Pesticides detected: Denham (WA)

2006 August 23: Bifenthrin 0.08ug/L

Denham – the water source for Denham is two brackish artesian bores which are desalinated prior to distribution to customers. The bores draw water from a deep, protected aquifer so the risk of source contamination from pesticides is low. Bifenthrin is an insecticide and the source of the contamination from the sample taken on 23 August 2006 was not able to be identified. A subsequent sample on 6 September 2006 did not detect bifenthrin and it has not been detected in any samples since.
