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 contamination. [...] This In Focus outlines the agency's PFAS-related actions using SDWA authorities, with particular focus on the process for evaluating contaminants for regulation under SDWA."
