Behavior of Perfluroalkyl Chemicals in Contaminated Groundwater
Abstract
This project evaluated physicochemical and biological parameters for determining the fate and transport of PFAAs in groundwater relevant to AFFF-impacted sites in the presence of co-contaminants and during their remediation. Results indicate PFM transport can be retarded by NAPLs. PFAAs do not appear to significantly affect hydrocarbon degradation, though they do induce biofilm formation and interfere with microbial dehalogenation. ISCO can result in increased PFM sorption. Many PFAAs rapidly desorb from AFFF-impacted soils, though PFAA precursors desorb more slowly. Advective studies support the strong role of pH on PFAA sorption. Finally, ISCO may facilitate conversion of precursors to PFAAs.
