Identifying and Managing Aqueous Film-Forming Foam (AFFF)-Derived PFAS in the Environment.

Use of aqueous film-forming foam (AFFF) has resulted in widespread occurrence of per- and polyfluoroalkyl substances (PFAS) in groundwater, drinking water, soils, sediments and receiving waters throughout the United States and other countries. This article presents research and development efforts to date by the Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP) to measure PFAS in the environment, characterize AFFF-associated sources of PFAS, understand PFAS fate and behavior in the environment, assess the risk to ecological receptors, develop in situ and ex situ treatment technologies for groundwater, treat soils and investigation derived wastes, and examine the ecotoxicity of PFAS-free fire suppression formulations.
