Overview

  • The EPA announced it will maintain 4 ppt limits for PFOA and PFOS but extend the compliance deadline for these chemicals to 2031, giving utilities additional time to meet standards.
  • Limits on three other PFAS chemicals, including GenX, and a mixture of PFAS types will be rescinded and reconsidered under a new regulatory process set to begin this fall.
  • The Biden-era rule, finalized in 2024, was expected to reduce PFAS levels in drinking water for millions and address health risks such as cancer and developmental issues.
  • Environmental groups have condemned the rollback, arguing it undermines public health protections and may violate the Safe Drinking Water Act's anti-backsliding provisions.
  • The EPA plans to finalize the revised rule by spring 2026, with Administrator Lee Zeldin emphasizing the need for flexibility to support rural and small water systems.
