The agency is moving toward establishing a drinking water standard for PFOA and PFOS and has stated that it is considering avenues for regulating additional groups of PFAS under the Safe Drinking Water Act (SDWA) as well. The SDWA is just one of several statutes EPA is actively considering for additional regulation of PFAS. For example, EPA is considering hazardous substance and hazardous waste designations under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and/or the Resource Conservation and Recovery Act (RCRA).
