The U.S. Environmental Protection Agency (EPA) has issued Interim Recommendations for Addressing Groundwater Contaminated with Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) under federal cleanup programs, a priority action under EPA’s PFAS Action Plan. Aggressively addressing per- and polyfluoroalkyl substances (PFAS) is an active and ongoing effort for the agency.

“Today, we are delivering on one of our most important commitments under the PFAS Action Plan,” said EPA Administrator Andrew Wheeler in a statement. “The interim recommendations will provide clear and consistent guidance for federal cleanup programs and will help protect drinking water resources in communities across the country. This is a critical tool for our state, tribal and local partners to use to protect public health and address these chemicals.”

Federal agencies and states have asked EPA to provide guidance on this issue, and EPA is following through on its commitment. After reviewing public comments on the agency’s April 2019 draft guidance, EPA is finalizing these interim recommendations based on the available data and scientific information on PFAS toxicity. EPA acknowledges that the scientific information on these compounds continues to evolve. As part of the PFAS Action Plan, EPA is continuing to develop and assess toxicity information, test methods, laboratory methods, analytical methods, exposure models and treatment methods, among other research efforts to improve knowledge about this class of chemicals. As new information becomes available on other PFAS chemicals, the agency will consider additional recommendations as the agency advances its knowledge of these other substances. 

Today’s Action

With these interim recommendations, EPA is prioritizing public health impacts by focusing on addressing groundwater that is a current or potential source of drinking water. The guidance recommends:
