New York Attorney General Letitia James files a lawsuit seeking to hold multiple companies liable for PFAS, often called “forever chemicals,” which persist in the environment. According to the complaint, the defendants sold PFAS for use in consumer products such as cosmetics and non-stick cookware, and the state alleges the companies knew about environmental and health risks associated with the chemicals and concealed that information from the public. Several outlets report that the case also centers on allegations that the companies engaged in wrongdoing that includes fraud and concealment, and that some firms began phasing out certain PFAS while, in the state’s view, they still hid dangers from consumers and the public. The state also frames the conduct as creating a public nuisance. The lawsuit targets major manufacturers, including 3M and DuPont, and additional companies are named across reports. The filings seek accountability for alleged contamination of drinking water and broader environmental harms, as well as costs associated with the alleged impact on public health. The companies have not been described in the reports as conceding the allegations.
