2005 October: Sunday Creek Reservoir. Pesticide detected: Pentachlorophenol.

Sunday Creek Reservoir supplies drinking water to the towns of Broadford, Kilmore and Kilmore East. Traces of Pentachlorophenol (PCP) at 2 µg/L (2 parts per billion) were detected in this reservoir in October 2005 by Goulburn Valley Water. The reading came in at 20% of the Australian Drinking Water Guideline.

Pentachlorophenol is a chlorinated phenol and is a carcinogen, a suspected endocrine disruptor and has a high acute toxicity. The World Health Organisation class Pentachlorophenol as 1b (Highly Hazardous). PCP is known as being a wood preservative, a microbiocide, an algaecide, a fungicide and a molluscicide. So what is it doing being detected in this reservoir which has a largely closed catchment.
