Summary

Pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA” or “Superfund”), the Environmental Protection Agency (EPA) is designating two per- and polyfluoroalkyl substances (PFAS)—perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers—as hazardous substances. 

The Agency reached this decision after evaluating the available scientific and technical information about PFOA and PFOS and determining that they may present a substantial danger to the public health or welfare or the environment when released. The Agency also determined that designation is warranted based on a totality of the circumstances analysis, including an analysis of the advantages and disadvantages of designation.
