2004-6: Brisbane Pesticides in Water Tank. Pesticide: CPA

Pesticides, fungicides and herbicides
A range of pesticides, herbicides, fungicides and pyrethroids were tested. Each laboratory tended to have their own suite of chemicals tested which lead to only partial consistency between laboratories. Of the range of chemicals tested there was only one tank from the second sampling in Brisbane that detected the herbicide CPA (4-chlorophenoxy acetic acid) at a level of 366μ g/L in tank water. The same tank did not have any present in the first round of testing. Brisbane was the only location that tested for CPA so this result is out of 11 samples in total that were tested for CPA. All other samples from all locations did not detect any chemicals of this class.
