At a May 22 national summit, EPA Administrator Scott Pruitt announced his intention to initiate the process to propose to list the fluorochemicals perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) hazardous substances for the purposes of some federal environmental statutes, including the Comprehensive Environmental Response, Compensation, and Liability Act (or, Superfund). The Administrator also announced that the agency will initiate steps for evaluating whether to set a maximum contaminant level for PFOS/PFOA under the Safe Drinking Water Act. Additionally, Administrator Pruitt indicated that the agency intends to develop national groundwater cleanup recommendations for the chemicals to assist with Superfund remediation, as well as toxicity values for two other types of per- and polyfluoroalkyl substances (PFAs) — GenX and PFBS. Previously, EPA had issued a health advisory for PFOS/PFOA at 70 parts per trillion. PFOS/PFOA appear in numerous industrial and consumer products like carpet and firefighting foams.
