Hamburg, Rubin, Mullin, Maxwell & Lupin announced that Steven A. Hann was the sole speaker at a Pennsylvania Municipal Authorities Association webinar titled “EPA’s New Drinking Water Regulation for PFAS.”

During this webinar, Hann focused on PFAS-related regulations issued by EPA in April 2024. He discussed EPA’s regulation setting enforceable limits for certain PFAS in drinking water, including application of a hazard index for the regulation of mixtures of PFAS compounds, new initial monitoring requirements, and how to determine compliance with the regulation’s ongoing monitoring requirements. In addition, he discussed another new EPA regulation designating certain PFAS as hazardous substances under CERCLA, and the impact of such regulation on, among others, public water systems and wastewater treatment plants.
