From the Document: "Detections of per-and polyfluoroalkyl substances (PFAS) in drinking water supplies and uncertainty about potential health effects associated with exposure to PFAS have increased congressional attention to the U.S. Environmental Protection Agency's (EPA) efforts to address these substances in public water supplies. Over the past decade, EPA has been evaluating several PFAS under the Safe Drinking Water Act (SDWA) to determine whether national drinking water regulations may be warranted. EPA has not issued SDWA regulations for any PFAS but has taken various actions to address PFAS in drinking water. In the 116th Congress, bills have been introduced to direct EPA to issue drinking water regulations and standards, increase monitoring and research, and take other actions to address these substances. In February 2019, EPA issued a PFAS Action Plan (EPA 823R18004), which discusses EPA's efforts to address PFAS under multiple environmental laws. This In Focus outlines the agency's PFAS-related activities using SDWA authorities, with particular focus on the process for evaluating contaminants for regulation under SDWA."
