The StopPFAS project is aimed at developing in situ methods to efficiently sorb and immobilize PFASs in plumes in groundwater originating from hot spot areas. Different sorbents were tested for their ability to adsorb PFASs under various conditions relevant to field sites. Preliminary results indicate that activated carbon sorbents are promising candidates for in situ adsorption of PFASs in groundwater. The site investigations indicate that local hydrological and geological conditions (e.g., soil characteristics) are important for the application of sorbents in the field and pose challenges for efficient implementation of sorbent-based, in situ PFAS remediation.
