PFOA, PFOS and Other PFASs

EPA Actions to Address PFAS

EPA is committed to supporting states, tribes and local communities in addressing challenges with PFAS. As a part of this effort, EPA is taking action to identify solutions to address PFAS in the environment.

Toxicity Assessment for PFBS

  • On January 15, 2021, EPA released a toxicity assessment for perfluorobutane sulfonic acid (PFBS). This PFBS assessment is part of EPA’s efforts to increase the amount of research and information that is publicly available on chemicals in the PFAS family. This assessment is not a regulation, rather it provides a critical part of the scientific foundation for human health risk assessment decision-making.

Advance Notice of Proposed Rulemaking Addressing PFOA and PFOS in the Environment

  • On January 14, 2021, EPA issued an Advance Notice of Proposed Rulemaking (ANPRM) to get public comment and data to inform the agency’s ongoing evaluation of PFOA and PFOS. This information will also help the agency consider whether additional regulatory steps to address PFAS contamination in the environment are necessary.
  • Learn more about EPA’s Advance Notice of Proposed Rulemaking.
  • EPA will accept comments on the ANPRM for 60 days following publication in the Federal Register.
