PFAS (per and polyfluoroalkyl substances) are a group of human-made chemicals that have been widely used in industrial and consumer products since the mid-1900s.
Use our guide below to find answers to common questions about what is PFAS and how we monitor for it across our water treatment systems.
PFAS (per and polyfluoroalkyl substances) are a group of human-made chemicals that have been widely used in industrial and consumer products since the mid-1900s. The Australian Government’s Environmental Health Standing Committee (enHealth) continues to recommend exposure to PFAS be minimised wherever possible.
TasWater monitors PFAS levels across all of our raw water catchments that supply our 58 Drinking Water Systems, conducting more than 7,300 tests since May 2024. Throughout this period, no exceedances of health-based ADWG limits have been recorded.
