What you need to know about the EPA’s new drinking water standards and PFAS

The Environmental Protection Agency (EPA) announced new drinking water standards to limit the concentration of a family of forever chemicals known as Per- and Polyfluoroalkyl Substances, or PFAS. PFAS chemicals were widely used for years in various industrial and consumer products and have been linked to health issues.

The new limits are a significant move by the EPA to safeguard the public from the impacts of PFAS chemicals. The final rule sets limits for five individual PFAS chemicals and establishes a hazard index level for mixtures of two or more PFAS chemicals. The limit for PFOA and PFOS is set at four parts per trillion.

The final rule requires all public water systems monitor for PFAS and complete the initial monitoring by 2027. If PFAS levels are found to exceed the statutory limit, the water system has until 2029 to implement solutions to reduce the PFAS level. Beginning in 2029, if a water system is found to exceed the new limits, the community is required to provide a public notification of the violation.

See the Fact Sheet at epa.gov for a detailed explanation of the new standards.
