AFFF Firefighting Foam
OpenFASTCausation
PFAS (per- and polyfluoroalkyl substances) in AFFF firefighting foam are linked to kidney cancer, testicular cancer, thyroid disease, and liver damage. Firefighters and military personnel with occupational exposure face highest risk. EPA has set near-zero MCLs for PFOA and PFOS in drinking water. 3M internal documents show knowledge of PFAS toxicity dating to the 1970s.

The Environmental Protection Agency (EPA or the Agency) is seeking public input and data to assist in the consideration of potential development of future regulations pertaining to per- and polyfluoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). The Agency is seeking input and data regarding potential future hazardous substance designation under CERCLA of: Seven PFAS, besides perfluorooctanoic acid (PFOA) and perflu
Notice published 2023-05-12
DoD is issuing an interim rule amending the Defense Federal Acquisition Regulation Supplement (DFARS) to implement a section of the National Defense Authorization Act for Fiscal Year 2020.
The Environmental Protection Agency (EPA or the Agency) is proposing to amend its regulation under the Resource Conservation and Recovery Act (RCRA) by adding nine specific per-and polyfluoroalkyl substances (PFAS), their salts, and their structural isomers, to its list of hazardous constituents. These nine PFAS are perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorobutanesulfonic acid (PFBS), hexafluoropropylene oxide-dimer acid (HFPO-DA or GenX), perfluorononanoic aci
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 tha
