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

This bill directs Vermont's Secretary of Natural Resources to update drinking water standards for specific chemicals known as PFAS. It requires setting a maximum contaminant level of zero parts per trillion for six named PFAS compounds and a combined limit of 20 parts per trillion for all other testable PFAS. The Department of Environmental Conservation must finalize these rules by July 1, 2024, affecting water treatment facilities and public water systems in the state. The legislation takes effect on July 1, 2023, giving agencies time to develop the necessary regulatory framework.
