2002 September: Orbost Water Supply. Pesticide Detected Simazine

10 September 2002 Simazine Testing Rocky River, Murrungower (Orbost Water Supply East Gippsland, Victoria)

Letter to Harris Daishowa from East Gippsland Water

“As discussed with you, the initial tests (4th June 2002 pre-spraying) returned a result of <0.02ug/L however, Simazine was detected at a level of 0.2ug/L in the post spraying sample taken on 7th August 2002… Given that the sampling program was limited to a single standard before and after spraying events and no further investigations had been undertaken upstream of your site or at sites inbetween Murrungower and our offtake, it can only be assumed that the source of contamination was the spraying activity…”
