Abstract:

The overall goal of this project was to attain improved insight into the fundamental fate and transport processes that control per- and polyfluoroalkyl substance (PFAS) fate and transport as well as comingled chlorinated solvents and/or fuel hydrocarbons in groundwater at aqueous film forming foam (AFFF)-impacted sites. We focused on the release and transformation of polyfluorinated substances to perfluoroalkyl acids (PFAAs) in source zones as well as the impact of commonly employed remediation technologies for co-contaminants on PFAS fate.
