Yarra River Catchment Maps 2

Upper Yarra River Catchment Maps March 2008

Drinking Water Supply for 1,200,000+ people.

9000+ hectares of Melbourne's Water Supply heavily sprayed with a range of pesticides. Most spraying occurs within 20km of Sugarloaf Reservoir.

What are the Chemical Loads and why does Melbourne Water only test for two currently used pesticides (2,4-D and Atrazine (since 2006))?

Main pesticides of concern to Melbournians would probably be; Parathion Methyl, Paraquat, Diquat, Simazine, Chlorpyrifos, Carbaryl, Methomyl.

Also of concern to people and health of Yarra River and tributaries would probably be; Mancozeb, Paraquat, Diquat, Maldison, Thiram, Metiram, Pirimicarb, Triclopyr, Methomyl, Ipriodione, Dimethoate, Captan, Endosulfan, Abamectin, Propargite, Azinphos Methyl & Esfenvalerate.

What about the hundreds of other pesticides used upstream of the offtake to Sugarloaf Reservoir?
