[Corporate Strategy] DuPont, Chemours and Corteva Reach $455 Million Settlement of PFAS Claims with North Carolina — Paid Over 15 Years, Subject to Dismissal of the Litigation
The settlement clearly shows that PFAS regulation is shifting from restrictions on current and future manufacturing and use to large financial burdens and cost-sharing for past environmental impacts. As the three companies' MOU-based allocation of liability illustrates, in the chemical industry the allocation of environmental liabilities persists over long periods, even among companies that have gone through past restructurings and spin-offs. In corporate valuation, risk management that assesses not only the regulatory compliance of current products but also past emission history and potential litigation and settlement risk as a whole has become essential.

U.S. EPA PFAS National Primary Drinking Water Regulation (NPDWR)
The National Primary Drinking Water Regulation (NPDWR) finalized by the U.S. Environmental Protection Agency (EPA) in April 2024 under the Safe Drinking Water Act (SDWA) set nationwide, legally enforceable Maximum Contaminant Levels (MCLs) for specific PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, HFPO-DA (GenX), and certain mixtures. The MCLs for PFOA and PFOS are 4.0 parts per trillion (ppt) each. In May 2026, however, EPA proposed a rule that would keep the PFOA and PFOS MCLs while allowing water systems that apply to extend their compliance deadline from 2029 to 2031, and a separate rule that would rescind the regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures. Public comment on both proposals closed on July 20, 2026. As of September 27, 2026, neither has been finalized, and the current rule remains legally in effect.
