2022 EPA PFAS Health Advisory Information

On June 15, 2022, EPA announced revised health advisories for PFOA, PFOS, Gen X, and PFBS. These replace the health advisories for PFOA and PFOS of 70 ppt issued by USEPA in 2016. These new health advisories are much stricter and illustrate health impacts from PFAS at lower levels of exposure than was previously understood. Additional information is available from EPA via factsheets, a Question & Answer page, and technical information is linked to below.


Contaminant 2016 EPA Health Advisories (ng/l) 2018 and 2020 NJDEP MCLs (ng/l) 2022 EPA Health Advisories (ng/l)
PFOA 70 * 14 0.004**
PFOS 70 * 13 0.02**
PFBS N/A N/A 2000
Gen X N/A N/A 10
  *Combined for both contaminants
  ** The PFOA and PFOS Health Advisories are interim, and EPA has indicated that these values are expected to change.

Although they are non-regulatory and non-enforceable, health advisories provide technical information that federal, state, and local agencies can use to inform actions to address PFAS in drinking water.

It is important to note that New Jersey water systems must continue to comply with New Jersey’s Safe Drinking Water Act regulations and maximum contaminant levels set forth in N.J.A.C. 7:10.

NJDEP is in the process of reaching out to water systems, local governments, and the public to ensure that they are informed, and are aware of the implications of these health advisories.
