The group of chemicals known as PFAS (per- and poly-fluoroalkyl substances) are high on the federal regulatory agenda for 2022, as implementation of EPA’s “PFAS Strategic Roadmap” proceeds. One potential consequence will be new additions to California’s “Prop 65 List” of chemicals known to cause cancer or reproductive harm. Already, two PFAS substances are subject to Prop 65 warning and labeling requirements (PFOA and PFOS), with a third (PFNA) subject to enforcement starting in 2023. New federal Health Advisory Levels (HALs) announced on June 15, 2022 may provide the basis to add another two PFAS to the list (PFBS and GenX).
