This page is for public water systems required to comply with the drinking water Per- and Polyfluoroalkyl Substances (PFAS) Rule. We will continue to add forms and guidance below to assist water systems with complying with the PFAS Rule requirements.
Please visit our Chemicals from firefighting foam and other sources page for additional consumer information on PFAS in the environment and how you can reduce your exposure.
On April 26, 2024, the Environmental Protection Agency (EPA) finalized the PFAS National Primary Drinking Water Regulation to reduce PFAS exposure in drinking water. The rule sets levels for six (6) PFAS chemicals in drinking water to protect people's health. The rule applies to community and non-transient, non-community water systems.
