Legal action is being taken over alleged contamination of municipal water supplies in US cities with perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) – collectively known as per- and polyfluoroalkyl substances (PFAS).
PFAS contamination is typically localised and associated with industrial facilities where PFAS were produced or used to manufacture other products. Such contamination has also been found on or near military airfields, where aqueous film forming foam (AFFF), which contains PFOA and PFOS, was used by firefighters.
The latest lawsuit was filed in early August by the City of Newburgh in New York State. It is suing the US federal government, New York State, and associated agencies, and manufacturers for alleged contamination of its primary water supply, which has been closed for more than two years.
