"This is absolutely heartbreaking ... Think about it next time you purchase a 3M product," Ms Brockovich wrote on Facebook, linking to the original Fairfax Media story. The report released overnight showed that PFAS chemicals in public water supplies around the country are threatening human health at concentrations seven to 10 times lower than previously realised. The New York Attorney-General launched legal action against 3M and other manufacturers of perfluoroalkyl and polyfluoroalkyl (PFAS). They were used in goods such as fire-suppressing foam, non-stick pans and fast-food wrappers. New York Attorney-General Barbara Underwood.

A January email from a White House official, released under the Freedom of Information Act, refers to it as a "potential public relations nightmare".

Both the Oakdale and Williamtown areas had contaminated drinking water. There are now at least 90 sites in Australia under investigation for contamination, Fairfax revealed. New York Attorney-General Barbara Underwood said corporations needed to be held to account for contaminating water supplies. "We are filing a landmark lawsuit against 3M and 5 other companies whose use of hazardous firefighting foams caused widespread environmental contamination in New York - including rendering drinking water unsafe for tens of thousands of New Yorkers," she wrote on Twitter. Loading "Our suit would require 3M and the other companies to fully repay New York for the clean up of contamination released by these products at military and civilian airports, and the toxic mess it created in Newburgh and New Windsor, Southampton, Plattsburgh, and Rome.

"The firefighting foams made by these companies resulted in PFOA and PFOS contamination. These chemicals are extremely mobile and persistent in the environment, and they are associated with a host of serious illnesses, including cancer, liver damage, and immune system effects. "The @EPA’s current public health advisory for drinking water recommends that concentrations of PFOA and PFOS not exceed 70 parts per trillion. Scientists from the DEC found concentrations as high as 1,045,000 parts per trillion. "What happened here was unacceptable and incredibly dangerous. We are going to hold these companies accountable for endangering our health." The Environmental Protection Agency has launched national hearings on the contaminant. Environmental groups say the report should lead water agencies to boost water filtering.
