NY attorney general sues chemical companies for PFAS pollution

New York Attorney General Letitia James has filed a lawsuit against major chemical manufacturers, including 3M, DuPont De Nemours, Chemours, and Corteva, over allegations of widespread PFAS pollution. The legal action claims these companies knowingly distributed toxic "forever chemicals" for decades while concealing health risks such as cancer and birth defects from the public. This case underscores the increasing legal and financial liabilities facing the chemical industry as states seek to recover costs for environmental remediation and public health damages.

New York Attorney General Letitia James initiated a lawsuit on July 9, 2026, against several prominent chemical manufacturers, including 3M, DuPont De Nemours, Chemours, and Corteva. The suit alleges that these companies knowingly polluted the state's environment with per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," which are linked to severe health issues like cancer and birth defects. The state is seeking a court order to mandate warning labels on all products containing PFAS and to hold the defendants liable for the extensive environmental and public health costs associated with exposure.

The complaint asserts that the companies were aware of the toxic nature of their products for roughly 50 years but chose to deceive the public rather than disclose the risks. Specifically, the attorney general’s office claims that 3M scientists found PFAS in employee blood samples as early as the 1970s, and that DuPont monitored 50 female employees exposed to the chemicals in 1981 without informing them of the risks, even after two of the seven pregnant workers monitored gave birth to children with defects. Despite this internal data, the manufacturers continued to produce and sell PFAS-laden products for use in consumer goods like nonstick cookware, clothing, and food packaging.

The financial and operational implications for the chemical sector are significant, as a successful outcome for the state would require the defendants to fund statewide cleanup efforts, pay restitution, and face substantial financial penalties. While 3M previously announced a plan in December 2022 to phase out PFAS manufacturing by the end of 2025, this litigation focuses on the legacy of pollution caused by products such as Scotchgard and firefighting foams. The lawsuit highlights a growing trend of state-level litigation aimed at forcing the chemical industry to internalize the costs of environmental remediation and transition away from hazardous chemical formulations.
