Per and Poly-Fluoroalkyl Substances (PFAS)
PFAS chemicals or per- and poly- fluoroalkyl substances are synthetic chemicals found in many everyday products. They have been widely used in many industrial and consumer applications as they are effective at resisting heat, stains, grease and water. The National Health and Medical Research Council (NHRMC) has stated that drinking water supplies that comply with the current Australian Drinking Water Guidelines (ADWG) are safe to drink.
For further information about PFAS please refer to the fact sheet from the Water Services Association of Australia (WSAA): Per- and Poly-Fluoroalkyl Substances (PFAS) Fact Sheet
Council undertakes a regular sampling program of source and treated water for PFAS in accordance with the ADWG and NSW Health requirements.
The 2025 PFAS sampling results conducted by a National Association of Testing Authorities (NATA) accredited laboratory are presented below.
Due to elevated concentrations of PFAS within one of Narromine's source water bores, monthly PFAS sampling is currently in progress.
Tomingley and Trangie potable water systems have annual PFAS testing.
Council's treated drinking water is safe to drink and within Australian Drinking Water Guidelines.
