EPA Issues List of Contaminants for Regulatory Consideration in Drinking Water, Increasing PFAS for Review

The U.S. Environmental Protection Agency recently published its Final Fifth Drinking Water Contaminant Candidate List (CCL 5), which will serve as the basis for the agency’s regulatory considerations over the next five-year cycle under the Safe Drinking Water Act. This update includes a substantial expansion of per- and polyfluoroalkyl substances (PFAS), a first step towards identifying additional PFAS that may require regulation under the Safe Drinking Water Act. “Following public engagement and robust scientific review, the final contaminant candidate list is the latest milestone in our regulatory efforts to ensure safe, clean drinking water for all communities,” says EPA Assistant Administrator
