38th Environmental Permitting Summer School

The EPA is required by the Safe Drinking Water Act to issue a list of unregulated contaminants once every five years to be monitored by public water systems. The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) was published on December 27, 2021, and requires public water systems nationwide to sample collection for 29 PFAS constituents and lithium between 2023 and 2025. Before sampling concluded, however, the EPA issued a National Primary Drinking Water Rule (NPDWR) regulating 6 PFAS. Additionally, EPA issued or proposed several other regulations to manage PFAS chemicals and releases. In this session, a panel of industry professionals, regulators, and attorneys will discuss perspectives, challenges, and implications of the UCMR5 results and EPA’s new PFAS regulations.
