GeoPro Talks: Best Practices for Investigating PFOS-Alternative AFF
This presentation explores the development of aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS), focusing on the rise of next-generation C6 foams introduced in the 2000s. Promoted as environmentally friendlier alternatives to PFOS-based AFFFs, these formulations primarily feature 6:2 fluorotelomer betaine (6:2 FTAB)—a PFAS compound that remains unregulated and lacks an approved analytical […]
