Event Summary

On July 9, 2026, New York Attorney General Letitia James filed a lawsuit in Albany County Supreme Court against 3M, DuPont, Chemours, Corteva, and EIDP, alleging that the companies knowingly sold products containing toxic PFAS (per- and polyfluoroalkyl substances) without warning consumers of the health and environmental risks. The state seeks cleanup funding, damages, and consumer warnings. The companies have not yet responded. This is part of a broader trend of government actions against PFAS manufacturers.
