The Environmental Protection Agency (EPA) recently announced the winners of the Innovative Ways to Destroy PFAS Challenge, which SERDP and ESTCP co-sponsored. This challenge sought proposals for non-thermal technologies and approaches to destroy per- and polyfluoroalkyl substances (PFAS) in concentrated aqueous film forming foam (AFFF) without producing any harmful byproducts.
Challenge winners’ approaches will strengthen and advance efforts to remove PFAS from unused AFFF. Their proposals were required to destroy at least 99 percent of the PFAS in unused AFFF concentrates, including PFAS byproducts that may form by volatilization, particulates, and leaching from effluents. To learn more about the challenge and the winners’ proposals, visit the EPA’s Innovative Ways to Destroy PFAS Challenge webpage.
Over the past decade, SERDP and ESTCP have funded research and demonstration efforts aimed at improving understanding of occurrence, fate and transport, remedial treatment options, and ecotoxicity at AFFF-impacted sites. Projects are also advancing the development of next generation PFAS-free foams.
