New York Sues 3M and DuPont for PFAS Contamination and Alleged Fraud
New York’s lawsuit against 3M and DuPont for PFAS contamination and alleged fraud extends prior state settlements and underscores nationwide exposure documented in NHANES. The case targets both historical pollution and withheld toxicity data, setting precedents for treatment funding and regulatory gaps.
The complaint alleges the companies knew PFAS caused liver toxicity, immune suppression, and developmental effects yet continued sales and failed to disclose internal studies dating to the 1960s. It seeks damages for statewide drinking-water treatment costs and natural-resource restoration after detections above the EPA’s 4 ng/L MCL in multiple Long Island and Hudson Valley aquifers.
New York’s action fits a pattern seen in Minnesota’s 2018 $850 million 3M settlement and the 2023 Chemours-DuPont multistate agreement. NHANES serum data show median PFOA levels fell only 20 % after the 2015 PFOA Stewardship Program phase-out, indicating legacy contamination and ongoing short-chain replacement exposure.
The suit also highlights gaps in federal regulation: while EPA’s 2024 MCLs address six PFAS, states still lack enforceable standards for the >12,000 other compounds now detected in consumer products. Plaintiffs cite internal DuPont memos showing early recognition of groundwater mobility yet continued use in firefighting foams and packaging.
Next steps include discovery of company testing records and possible coordination with the EPA’s ongoing TSCA risk evaluations; outcomes will likely shape allocation of the $10 billion+ in anticipated national remediation costs.
EPA: Median U.S. serum PFOA levels will drop below 1 ng/mL in NHANES 2031-32 cycle if state settlements drive full MCL compliance by 2029.
