Blog: U.S. EPA pushing ahead to designate PFOA and PFOS as superfund hazardous substances
Late last week, the U.S. Environmental Protection Agency (U.S. EPA) moved forward to list perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) (including their salts and structural isomers) as “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) (otherwise known as “Superfund”). EPA released a pre-publication version of a proposed rulemaking that officially begins U.S. EPA’s efforts to regulate and address per- and poly-fluoroalkyl substances (PFAS) contamination.
