EPA Announces PFAS Drinking Water Standards and Superfund Liability
The Environmental Protection Agency finalized the first-ever national drinking water standard for per- and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals.' The rule sets maximum contaminant levels for six PFAS compounds, including PFOA and PFOS at 4 parts per trillion — among the most stringent environmental standards ever imposed.
The EPA also designated PFOA and PFOS as hazardous substances under the Superfund law (CERCLA), enabling the agency to require polluters to pay for cleanup. This designation creates potential liability for any entity in the chain of production, use, or disposal of these chemicals.
The rules will require thousands of water systems nationwide to install treatment technology to remove PFAS contamination. The EPA estimates compliance costs at $1.5 billion annually, with $9 billion in federal funding available to assist water utilities.
Practical Impact
Water utilities must begin monitoring for PFAS and plan for treatment system installation. Manufacturers, including those in aerospace, electronics, and firefighting foam, face potential Superfund cleanup liability. Real estate transactions should include PFAS due diligence. The litigation landscape for PFAS claims continues to expand rapidly, with multidistrict litigation consolidating thousands of cases.
