Federal lawmakers are once again seeking to protect drinking water and wastewater utilities from some of the costs associated with PFAS contamination. A bipartisan bill introduced by U.S. Reps. Marie Gluesenkamp Perez, D-Washington, and Celeste Maloy, R-Utah, if enacted, would shield utilities from legal costs and cleanup liabilities associated with PFAS contamination. The U.S. Environmental Protection Agency has designated two types of PFAS — PFOA and PFOS — as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act. Local utilities expressed concerns that they would need to pay to remove PFAS from drinking water, which can be an expensive endeavor.
