This bill directs the Environmental Protection Agency to establish federal water pollution standards for PFAS, a group of harmful "forever chemicals" widely used in manufacturing and consumer products. The EPA must set drinking water quality criteria within three years and create pollution discharge limits for seven specific industrial categories between 2025 and 2027, including chemical manufacturers, electroplating facilities, textile mills, and landfills. The bill also requires immediate monitoring of PFAS discharges from these industries and three additional sectors like airports, with a decision by December 2025 on whether to regulate those additional sources. The legislation provides $200 million annually from 2024 through 2028 to help municipal water treatment plants manage PFAS contamination and $12 million annually for EPA implementation, ensuring funding remains available until spent.
