Sydney Water did not perform “an appropriate level of due diligence” before claiming there were no known Pfas hotspots within its drinking water catchments, a state parliamentary committee has found.

The New South Wales upper house committee tabled its 16 findings and 32 recommendations on Thursday following an inquiry triggered by reporting in the Sydney Morning Herald that detected elevated levels of some “forever chemicals” in parts of Sydney’s drinking water catchment.
