PFAS Litigation and Regulatory Pressure Intensifies Globally

- The EPA's national drinking water standard, finalized in April 2024, sets enforceable Maximum Contaminant Levels (MCLs) for PFOA and PFOS at 4.0 parts per trillion (ppt). It also establishes MCLs for PFNA, PFHxS, and GenX chemicals at 10 ppt. Public water systems must complete initial monitoring by 2027 and implement solutions to reduce PFAS if levels exceed these standards by 2029. - France's decree, taking effect January 1, 2026, bans PFAS in cosmetics, ski wax, and most textiles and footwear. It sets specific residual concentration limits, including 25 parts per billion (ppb) for individual PFAS and 250 ppb for the sum of PFAS. The ban will expand to cover all textiles, with limited exceptions, starting in 2030. - The European Union is evaluating a broader restriction on over 10,000 PFAS chemicals, with the European Chemicals Agency (ECHA) expected to complete its scientific evaluation by the end of 2026. This follows a proposal submitted by five member states, including Germany and the Netherlands, in January 2023. - U.S. states are not waiting for federal implementation and are enacting their own aggressive timelines; for example, Minnesota's reporting deadline for PFAS in products is July 1, 2026, with a full ban on intentionally added PFAS in all products, unless deemed essential, taking effect in 2032. Twenty states now have bans on PFAS in food packaging. - Litigation is expanding beyond manufacturers like 3M, which reached a $10.3 billion settlement with public water suppliers, to include downstream users in sectors such as automotive and consumer goods. As of July 2024, total settlements in the Aqueous Film-Forming Foam (AFFF) multidistrict litigation have surpassed $14 billion, including significant amounts from DuPont ($1.185 billion) and Tyco ($750 million). - The U.S. EPA's Toxic Substances Control Act (TSCA) reporting rule requires manufacturers and importers to report extensive data on PFAS use dating back to 2011. The reporting window for most entities opens in mid-2025, with no de minimis exemptions for volume, creating a significant compliance burden to trace and disclose PFAS throughout complex supply chains. - Remediation costs are a major financial risk, with one analysis estimating that cleaning up PFAS in U.S. drinking water systems could range from $120 billion to $175 billion. In Europe, the estimated annual healthcare costs alone from PFAS exposure are between €52 billion and €84 billion. - Public companies face increasing pressure for transparent disclosure of PFAS-related risks in their SEC filings. Companies are being advised to update risk factors and Management's Discussion and Analysis (MD&A) sections to reflect potential liabilities from regulations, litigation, and reputational damage, moving beyond generic environmental risk statements.
