An act relating to drinking water standards for perfluoroalkyl and polyfluoroalkyl substances

This bill establishes strict drinking water standards for harmful PFAS chemicals in Vermont. It requires the state to set a maximum contaminant level (MCL) of zero parts per trillion for six specific PFAS chemicals (including PFOA and PFOS), and a limit of 20 parts per trillion for all other testable PFAS combined. These standards apply to all public water systems in Vermont, mandating compliance by July 1, 2026. The rulemaking must be completed by the Secretary of Natural Resources by that date to protect drinking water sources.
