coastal Board has confirmed the same. Former Wellington Rivers Authority general manager Ross Scott has been critical of a lack of testing for chemicals used in plantation timber and on farms. Current testing is geared towards nutrients and much of the testing which is carried out is "schoolboy stuff", according to Mr Scott. WGCMA chief executive Geoff Hocking said very little monitoring for chemicals was done. "Hopefully as part of the (Draft Sustainable Water Strategy) ... we can test for pesticides and herbicides and those sorts of things," he said. "There's very little monitoring of it. A fair bit is used (in the catchment) ... some of that will be getting into rivers and streams." However WGCMA will do a pesticide study on the Traralgon and Narracan creeks. Gippsland Coastal Board Gippsland Lakes planning officer Chris Barry said there was "no monitoring for these matters". "We have to look at where the greatest risks are," he said. Gippsland Water does quarterly tests for chemicals at Moondarra Reservoir, from which Traralgon and Morwell draw drinking water. A 1996 submission by Gippsland Water regarding the Review of Agriculture and Veterinary Chemicals highlighted its concerns regarding access to listings of agriculture chemicals in use, methods of chemical application and potential for environmental contamination, and that investigation into misuse or overspray of chemicals around waterways was also an issue. In a statement to the Gippsland Times, Gippsland Water said it had lodged a formal submission during the 2006 review of the Agricultural and Veterinary Chemical (control of use) Regulation 1996. "The revised regulation is yet to be released," the statement said. Meanwhile the EPA confirmed it does not carry out tests in local rivers for chemicals used on plantation timber or in farming. "EPA Victoria undertakes regular biological monitoring at more than 1000 sites in Victoria," it said via a written statement. "Biological monitoring provides an indicator of overall river health."

May 29 2007: Chemical Cocktail

"WATER from the Latrobe River has registered what is believed to be one of the highest levels of antibiotics and anti-inflammatories detected in any river system in the world. Private testing conducted at 15 sites in rivers and drains around the Macalister Irrigation District has discovered a cocktail of antibiotics and anti-inflammatories used in dairyfarming. The tests found large amounts of oxytetracycline, a propellant used in the application of anti-inflammatories. The anti-parasitic agent DEET, which is also used to wash down dairy sheds, was found at all 15 sites tested. No testing was conducted in the Macalister River, which is also part of the MID and from which Maffra draws its urban water supply. Gippsland Water has confirmed previously it does not test Maffra's water for chemicals or pharmaceuticals....Maffra's water supply, on the other side of the MID, remains untested for chemicals, antibiotics and anti-inflammatories..."

June 1 2007: Testing Regime Disgrace

A VICTORIAN Agricultural Chemicals Advisory Committee representative has slammed Gippsland Water for its lack of testing for chemicals and pharmaceuticals in the Maffra Weir. But the representative says the water authority should not shoulder all the blame. The comments follow test results which found the nearby Latrobe River had some of the highest levels of antibiotics and anti-inflammatories found in any river system on the planet. VACAC representative Anthony Amis said the lack of testing of Maffra's water was a "disgrace". "A big concern would be the impact of agricultural chemicals which might be washing off (into the Macalister upstream of Maffra's drinking water offtake)," Mr Amis said. "Although you can't blame Gippsland Water wholly because the use of agricultural chemicals is highly problematic - Gippsland Water don't know what chemicals are being used as the people using them are under no obligation to tell the water authorities." Gippsland Water made a submission last year to a review of the Agricultural and Veterinary Chemical (control of use) regulation 1996. The water authority highlighted its concerns regarding access to listings of agricultural chemicals in use, methods of chemical application and potential environmental contamination. It also said investigation into misuse or overspray of chemicals was an issue....Mr Amis also sought assurances chemical treatments used to kill water weeds by Southern Rural Water in major channels in the Macalister Irrigation District were not resulting in chemicals such as acrolein and glyphosphate entering the Macalister River upstream of Maffra's drinking water offtake.

June 1 2007: SRW Tests Show Chemicals

TESTS have confirmed the chemical acrolein has been detected in the Thomson River after being used as a weed killer by Southern Rural Water. The chemical is used to kill submerged weeds in SRW's main southern and main northern channels. Freedom of Information documents obtained by the Gippsland Times show levels of almost three parts per million were recorded at a site referred to by the test papers as "Heyfield Intermittent Town Supply". A reading of more than four parts per million was detected at the point referred to as "Swimming Pool Check". Both sites were tested as part of the main southern channel. In the main northern channel, readings of five parts per million were recorded at sites referred to as "Football Lane" and "Coloe's Road". The testing was carried out by SRW following use of the chemical. The SRW response to the FOI request also states SRW "does not routinely monitor chemicals within its water supply networks" as it is not required to by law. Victorian Agricultural Chemicals Advisory Committee representative Anthony Amis questioned what arrangement SRW had with regard to alerting water authorities of the chemical treatments and sought assurances the chemicals could not enter the water supply for Maffra via the Macalister River. While he admitted acrolein had a relatively short half life of around two days, he said the chemical had been the subject of a fish kill investigation in the Goulburn River - an irrigation district. "Fingers were pointed at use of acrolein which is highly toxic to fish," he said. "There was a report done by the EPA." SRW also uses roundup as a form of weed control. Tests for glyphosphate came in below the detection limit, according to the FOI document. An SRW spokesperson had not responded to request for an interview at the time of going to print.

March 10 2010: Growing Pains (E. nitens plantations potentially toxic)

Susie points to a broad bank of plantation nitens: ''They're in my catchment,'' she says. The trees grow next to a creek, which funnels into Middle Creek - the brook that runs past Susie's house. ''The issue is very dear to my heart because I suffer from multiple chemical sensitivities, which is why I live where I live, away from most people and most pollutants, so it's something of great interest to myself and any other person who uses the water,'' she says. Susie pumps water out of the river for domestic uses such as bathing. She's capturing rainwater for her drinking supplies, but there's plenty of others around Gippsland who are drinking from rivers that also sustain nitens plantations. On the south side of the Strzeleckis, Margaret and David Pellew hire out a small number of forest cabins on the banks of the Tarra River. The Tarra supplies drinking water to the Pellews and nearby towns such as Devon and Yarram, as well as sustaining nitens plantations. The Pellews were already aware of the Tasmanian controversy when The Age visited this week. ''We're concerned and we would certainly like to know more about it. We'd like to know scientifically how it affects the water,'' says Margaret. Plantation company Hancock says its nitens crop covers about 5600 hectares of Gippsland. Most of those nitens are grown in pockets across the Strzeleckis, but there are also some planted in the Great Dividing Range north of Noojee. The company withdrew its original offer to allow The Age access to its plantations, but in an email Hancock spokesman Steve Wentworth said the company was aware of the Tasmanian controversy.

As people such as the Pellews start to ask questions, local water authorities, at the instruction of Victoria's Health Department, do not seem interested in chasing answers. South Gippsland Water, the authority which harvests the Tarra River for Yarram's supply, says it will not be initiating any investigations. ''We are in contact with [the Health Department] regarding this issue and as yet have received no advice to carry out further water testing,'' spokeswoman Ros Griggs says. ''South Gippsland Water will be waiting for advice from our health regulator regarding any additional requirements.'' Neighbouring authority Gippsland Water confirms that the town of Seaspray is drinking from a river catchment that sustains nitens, but spokeswoman Leah Mether says there will be no change to testing regimes in the short term. ''Gippsland Water treats all its water supplies to ensure compliance with the Safe Drinking Water Act, and has not received any advice from the Victorian Department of Health to alter these existing treatment methods,'' she says. The Victorian Health Department regulates drinking-water safety in this state, and spokesman Bram Alexander says there does not appear to be any danger to Victorian water supplies. ''We are looking at this issue closely. Based on available evidence, it is too early to draw any conclusions. However, from our regular monitoring of water quality in those two water authorities, there is nothing to suggest drinking water supplies are unsafe,'' he says. Alexander declined to clarify whether ''looking at the issue closely'' meant the department was running its own tests on Victorian water, or merely reading the Tasmanian newspapers.

9.6 Goulburn Murray Water

Waranga Western Channel

Time covered in FoI request: 1996 - 3/1/08

Goulburn Murray Water does not supply drinking water, it supplies untreated raw water to its water suppliers, Goulburn Valley Water, North East Water, Coliban Water and Lower Murray Water. The water authorities then sell water to domestic users as well as supply and treat the water.

Lake Nagambie, Murray River, Broken Creek all sprayed with Glyphosate to control aquatic weeds. Spraying also occurs in irrigation channels, drains etc. These channels may also be used for drinking water.

Goulburn Murray Water has carried out investigations into the use of pesticides in some of their region. Some of the results of these reports were used in determining potential pollution of drinking water sources. Most notably;

CSIRO/Goulburn Murray Water "First-Tier Assessment of the Risks Associated with Pesticides used in the Goulburn Murray Irrigation Areas" September 2003. Report looks at the risks associated with pesticide use in the GMW Irrigation Areas to water quality and through water quality changes to humans, stock, aquaculture, food industries, pastures, and aquatic flora and fauna and aquatic ecosystems". Determined top ten pesticides posing highest overall risk; azinphos-methyl, copper hydroxide, parathion methyl, chlorpyrifos, omethoate, esfenvalerarate, methomyl, thiram, bifenthrin, mancozeb. In terms of drinking water;

p2 "The relative risk of off-site migration of pesticides via run-off from irrigated area was also assessed. Please note that it was not included in the combined risk, as the run-off does not normally reach the irrigation channels, especially because the irrigation channels are almost universally at a higher elevation than surrounding land. However, at certain locations, not provided with a G-MW drainage service, irrigation customers are sometimes permitted to pump flood waters that accumulate following heavy rain into adjacent irrigation channels."

"Pesticide Monitoring in Goulburn-Murray Waters Irrigation Supply Channels Covering the Six Irrigation Areas [2004-2006 Irrigation Season Study Report] June 2006" Published Primary Industries Research Victoria Environmental Health and Chemistry DPI Werribee. Looked at pesticide and heavy metals monitoring at 15 potential risk sites within six Goulburn Murray Water irrigation areas in northern Vic during 04-05 and 05-06. Five sites were located upstream of water supplies; Katamatite (Channel 7/3), Tatura (Channel 3/5), Corop/Rochester (Rochester Channel Waranga Western Channel), West Boort (Channel 5 Waranga Western Channel).

Positive detections of Atrazine, Endosulfan and Chlorpyrifos. p1 "The CSIRO study recommended monitoring of 10 high risk pesticides in G-MW irrigation channels to establish high risk sites within G-MW irrigation areas. However, both CSIRO and DPI (State Chemistry Laboratory) suggested inclusion of some medium risk pesticides such as endosulfan, atrazine, molinate during pesticide monitoring in channels".

Goulburn Murray Water "Broken Creek Herbicide Residue Testing, 2003-06 Date 1/10/06 Document No: 2034856" Broken Creek supplies drinking water to Numurkah, Nathalia and Wunghu. It is also used for irrigation and drainage services and because it is slow moving and shallow it can be infested with aquatic weeds, especially Arrowhead and Cumbungi. GWM have permits from the APVMA to control weeds in this creek with Glyphosate and 2,4-D (2,4-D has not been used for some years). Positive readings for Glyphosate were detected on 8/5/06 at Thomson Rd, which supposedly is upstream of Nathalia's drinking water supply.

Pesticides Review Committee Minutes 1/3/67 6th Meeting: (d) Mr... informed members of the Committee of a recent incident at Snob's Creek Fish Hatchery, where a pesticide was introduced into the creek 500 yards upstream from the hatchery, which nearly killed approximately 2,500,000 fish. The alternative water supply was introduced in sufficient time to save the fish, which were most stressed...

Agricultural Chemicals Committee (15th meeting 1980?): (I) Waters of Broken Creek. Pollution Control Section of the State Rivers and Water Supply Commission requested analysis of 6 waters from various locations in the Broken Creek near 2 country towns. Trace residues of Dieldrin were detected in all samples 0.01micrograms per litre. A total of 0.16micrograms per litre was present in one sample.

2 December 1981 SRWSC: Sampling of 2,4-D residues Arrowhead Weed Spray Program. "Inspection of Broken and Nine Mile Creeks with EPA representatives 26/11/81. "They did not express their orginal concern about the possibility that the figure of 0.004mg/L for continuous exposure of 2,4-D to aquatic organisms may be exceeded. Their main concern at this inspection was that some verification of our mathematical arguments was now necessary because the use of 2,4-D in a domestic water supply was an extremely contentious issue..."

5 January 1982: Fish kill reported in Drain No. 4 Shepparton. Drain 4 is part of the irrigation system in that it discharges into the East Goulburn Channel 12 which is also a source of domestic supply...A large number of redfin and carp were dead in the Number 4 drain and along East Goulburn Channel 12...numbered well over 200 individuals over 2 to 3 kilometres of the watercourse... A tomato crop on CA34 ... was sprayed some 4 days prior to this investigation by Field Air (Benalla) Pty Ltd ... with Thiodan (Endosulfan) and Copper Cocide...the indications point to an overspray with Thiodan (Endosulfan) and Copper Cocide..."

23 September 1985: Letter to Minister for Health from Yea Water Board about concerns about herbicides and dioxins leaching into the Yea River and wanting advice on water testing.

FoI dates: 1996 to 31/1/07 (Information prior to 1996 not available on any electronic database, and is therefore not readily available.

Sampling done quarterly for potable water systems and twice yearly for non-potable systems.

9 positive samples; 2,4-D, Hexachlorobenzene (4), Pentachlorphenol (2), Heptachlor and one unidentified peaks.

Note: no testing for Atrazine, which Goulburn Murray Water detected at Katamatite (sep 05-mar 06 & oct 06) and Tatura (Jan 05, Apr 05, Dec 06-Apr 06) . Chlorpyrifos also detected by Goulburn Murray Water at Katamatite Jan 06. Endosulfan detected GMW Tatura Nov 05 and Katamatite Sep 05. Note: Positive results for Glyphosate Broken Creek 1/10/06 from Goulburn Murray Water not detected by Goulburn Valley Water tests

Current Pesticide Testing Regimes:

4,4-DDD, 4-4-DDE, 4-4-DDT, Aldrin, BHC (alpha isomer), BHC (beta isomer), BHC (delta isomer), cis-Chlordane, Dieldrin, Endosulfan I, Endosulfan II, Endosulfan Sulphate, Endrin, Endrin aldehyde, Heptachlor, Heptachlor Epoxide, Hexachlorobenzene, Lindane, Methoxychlor, trans-Chlordane, Chlorpyrifos, Coumphanos, Demeton-S, Diazinon, Dichlorvos, EPN, Fensulphothion, Fenthion, Malathion, Methyl Parathion, Monocrotophos, Parathion, Phorate, Prophos, Ronnel, Tetrachlovinphos, Tetrachlovinphos, Tetraethyldithiopyrphos, Trichlorinate, Tukuthion, 2,4-D, Glyphosate, Pentachlorophenol.

Pentachlorophenol is an outdated wood preservative, which may also be formed as a by product of disinfection. Hexachlorobenzene is an outdated fungicide which may also be generated from several sources other than pesticide use. Due to the levels being below guideline levels, no correspondence is known to exist regarding these results.

9.8 Grampians & Wimmera Mallee Water

Chief Irrigation Officer 16/6/67- Weed control, Mallee Town Storages

Lake Whitton: experimental plots. Herbicides Used: Fenae (Fenetrol 45%), Dichlobenil (Casoron 133) (Casoron G), Prefix (2,6,dichlothiobenzamide), TCA (pellets)

Herbicides to be applied to 1/100 acre to control weeds in reservoirs.

Situation: (a) Hopetoun No.2 Storage - Dry 25/5/67. (b) Yarpeet Storage - Dry-Moist 25/5/67. (c) Warracknabeal (Lake Whitton) - Dry Moist 1/6/67.

Chief Irrigation Officer January 1982

Fish kill Hopetoun No 1 Reservoir during October/November 1981 - probably DDT/Endosulfan. "The enquiries indicated a high probability of the fish deaths being caused by insecticides endosulphan and DDT. These chemicals were sprayed from the air by contractos during October to control grubs (Heliothus) in crops such as peas, lupins, sunflowers and tomatoes, and also to control pea weevil. As crops are sometimes as close as five metres to water supply channels, contamination of the water is very likely...There was more aerial spraying than usual in 1981..."

 

Wimmera Mail Times October 27 1986: Dead Yabbies found in "two of the towns four water storgaes and also in dams near Nhill and Pimpinio"

10 November 1986: ADCRC Meeting - "Mr ... reported that the tissue tests on yabbies found dead and dying in three storages around Rainbow showed the insecticide Fenvalerate to be present at 10 parts per billion. However, the channel waters and sediments tested did not show positive results for either Fenvalerate or for the synthetic pyrethroids which were also sprayed, although Fenvalerate was detected in some puddle samples."

20 March 1987 DCFL Memorandum:In October 1986, aerial spraying of field peas for pea weevil and heliotis resulted in extensive yabby mortalities in water stored and farm dams in the Rainbow area. The RWC immediately closed the Rainbor urban storages and took samples of water, sediments and yabbies for chemical analysis. No chemicals were found in water or sediments, but fenvalerate ... was detected at a concentration of 10 parts per million in yabbies...

22 June 1987 Rural Water Corporation (RWC): In 1986 the Rainbow storage was contaminated with insecticide resulting in death of yabbies. The cause was identifed as the aerial spraying of pea crops. DCFL reported 9 other yabbie kills plus one of fish. Subsequent to the contamination of the Rainbow storage no further contamination of any waterway was reported...

21 July 1987: "The Water Commission continues to be concerned that off-target aerial spraying of insecticides or pea crops this year could contaminate water supplies..."

24 July 1987 RWC Memorandum: "... the issue of avoiing potential contamination of water supplies is vital... The urban storages should be highlighted on a plan and the contractors informed that the RWC opposes spraying near flowing channels, storages containing water and within 100m of urban storages..." [Aerial spraying of Wimmera Pea crops].

28 September 1987: RWC Memorandum: The Commission has had recent concerns with off-target spraying of insecticides in the Wimmera and Mallee where urban storages have been polluted. In the present act there is only provision for declaring horticultural areas as hazardous areas, but not waterways or storages...

29 September 1987 Rural Water Corporation

Re: Spray drift from spraying field pea crops adjacent to Rural Water Commission waterways.

"... The seriousness of water contamination was highlighted last year where there was a large yabbie kill in one of the Rainbow urban storages. Fortunately no-ill effects were passed onto the people of Rainbow. The contamination in this case was due to spray drift entering the storage from aerial spraying of a pea crop immediately adjacent to the storage..."

"Last year the urban storage of the RWC at Rainbow was polluted with insecticide from off-target aerial spraying of a field pea crop. There were also other fish and yabby kills in the Wimmera for the same reason..."

29 September 1987 RWC to ADCRC: "You asked to be kept informed of initiatives taken by the RWC to avoid repitition of insecticide contamination of urban storages in the Wimmera and Mallee by aerial spraying..."

October 2 1987: Spray forum Horsham - 200 people attended. In 1985/6 616,000ha of crops and 16,000ha of pasture were sprayed with herbicides. 45,000ha of crops and 8,000ha of pasture sprayed with insecticides.

Time covered in FoI request: 25/6/05 - 20/8/07:

Wimmera Mallee Pipeline being constructed. This will substantially reduce risk of runoff into channels.

Current Pesticide Testing Regimes:

NATA accredited laboratory working on behalf of GWMWater, scan checks for traces of; Lindane, Aldrin, Dieldrin, Heptachlor Epoxide, 4-4-DDD, 4-4-DDE, 4,4-DDT, Hexachlorobenzene (HCB). Testing appears to be based on annual checks however it appears that some supplies are not tested annually and some more than annually. Due to the information sourced from the FoI further explanations are impossible.

No positive results detected.

GWMW also use glyphosate to control weeds in its channel system. "There are no tests for pesticides carried out on water flowing in the channels, since the vast majority of this water is destined for farm dams and non-potable use"

http://www.gwmwater.org.au/sm/weed_spraying.html "Weed Spraying The length of channel treated with chemical weedicides is growing as this form of treatment can defer the more expensive channel ditching in some instances. It is used extensively in the irrigation areas around Horsham where access along channels is a problem, and introduced weeds such as Elodea are rapidly spreading. Generally, GWMWater is responsible for channel waterway areas and the neighboring landholder manages weed control on channel banks and adjacent land."

Most GWMW is sourced from the Grampians and then transported via open channel system. At this stage Friends of the Earth has not assessed any of this infrastructure, much of which is being replaced by pipeline. It is anticipated that the pipeline will lessen significantly issues concerning possible channel pollution, however until an assessment can be made it is likely that open channels will be of some risk in terms of water quality, particularly as a large portion of this region is cropped.

9.9 Lower Murray Water

November 2010: Communities along the Murray River all record 'low levels' of simazine and atrazine over two days. Research in the United States shows Atrazine having impacts at levels as low as 0.1ug/L. Does this mean that the Murray River from Kerang to Mildura, a distance of ~300km was also contaminated with low levels of atrazine & simazine? [3/11/10: Mildura Atrazine 0.02ug/L, Red Cliffs Atrazine 0.03ug/L, Robinvale Atrazine 0.04ug/L, Swan Hill Atrazine 0.03ug/L. Swan Hill Simazine 0.06ug/L.

Time covered in FoI request: 1995 - Nov 06:

Monitoring taken at 9 sites. Samples of raw water for a suite of organochlorine pesticides analyses have been taken on a quarterly basis since 1995. All results of this testing has been reported as less than the detection limits. Since 2005-6, additional testing has been carried out an annual basis to test for additional pestcides, ones that are commonly used in the LMW water supply catchment. These include Atrazine, Chlorpyrifos, Chlorothalonil, Methomyl, Molinate, Maldison & Diuron. These are sampled in place of one of the quarterly OCP samplings. The first sampling took place in May 2006, the second in November 2006 and the third is scheduled for February 2008. All results from the first two samplings were reported as less than the detection limit of 0.03µg/L, with the exception of atrazine in the May 2006 sampling. In May 2006, results for Red Cliffs, Mildura Piangil were reported as 0.03µg/L.

Pollution Control Section - 10 samples taken by Healesville Water Works Trust... The only pesticide detected was Dieldrin in 6 of the samples of the range was 0.02 to 0.06 micrograms per litre).

Time covered in FoI request: 4/2/97 - 25/1/08:

Melbourne Water supply treated water to Yarra Valley Water, South East Water and City West Water (soon also to Westernport Water). Melbourne Water also do testing.

Most of the catchments that Melbourne Water sources its water from are 'closed/protected' catchments. However Sugarloaf Reservoir, commissioned in November 1980, sources its water from the Yarra River, meaning that it is exposed to more contaminants than other reservoirs in the Melbourne Water Network.

Generally speaking almost all water supplied to South East Water does not come from Sugarloaf Reservoir and a large percentage supplied to Yarra Valley Water also does not come Sugarloaf. Water quality from closed catchment sources is likely to be good. For these reasons detailed analysis of South East Water, Yarra Valley Water and City West Water was not carried out, as they rely on Melbourne Water for all testing. Probably less than 15% of Melbourne Water is supplied from Sugarloaf Reservoir.

Positive Pesticide Results:

Johns Hill Plant 7/2/00 (Kallista) for; Aldrin 0.00002 MG/L (100% over guideline value), Lindane 0.00002 (40% under guideline value), Heptachlor 0.000013 (under guideline value).

Johns Hill Plant was supplied via closed pipeline from Silvan Reservoir, which raises the question was the source of the organochlorines Silvan and if so why were the pesticides detected at Johns Hill and not at Silvan?

Heptachlor and Heptachlor Epoxide were also found in sediment, downstream of Reefton in 1996 in the UWRAA study (22).

In mid 2008 Melbourne Water expanded its testing in reservoirs and drinking supply. The additional compounds now tested for are; Hexazinone, MCPA, Triclopyr, Asulam, Glyphosate, Captan, Carbaryl, Chlorpyrifos, Esfenvalerate, Maldison, Mancozeb, Parathion Methyl, Propargite, Simazine, Picloram, Cyprodinil, Metham, Methyl Bromide, Pyrimethanil, 1,3 dichloropropene, Iprodione, Methomyl, Bromoxynil, Metiram, Chlorothanlonil, Chloropicrin. This is in addition to the pesticides already tested for Aldrin, Dieldrin, Chlordane, DDT, Heptachlor, Heptachlor epoxide, Lindane, 2,4-D and Atrazine.

Pesticide Monitoring post August 2010 - also now test for a range of pharmaceuticals and antibiotics:

[~136]

Pesticide Monitoring post mid 2008:

In mid 2008 Melbourne Water expanded its testing in reservoirs and drinking supply. The additional compounds now tested for are; Hexazinone, MCPA, Triclopyr, Asulam, Glyphosate, Captan, Carbaryl, Chlorpyrifos, Esfenvalerate, Maldison, Mancozeb, Parathion Methyl, Propargite, Simazine, Picloram, Cyprodinil, Metham, Methyl Bromide, Pyrimethanil, 1,3 dichloropropene, Iprodione, Methomyl, Bromoxynil, Metiram, Chlorothanlonil, Chloropicrin. This is in addition to the pesticides already tested for Aldrin, Dieldrin, Chlordane, DDT, Heptachlor, Heptachlor epoxide, Lindane, 2,4-D and Atrazine.

A Freedom of Information Request dated 23 June 2009, showed that the improved testing regime detected no herbicides between June 2008-May 2009. Testing appears to be conducted roughly every two weeks at a number of locations (only at Yering Gorge on the Yarra).

In early 2008 Friends of the Earth identified several pesticides of high concern in the Yarra Catchment. Melbourne Water's new testing regimes will only test for four of these substances. The following pesticides of concern will not be tested for; Abamectin, Azinphos Methyl, Dimethoate, Diquat, Endosulfan, Paraquat, Pirimicarb and Thiram.

Pesticide Monitoring 1996-mid 2008:

Two pesticide testings per year for; (Aldrin, Chlordane, Lindane, DDT, Dieldrin, Heptachlor, Heptachlor Epoxide, 2,4-D) + Atrazine since 1/8/05. Most tests carried out at; Cardinia O/L Main, Cresswell Res - Tap on O/L, Dromana 900mm Detention Point, Frankston Detention Pt, Johns Hill Tank Outlet Main, Mornington Detention Point, Silvan Olinda Main Det. Pt, Yan Yean T.P. Detention Point, Yarra Glen Res - Tap on Tank, Winneke Preston Main Research. Pentachlorophenol also tested for?

What this means is that Melbourne Water were only testing for two currently used pesticides.

Melbourne Water have recently had a risk analysis done and a number of agricultural chemicals were identified that Melbourne Water will be doing further research on. They will be focussing on the ten most commonly used pesticides in the catchment. Their study will start in July 2008 (One should wonder why it has taken Melbourne Water 27 years to conduct such a study - Sugarloaf was completed in 1981 and almost no research has been conducted for two decades!)

Sugarloaf Reservoir sometimes supplies South East Water Customers, particularly in drier times. Suburbs include; Albert Park, Balaclava, Gardenvale, Garden City, Fishermens Bend, Elwood, Elsternwick, Melbourne, Middle Park, Prahan, Ripponlea, South Melbourne, South Yarra, Southbank, St/Kilda/West, St.Kilda/East, Windsor.

Pesticide Potential Maps of the catchment upstream of Sugarloaf Reservoir were produced by Friends of the Earth in March 2008. They reveal widespread agricultural land use in the land above the offtake to the reservoir. The Yarra River Catchment upstream of Sugarloaf Reservoir could be one of the most intensively farmed and sprayed regions of any water supply located in Victoria. The catchment (outside of closed catchments) provides more than 1.2 million people with drinking water.

Copies of the maps can be found here and here. Friends of the Earth also claim that the following pesticides should be tested for by Melbourne Water but aren't;

February 24 2008: Tensions Shatter Valley Calm

In the midst of Victoria's water crisis, a neighbourhood dispute over water supplies and the use of pesticides has turned ugly, with allegations of standover tactics and intimidation. A clash between small landowners and two of Australia's largest strawberry growers over the use of pesticides along Woori Yallock Creek has grown to embroil six government departments, the Shire of Yarra Ranges and the police. Water from Woori Yallock Creek drains into the Yarra River, which supplies the Sugarloaf Reservoir and Melbourne's northern and western suburbs. But residents in this picturesque valley in Melbourne's east claim their drinking water and local creek are being contaminated with pesticides, dust and earthworks run-off from neighbouring strawberry farms. They say the dust plumes and pesticide drifts are so bad that they cannot leave their windows open at night. They have started buying drinking water and no longer eat home-grown fruit and vegetables. The residents also claim they have felt intimidated by one of Australia's leading strawberry marketing and distribution companies for raising their concerns about water and air pollution. "There are plenty of residents, including smaller strawberry growers around here, who are intimidated by these people and are too scared to talk about it," said local resident Rob Baines. "There has been a lot of intimidation going on around here, perceived and actual." Mr Baines is leading a campaign to change the farming practices of Oz Fresh Pty Ltd and a Perth-based managed investment scheme, Rewards Group. Mr Baines' property sits alongside the Rewards Group land and is across the creek from Oz Fresh. Tensions increased last week when a confrontation between Mr Baines and his neighbour, Rocco Pignataro, led to complaints to police. "They have been spraying two to three times a week for eight months using turbo sprays that can send the pesticide drifts up to 10 kilometres away, and this is part of the Melbourne water catchment," Mr Baines said. The owners of Oz Fresh — the leading strawberry supplier to Coles and Safeway supermarkets — dispute the residents' claims, citing national food safety awards, regular auditing of farming methods and compliance with laws governing water use in Melbourne's catchment area. But the Labor MP for Gembrook and a member of the Environment and Natural Resources Committee, Tammy Lobato, has asked Melbourne Water to conduct tests in Woori Yallock Creek and the EPA to test drinking water tanks for pesticide contamination. Woori Yallock Creek rises from springs near the base of Mount Donna Buang east of Melbourne and is an important tributary for the Yarra River and the Melbourne water catchment. Rights to pump from the creek or collect surface run-off in the catchment require a licence from Melbourne Water. The long-established Oz Fresh farm, recently expanded to cover 97 hectares, has entitlements to pump from the creek and store water for irrigation. But the Rewards Group, which started to acquire properties in the valley 10 months ago and has contracts and lease arrangements with Oz Fresh, has not been granted a water licence. Despite this, Rewards' strawberry and blueberry farm is being promoted to investors as having access to millions of litres of Melbourne's drinking water from "river diversion licences" and a 200-megalitre storage dam to be constructed within six months. "What they say on their website is one thing; we do not have an application (for the dam)," said Melbourne Water spokesman Ben Pratt. "Oz Fresh have a 138-megalitre entitlement that is surface and water allocations (creek pumping), but bans on pumping are current." Mr Pratt said Melbourne Water had been working with Oz Fresh and Rewards Group to develop a farm management plan that would include revegetating the banks and public reserves along their shared creek frontage. He said no new water rights would be approved until Melbourne Water was satisfied the environmental and water management plan had been fulfilled. "We are closely monitoring the activity of Oz Fresh to ensure they comply," Mr Pratt said. But Joe Pignataro, a director of the private, family-run company, said the Woori Yallock property had award-winning farm practices. He denied any suggestion the neighbours were intimidated by his family and said "my door is always open". "I have no idea why they would be saying these things," Mr Pignataro said. He also denied pesticides were sprayed on his property with booms raised, a practice known to contribute to spray drift. "There is no issue with pesticides," he said.

April 29 2009: Melbourne seeks water from NSW (by Peter Hunt Weekly Times)

Melbourne Water has investigated buying water out of NSW this season, according to a senoir government source. The city water corporation "sounded out" some water brokers to determine what options they had, despite the Victorian Government repeatedly declaring it would not buy water to supplement Melbourne's needs. A spokesman for Melbourne Water denied the corporation had ever examined the option. However other water corporations, such as Coliban Water have already purchased seasonal allocation water from NSW Murrumbidgee irrigators to supplement Bendigo's supplies. Coliban Water is able to buy Murrumbidgee allocations to replace water supplied by Lake Eildon to Robinvale and Sunraysia irrigators. The water is then freed up in Lake Eildon to supply Bendigo, via the Western Waranga channel. Melbourne Water has investigated using exactly the same process to supply water via the north-south pipeline. Until the end of March, NSW State Water processed a record net transfer of 385,580 megalitres from NSW to South Australia and Victorian irrigators and government agencies.

 

Sugarloaf Treatment

Source: http://www.melbournewater.com.au/content/publications/fact_sheets/water/winneke_treatment_plant.asp

"The treatment process

The function of the Winneke Treatment Plant is to produce drinking water that meets water quality guidelines set by the National Health and Medical Research Council.

Water treatment involves a number of processes: coagulation; clarification; filtration; disinfection; and fluoridation.

Coagulation: raw water is pumped from the reservoir to the Winneke Treatment Plant inlet control structure, where it is mixed with liquid aluminium sulphate (alum). The alum acts as a coagulant encouraging suspended solids and microorganisms in the raw water to bind together to form larger particles.

Clarification: the water then flows through an underground channel to a water distribution chamber that feeds the four clarifiers. Water is detained and circulated in the clarifiers for about three hours. The clarifiers enhance the cohesion and entrapment of the suspended solids and remove colour from the water. Solid particles are separated from the raw water producing what is termed 'settled water' and sludge.

Filtration: the 'settled water' is delivered through concrete channels to 12 gravity filters, which remove most of the remaining suspended solids. Each filter is a rectangular, concrete structure with a bed of sand supported by a layer of course media that is supported on a layer of pebbles.

Disinfection and pH correction: after the water passes through the filters, it is disinfected (by chlorination) to destroy residual microorganisms. Lime is added to adjust the alkalinity/acidity (pH) level. The fully treated water flows into a large enclosed storage reservoir adjacent to the treatment plant. This reservoir is a buffer storage and water is supplied from it as required.

Fluoridation: Melbourne Water is required by State Government legislation under the Health (Fluoridation) Act 1973 to fluoridate the water supply. Fluoride is added in precise quantities downstream of the Winneke Treatment Plant at Research."

According to the Victorian State Government report; Our Water (2004), "Appendix 6 Winneke Water Treatment Plant upgrade requirements"; p1 The Winneke Water Treatment Plant (WTP) is a conventional treatment plant utilising coagulation and flocculation, upflow clarification, rapid granular media filtration, and chlorination ... p3 Note" There is no Powder Activated Carbon (PAC) at the plant. MWC has considered future UV and Ozone/GAC (Granulated Active Carbon), but these are not part of the current WTP...p4 MWC has a program of protozoa and pesticide monitoring and modelling to determine whether enhanced risk management is required for Winneke WTP. Currently, Ozone/GAC filters are scheduled for 2017, subject to justification of need based on the above work. If Ozone/GAC filters are installed in the future, the proposed PAC dosing and UV plant will become redundant. However, this would still minimise NPC, as bringing forward the ozone/GAC would be double the cost of the PAC/UV installation".

Past studies of the Yarra Catchment (re: Pilot Survey of pesticide levels in water and sediments of streams in agricultural catchments (Publication No:142 March 1982 Water Quality Branch Environment Protection Authority) showed that pesticides were detected at a site just downstream of Yering Gorge. Yering Gorge is significant as a pumping station was built soon after the study was completed in order to supply the newly constructed Sugarloaf Reservoir. Organochlorine pesticides detected downstream of Yering Gorge in 1980 included DDE @ 0.01µg/L, DDT @ 0.01µg/L and 0.007µg/L, Dieldrin @ 0.02µg/L, Lindane @ 0.002µg/L, 2,4-D @1.1µg/L and the insecticide Malathion @2.6µg/L. Sediment at the site showed DDE @ 0.02µg/L and 0.01µg/L. Dieldrin was also detected in the sediment in 1981 @ 0.01µg/L. It is most likely that these pesticides were washed down the Yarra from agricultural practices further up in the catchment. Taking the following data from the latest ADWG, guideline value for DDT is 0.06µg/L, health value is 20µg/L. Guideline Value Dieldrin 0.01µg/L, health value 0.3µg/L. Guideline Value Lindane 0.05ug/L, health value 20ug/L. Guideline Value 2,4-D 0.1µg/L, health value 30µg/L. Health Value Malathion (Maldison) 50µg/L.

Dieldrin therefore was detected at twice the future guideline limit and 2,4-D 11 times the future guideline limit. The Malathion level was just over 5% of the future health limit as no guideline limit is granted for this insecticide, but well under the ADWG Health limit. It is not impossible that not only could pesticides be detected at the Sugarloaf pumping station, but that they could be pumped into Sugarloaf Reservoir and it appears bizarre that Melbourne Water basically discontinued future testing until well into the 1990's.

In 1982 a further study into Macroinvertebrates of the Yarra River; stated in regards to Wandin Yallock Creek that "pesticides appear to be the most likely toxic influence at this site. TDE, DDE, DDT and Dieldrin have been detected in the sediments at a site 2km downstream of a major market gardening and horticultural area, and DDT and Dieldrin have been found in the sediments of a site in the middle of the market gardening area...TDE, DDE, DDT and Dieldrin have been detected in sediment samples 8km downstream of areas of intensive market gardening and potato growing..." (30)

Another study (31) published in 1983 looked at pesticide transport in three sub catchments of the Upper Yarra Catchment. The pesticides Diedrin, DDT, DDE, Linuron and 2,4,5-T were detected. Pesticides at one location were most frequently detected in flows during vegetable washing operations. Pesticide concentrations were also generally higher in storm flow samples. Pesticide loads transported from catchments were generally between 1.3 and 9.3 mg/ha and between 134 and 228mg/ha in relation to vegetable washing plants. The authors wrote; "The concentrations of Dieldrin and DDT do not appear to present problems for drinking water supply in the Yarra River itself although, on occassions the concentrations detected in flows from cultivated land during storms and operation of vegetable washing plants exceeded health criteria".(31).

It could be argued that if vineyards are included, the current amount of intensively sprayed agriculture in the Upper Yarra Catchment is in 2008, 9000ha+, a 1000% increase on the 870ha intensive cropping figure quoted in the above study, potentially meaning higher pesticide volumes at a catchment level, also potentially meaning higher levels of pesticide loads transported from catchments, depending on the pesticide and site conditions.

Melbourne Water also conducted research in contamination of sediments at several locations in the Yarra River catchment in 1996. Study looked closely at heavy metals and PAH's (Polycyclic Aromatic Hydrocarbons). The pesticides tested for included; BHC, dichloran, Lindane, Heptachlor, Heptachlor Epoxide, Chlorpyrifos, Chlordane, Endosulfan, Dieldrin, DDT, Methoxychlor & Dicofol. Upstream of Sugarloaf Reservoir pesticides were detected at one location, downstream of Armstrong Creek Reefton; BHC 5ppb/kg, Dichloran 10ppb/kg, Lindane 5ppb/kg, Heptachlor 7ppb/kg, Heptachlor Epoxide 20ppb/kg. Highest readings for pesticides in the Yarra were located at testing sites at Glen Iris, Clifton Hill, Blackburn, Park Orchards.

EPA have very little information concerning impacts of pesticides above sugarloaf offtake. For instance there are 4 current water discharge licences for Olinda Creek, 2 relate to sewage treatment and 2 relate to extractive industry and mining, including Unimin Lime who have not met its statutory obligations to the EPA auditor in 2006.

Time covered in FoI request: 2003 - 3/1/08

Up to 2004 North East Water were testing for; 2,4-D, 4,4-DDT, Aldrin, Dieldrin, Heptachlor Epoxide, Heptachlor, Hexachlorobenzene, Methoxychlor, Pentachlorophenol, Trans Chlordane.

No testing was carried out from 2004 until January 2008, except isolated tests for hexazinone in late 2007. No positive results.

Testing resumed for a range of pesticides (most organochlorines in January 2008 The Australian Drinking Water Guidelines (2004) state that "Routine monitoring for pesticides is not required unless potential exists for contamination of water supplies". Perhaps by using this clause NE Water decided to stop testing in 2004.

Past studies Ovens River (Wangarrata's Water Supply)

In “Organochlorine Pesticide Residues in Water & Sediments from the Ovens and King Rivers, North East Victoria, Australia F. McKenzie-Smith, D. Tiller, D. Allen EPA Victoria, State Chemistry Laboratory Published in Arch. Environ Contam. Toxicol. 26, 483-490 (1994)” , the highest reading for DDT (and its metabolites) at a site just upstream from Myrtleford on the Ovens River was 0.34µg/L recorded during a storm event, with Dieldrin recorded at much lower levels. Downstream of Myrtleford DDT measured at ~0.051µg/L and Dieldrin 0.0026µg/L

In “Biocide Contamination in the Aquatic Environment. A study of the Ovens and King Rivers Region. EPA Scientific Series SRS 90/004”, the highest reading for DDT in a storm event on the Ovens River was 3.8µg/L . Dieldrin was found on the King River during a storm event at 0.07µg/L", Aldrin at 0.01ug/L, Lindane at 0.01µg/L and Heptachlor at 0.08µg/L. Total DDT levels in sediment at a Myrtleford site were as high as 70ug/kg and at Edi on the King River at 85ug/kg. Total Dieldrin levels at Porkepunkah were found at 5ug/Kg and at 10ug/Kg at Edi. These levels are of concern.

 

9.12 South East Water

Silvan Dam, on the eastern side of the Dandenongs. Dicamba detected at Wantirna (April 2016) should have been first detected here first. Silvan is supplied by aquaducts from reservoirs in the Upper Yarra.

Purchases water from wholesaler Melbourne Water and distributes that water throughout South Eastern Melbourne region. Started widespread testing for pesticides in 2014.

From the uppermost catchments, water flows into Thomson and Upper Yarra Reservoirs where water may be stored for many years before being used. Holding the water for a long period allows the sediments from the forests, washed in by the rain, to settle, providing natural purification. Water from the upper reservoirs is then transferred to Silvan and Cardinia Reservoirs. Upon leaving the reservoirs, it is disinfected by using chlorine to kill potentially harmful micro-organisms and maintain public health. The water is also fluoridated and corrected for pH.

Positive Detections: Thiobencarb 0.02ug/L (Webb Street, Bunyip), 2,4-D 0.02ug/L (Jaguar Drive Clayton 15/8/14), 2,6-D 0.02ug/L (Jaguar Drive Clayton 15/8/14), Dicamba 0.01ug/L (Merryn Grove Wantirna 18/4/16).

This is significant as it reveals that treatment used by Melbourne Water will not eliminate all traces of pesticides. Water sourced from Wantirna is from Silvan Dam

9.13 Southern Rural Water

Kentucky Creek Gippsland (Maffra/Stratford Water Supply), flushed with the herbicide Acrolein 2005

Time covered in FoI request: 2005 - 20/10/06

SRW operates four specific surface water supply systems:

- Werribee system (Merrimu and Pykes Creek Reservoirs)

-Rosslynne Reservoir

-Thomson/Macalister system (Lake Glenmaggie and Cowwarr Weir)

-Blue Rock Lake

SRW does not supply drinking water, it supplies untreated raw water to its water suppliers (Western Water and Gippsland Water). SRW does not use chemicals, substances or any process to disinfect or treat the water that we supply for drinking purposes. Blue green algae has been a problem in recent years.

SRW used Acrolein to kill aquatic weeds in January and November 2005. Monitoring was carried out. Highest readings; 8/11/05 Football Lane 6560µg/L, 18/1/05 @ 80 Foot Drop 5908µg/L. Domestic supplies may have been impacted as spraying occurred upstream of Maffra/Stratford's water supply. Unsure of exact locations of spraying.

Southern Rural Water also use herbicides to control weeds; "Where use is likely to occur adjacent to a waterway, SRW only utilises chemicals such as Round-up Biactive" According to SRW Chemical Control Procedure, Spray Chemicals used by SRW include Round Up - Biactive (herbicide), Trounce (herbicide), Amitrole (herbicide), Wetter TX (surfactant) and Pulse (surfactant). Weed control Blackberrys; Trounce + Wetter TX (10g/Kg Metsulfuron)(835g/Kg glyphosate). Weed control Cumbungi; Roundup Bi-active (Glyphosate as the isopromlamine salt [glyphosate-N-(phosphonomethyl)glycine], Wetter TX Weeds and grasses; Roundup Bi-active.

June 1 2007: SRW Tests Show Chemicals

TESTS have confirmed the chemical acrolein has been detected in the Thomson River after being used as a weed killer by Southern Rural Water. The chemical is used to kill submerged weeds in SRW's main southern and main northern channels. Freedom of Information documents obtained by the Gippsland Times show levels of almost three parts per million were recorded at a site referred to by the test papers as "Heyfield Intermittent Town Supply". A reading of more than four parts per million was detected at the point referred to as "Swimming Pool Check". Both sites were tested as part of the main southern channel. In the main northern channel, readings of five parts per million were recorded at sites referred to as "Football Lane" and "Coloe's Road". The testing was carried out by SRW following use of the chemical. The SRW response to the FOI request also states SRW "does not routinely monitor chemicals within its water supply networks" as it is not required to by law. Victorian Agricultural Chemicals Advisory Committee representative Anthony Amis questioned what arrangement SRW had with regard to alerting water authorities of the chemical treatments and sought assurances the chemicals could not enter the water supply for Maffra via the Macalister River. While he admitted acrolein had a relatively short half life of around two days, he said the chemical had been the subject of a fish kill investigation in the Goulburn River - an irrigation district. "Fingers were pointed at use of acrolein which is highly toxic to fish," he said. "There was a report done by the EPA." SRW also uses roundup as a form of weed control. Tests for glyphosphate came in below the detection limit, according to the FOI document. An SRW spokesperson had not responded to request for an interview at the time of going to print.

Strzelecki Ranges - Hancock plantation logging Tarwin River headwaters

Korumburra Golf Course surrounds this Ness Creek storage. What pesticide applications are applied here? It has apparently been a concern for over 30 years with 2,4-D and Iprodione likely to be course "favourites".

49 pesticide detections between 2012-2016. 88% of detections for Triclopyr. Most frequent detections at Toora (10), Meeniyan (9), Dumbalk (8), Foster (6), Korumburra (5).

On 21/4/2015 Triclopyr was detected at 2.6ug/L at Toora, the fourth highest level of Triclopyr recorded in an Australian domestic water supply.

16/6/67 Letter from SRWSC to Korumburra Waterworks Trust: "The Korumburra Waterworks Trust recently drew to the attention of this Commission the establishment of a private airstrip on land adjoining the catchment area of the Korumburra Reservoir. The trust has reported that the airstrip is being used by operators for aerial spraying purposes and has expressed concern as the direction of take-off for aircraft, on account of the surrounding hills, is directly over No.3 Reservoir... The Department of Civil Aviation has advised that the airstrip in question is not a licensed aerodrome and it therefore has no control over the use to which it is put...

Minutes Pesticide Review Meeting #141Committee Victorian Government 6/10/78: "(d) Letter from Korumburra Waterworks Trust. The letter from the Trust and a copy of the Latrobe Water Sewerage Board about the proposed use of Weedicide Estan 80 (2,4-D) on the Korumburra Golf Course in close proximity to the towns No.1 reservoir was tabled. Dr Parsons felt that an amine formulation would be preferable to estan and that care should be taken as to weather conditions existing at the time of spraying eg windless and rainless. Dr Christophers said that as the town's water supply could be involved the matter should be referred to the Health Department with certain recommendations from this committee for examination and advice."

Minutes Pesticide Review Committee Victorian Government 19/7/1979: "...Request from Korumburra Golf Club to use the Turf Fungicide 'Rovral' (Iprodione). The Korumburra Golf Course is in the direct catchment of the towns water storage reservoir and runoff reaches the reservoir very quickly due to the drainage of the greens and fairways".

Letter from Korumburra Waterworks Trust to PRV August 18 1981: "Korumburra Golf Course catchment No.1 Reservoir is owned by the Trust and leased to the golf club. Water run-off from the golf course goes directly into the town's water supply reserve. Selective herbicide required to control English Daisy. Suggested that MCPA and Dicamba be used. "The reservoir has already given some trouble and has been the subject of a report by the Materials Science Division of the SRWSC on various algae and biological problems which have affected water, taste and colour..."

March 10 2010: Growing Pains (E. nitens plantations potentially toxic)

Susie points to a broad bank of plantation nitens: ''They're in my catchment,'' she says. The trees grow next to a creek, which funnels into Middle Creek - the brook that runs past Susie's house. ''The issue is very dear to my heart because I suffer from multiple chemical sensitivities, which is why I live where I live, away from most people and most pollutants, so it's something of great interest to myself and any other person who uses the water,'' she says. Susie pumps water out of the river for domestic uses such as bathing. She's capturing rainwater for her drinking supplies, but there's plenty of others around Gippsland who are drinking from rivers that also sustain nitens plantations. On the south side of the Strzeleckis, Margaret and David Pellew hire out a small number of forest cabins on the banks of the Tarra River. The Tarra supplies drinking water to the Pellews and nearby towns such as Devon and Yarram, as well as sustaining nitens plantations. The Pellews were already aware of the Tasmanian controversy when The Age visited this week. ''We're concerned and we would certainly like to know more about it. We'd like to know scientifically how it affects the water,'' says Margaret. Plantation company Hancock says its nitens crop covers about 5600 hectares of Gippsland. Most of those nitens are grown in pockets across the Strzeleckis, but there are also some planted in the Great Dividing Range north of Noojee. The company withdrew its original offer to allow The Age access to its plantations, but in an email Hancock spokesman Steve Wentworth said the company was aware of the Tasmanian controversy.

As people such as the Pellews start to ask questions, local water authorities, at the instruction of Victoria's Health Department, do not seem interested in chasing answers. South Gippsland Water, the authority which harvests the Tarra River for Yarram's supply, says it will not be initiating any investigations. ''We are in contact with [the Health Department] regarding this issue and as yet have received no advice to carry out further water testing,'' spokeswoman Ros Griggs says. ''South Gippsland Water will be waiting for advice from our health regulator regarding any additional requirements.'' Neighbouring authority Gippsland Water confirms that the town of Seaspray is drinking from a river catchment that sustains nitens, but spokeswoman Leah Mether says there will be no change to testing regimes in the short term. ''Gippsland Water treats all its water supplies to ensure compliance with the Safe Drinking Water Act, and has not received any advice from the Victorian Department of Health to alter these existing treatment methods,'' she says. The Victorian Health Department regulates drinking-water safety in this state, and spokesman Bram Alexander says there does not appear to be any danger to Victorian water supplies. ''We are looking at this issue closely. Based on available evidence, it is too early to draw any conclusions. However, from our regular monitoring of water quality in those two water authorities, there is nothing to suggest drinking water supplies are unsafe,'' he says. Alexander declined to clarify whether ''looking at the issue closely'' meant the department was running its own tests on Victorian water, or merely reading the Tasmanian newspapers.

Current Pesticide Testing Regimes:

Testing on an annual basis each March in the following zones; a) Alberton/Pt Albert/Yarram/Devon North, b) Dumbalk, c) Fish Creek, d) Foster outlet and after trim dosing (Mar 07), e) Korumburra, f) Leongatha/Koonwarra, g) Leongatha After trim dosing (Mar 06 & 07), h) Meeniyan, i) Meeniyan (after trim dosing) Mar 06 & 07, j) poowong/loch/nyora, k) toora/Welshpool, l) Wonthaggi/cape paterson/Inverloch, lance creek before trim dosing.

Kerrie Reservoir (Water supply for Romsey) located in the Bolinda Creek Catchment ~6km south west of Romsey. This water supply had traces of the herbicide 2,4-D detected in it in February 2007 0.02ug/L and 2010 0.04ug/L. 2,4-D was also detected at the Glenfern Park Basin (just out of Romsey) in 2007 0.04ug/L and 2010 0.02ug/L. Most of the Bolinda Creek catchment has native forest and pasture on it, meaning that a farmer had most likely been using 2,4-D and some of this was washed into the reservoir. Low levels of 2,4-D also detected at Merrimu Reservoir (Bacchus Marsh) 6/2/07 0.01ug/L, Djerriwarrah Reservoir (Melton) 6/2/07 0.02ug/L and 9/2/10 0.02ug/L, Garden Hut Reservoir (Lancefield) 8/2/07 0.05ug/L, Pierce Reservoir (Gisborne) 10/2/10 0.01ug/L, Pykes Creek Reservoir (Myniong) 6/2/07 0.06ug/L, 11/2/08 0.03ug/L, 8/2/10 0.04ug/L, Wright Reservoir (Riddells Creek) 20/2/08 0.01ug/L.

The most serious pesticide drinking water quality issue occurred at Willimingongon Reservoir (Mt Macedon) 10/2/09 with a detection of Pentachlorophenol at 3.8ug/L. This incident ranks as the 8th most serious pesticide incident in Victoria since 2003. Were residents informed?

Candowie Reservoir - 100 ha tree plantation to be planted 2008. This particular plantation is controlled by interests closely associated with notorious Malaysian timber company, Rimbunan Hijau. herbicides are used in tree plantations for the first 2-3 years of plantation establishment. This can increase risk of pollution into waterways. Aerial spraying of plantations also a possibility if plantations come under insect attack. Monocrotophos has been stem injected into eucalypts to control insects elsewhere in Australia.

Monocrotophos, a banned insecticide detected in Candowie Reservoir 6/12/11 at 20 parts per billion. That's 20 times over the 2004 Australian Drinking Water Guideline. The most serious pesticide incident in a Victorian water supply since the 1970's. Monocrotophos has been deregistered fir use in Australia since 1999, yet 12 years later was detected in Candowie Reservoir. "Cancelling the active constituent approval and its importation, with effect from 9 December 1999 cancelling all product registrations, with effect from 9 December 1999".

Supply water to Phillip Island and mainland from The Gurdies to Archies Creek.

Candowie Reservoir, San Remo Service Basin, Cowes (Reticulation), Rhyll (Reticulation). Tested for chlorinated pesticides quarterly 20/7/92 - 28/1/93, half yearly 24/1/94 - 20/1/95, quarterly 20/1/95 - 16/4/04. Also broad spectrum of pesticides tested for at Tennant Creek in May 2002. No Positive Results. It appears that Westernport Water no longer test for pesticides, probably due to the Safe Drinking Water Act - re ADWG quote. However due to pressure from Friends of the Earth, Westernport Water announced in April 2008 that testing would resume again.

Press StatementWesternport Water August 2008:

'Water flowing into the Tennent Creek and Bass River from neighbouring farmland will be checked for micro-organisms before it gets treated for human consumption. Water quality officer Dean Chambers said: “Two specific tests, for giardia and cryptosporidium, are linked to livestock effluent – particularly from young cattle. Calving season has almost finished and we have timed these new tests to monitor raw water quality off farms.

“We have already instituted regular testing for herbicides and pesticides. Now we will be also testing for naturally occurring radiation – some types of rocks emit local levels of radioactivity – and we will include those measurements in our monitoring. “All our initial tests have shown none of these factors exceed recognised safety standards, but we will continue our tests every month for 12 months.”

Dean said the water corporation will test raw water quality after major rainfall events, and will also check water pumped from the Bass River and nearby bore fields before it is introduced into Candowie Reservoir. Acting Managing Director Keith Gregory said: “We are now tracing water quality to source. “The water supplied to our customers has always been treated to recognised health standards, but now we are taking quality one step forwards … by going backwards up the supply chain.” The move to broaden the range of raw water testing follows an independent, state-wide audit of water quality risks and testing procedures, organised by the Department of Human Services. “The tests we undertook following the Westernport Water audit gave our water the all-clear,” Mr Gregory said. “We are seeking to maintain that good record.”

Westernport Water will continue working in co-operation with local landholders, Landcare and Melbourne Water to protect and enhance riverside systems in the corporation’s distribution area, he added.

Corinella groundwater a potential supply of water in the future. Westernport Water plan to be connected to the Melbourne Water system in the near future via a 44km pipeline. Water from the Bass River also started be pumped into Candowie from July 2007. Agricultural activities, in particular Dairy will be an issue in the Bass River Catchment. Bore water from Grantville also used in 2007. Candowie also connected up to Lance Creek Reservoir (South Gippsland Water).

10. Water Treatment

Following information sourced from; Office of Pesticide Programs Science Policy - The Incorporation of Water Treatment Effects on Pesticide Removal and Transformations in Food Quality Protection Act (FQPA) Drinking Water Assessments October 25, 2001. Office of Pesticide Programs United States Environment Protection Agency Washington, D.C. 20460.

p5 "EPA's preliminary review of the literature indicates that conventional treatment (such as coagulation/flocculation, sedimentation and filtration) has little or no effect on the removal of mobile (hydrophilic or lipophobic) pesticides. Disinfection and softening can faciltate alteration in the chemical structure of the pesticide, or transformation..."

p11 "Disinfection and water softening...can...lead to pesticide transformation and, in some cases, pesticide removal or degradation. This finding is important because disinfection and coventional coagulation/filtration are commonly used treatment processes Community Water Systems (CWSs) in the United States."... "Powdered activated carbon (PAC) filtration, granulated activated carbon (GAC) filtration, and reverse osmosis (RO) have been demonstrated to be highly effective processes at removing organic chemicals, including certain pesticides (primarily acetanilide herbicides), but specific data on removal of most pesticides are not availaible. Also, air stripping is only effective for volatile pesticides or those with a high Henry's Law Constant. Among these organic removal treatment processes, PAC is the more common method because it can be used in concert with conventional water treatment systems with no significant additional capital investment..."

p13 Granular activated carbon (GAC), under the SDWA (Safe Drinking Water Act) is the best available technology (BAT) for removing synthetic organic chemicals (SOC); virtually all pesticides are SOCs. Other recommended BATs are aeration technologies for removal of dibromochloropropane and chlorination or ozonation for removal of glyphosate.

p14 ...The European Union (EU) has issued the drinking water directive of 1998 that sets a maximum concentration of 0.0001mg/L for individual pesticides or degradation products and 0.0005mg/L for total pesticide residues in drinking water after treatment (Acero et al, 2000, http://europa.eu.int/water/water-drink/98_83en.pdf).

p19 "Organic compounds potentially removes through coagulation/flocculation are hydrophobic, low molecular weight acidic functional groups (eg., carbonyl and carboxyl functional groups), or high molecular weight compounds".
