On June 29, 2026, the U.S. Environmental Protection Agency (EPA) issued the Draft Guidance Memorandum titled "Draft Guidance for Reducing Risk from Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS) in Biosolids" (Draft Guidance) with the corresponding Federal Register notice published on July 6, 2026. The Draft Guidance is framed as providing non-binding, voluntary recommendations to operators of wastewater treatment plants (WWTPs), landowners, farmers, state and Tribal water agencies, and the public on ways to mitigate risks from PFOA and PFOS in biosolids applied to land. The guidance does not have the force and effect of law and does not supersede existing federal, state, Tribal, or local requirements.
