Drinking water guidelines vary state-to-state

There are no federal U.S. drinking water standards for any PFAS chemicals. In June 2022, the U.S. Environmental Protection Agency (EPA) issued updated drinking water health advisories for PFOA and PFOS. These advisories are not enforceable. In March 2023, EPA published its proposed drinking water standards for six PFAS compounds, including PFOA and PFOS. EPA expects to finalize enforceable standards in the fall of 2023.

Some states have proposed or adopted their own guidelines or enforceable standards. Some of these are based on the levels of individual PFAS chemicals, while others are based on the sum of multiple PFAS chemicals.

The PFAS Exchange will be updated with new information on drinking water standards in the U.S. as they become available.

This table summarizes these standards and guidelines:

Adapted from Post 2020.

* In March 2023, EPA proposed drinking water standards for six PFAS. These proposed drinking standards would replace EPA's non-enforceable guidelines for PFOA (0.004 ng/L) and PFOS (0.02 ng/L). For PFNA, PFHxS, PFBS, and GenX, EPA proposed a hazard index (HI) of 1. This is calculated by dividing the level of each of these 4 PFAS by the corresponding value in the table above, and then calculating the sum of these 4 quotients. This approach accounts for the combined effects of exposures to multiple PFAS. A HI above 1 means the exposure may be harmful.
