EPA Floats Thousands Of PFAS, Other Chemicals For Possible SDWA Limits

摘要

EPA is proposing to include thousands of per- and polyfluoroalkyl substances (PFAS), as well as groups of disinfection byproducts (DBPs) and cyanotoxins, along with scores of other individual chemicals, on the latest iteration of its periodic Safe Drinking Water Act (SDWA) list of candidates for future regulations. EPA's proposed contaminant candidate list 5 (CCL5), released July 12, includes a total of 81 individual contaminants and groups of chemicals, the agency says in a Federal Register notice slated for publication in the coming days. The agency will take comment on the proposed list for 60 days after its publication. The list is comprised of 69 chemicals or chemical groups, including all PFAS except for the two the agency is already planning to regulate, a group of 23 unregulated DBPs, several cyanotoxins and a host of high-profile individual contaminants that states and others have long urged the agency to regulate, such as 1,4-dioxane, bisphenol A, methyl tert-butyl ether (MTBE), methylmercury and others.
