Contaminants of Emerging Concern (CECs), chemicals that may be harmful to human health or the environment but that are not yet regulated, are capturing the public's attention. For example, EPA just proposed to list perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), two chemicals in the per- and polyfluoroalkyl substances (PFAS) group that are pervasive in the environment and may be harmful to human health, as Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) hazardous substances. EPA will be accepting comments on the proposed rule until November 7, 2022, and, according to the PFAS Strategic Roadmap, a final rule is expected in Summer 2023.
