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.

EPA Council on PFAS

  • On April 27, 2021, Administrator Regan called for the creation of a new “EPA Council on PFAS” that is charged with building on the agency’s ongoing work to better understand and ultimately reduce the potential risks caused by these chemicals.
  • EPA’s actions to address these chemicals will be underpinned by science and will support the agency’s efforts to develop effective regulation and provide improved public health protections for all Americans.

Toxicity Assessment for PFBS

  • EPA career scientists reviewed the Toxicity Assessment for PFBS, posted on January 19, 2021, and made the determination that the conclusions in the assessment were compromised by political interference as well as infringement of authorship and the scientific independence of the authors’ conclusions. This constitutes a violation of the agency’s Scientific Integrity Policy and the documents were removed from the EPA website while the agency completed its review.
  • On April 8, 2021, after all appropriate Agency reviews and clearance as well as input from external peer reviewers, EPA announced the release of the final report, Human Health Toxicity Values for Perfluorobutane Sulfonic Acid (PFBS) and Related Compound Potassium Perfluorobutane Sulfonate. Perfluorobutane sulfonic acid (PFBS) is a member of a larger group of per- and polyfluoroalkyl substances (PFAS). The toxicity assessment is a written summary of the potential health effects associated with PFBS and identifies the dose levels at which those health effects may occur in order to calculate toxicity values.
