On June 15, 2022, the Environmental Protection Agency (EPA) announced interim and final health advisory levels for four per- and polyfluoroalkyl substances (PFAS) found in public drinking water systems and wells across country and the state. These are the only health advisory levels established by the EPA at this time for PFAS compounds:
- Interim updated Health Advisory for PFOA = 0.004 parts per trillion (ppt) with a minimum reporting level of 4 ppt
- Interim updated Health Advisory for PFOS = 0.02 ppt with a minimum reporting level of 4 ppt
- Final Health Advisory for GenX chemicals (HFPO-DA) = 10 ppt
- Final Health Advisory for PFBS = 2,000 ppt
Health advisories are non-enforceable and non-regulatory levels that provide information on contaminants that can cause human health effects and are known or anticipated to occur in drinking water.
While unenforceable, these advisories indicate the level of drinking water contamination below which adverse health effects are not expected to occur. Health advisories provide technical information that federal, state, and local officials can use to inform the development of monitoring plans, investments in treatment solutions, and future policies to protect the public from PFAS exposure.
