What is PFAS?
Per and poly-fluoroalkyl substances (PFAS) such as PFOS and PFOA are a group of manufactured chemicals.
PFAS have been used since the 1950s in a range of common household products and specialty applications, including in the manufacture of non-stick cookware, fabric, furniture and carpet stain protection applications, food packaging, and some industrial processes including certain types of fire-fighting foams.
However the substances are not manufactured in Australia and are no longer directly used in consumer products.
National health-based guideline values have been established for PFAS in drinking water. These guideline values are very low, and are based on an assumption of lifetime consumption at the maximum tolerable daily intake. PFAS are found at very low levels in the blood of the general population all over the world.
