1999-2000:

The detection of atrazine and hexazinone in product water from the Barossa Treatment Plant, atrazine, in product water from the Hope Valley Treatment Plant (0.5ug/L), dieldrin in Mt Bold Reservoir (0.07ug/L) and the concentrations of hexazinone detected in the Little Para River (5.9ug/L) and the River Murray at Mannum (2.5ug/L) [atrazine also detected at Mannum March 8 2001, 0.5ug/l] and Lock 9 (2.1ug/L) represented Type 1 incidents. However, the concentrations detected were well below the health related guideline values (atrazine 20ug/L; dieldrin 0.3ug/L; hexazinone 300ug/L) and DHS considered in each case that there was no risks to human health. Except for the results from the Barossa Treatment Plant the pesticide detections were gnerally isolated samples.

The remaining detections represented Type 2 incidents.
