Pilot scale removal of per- and polyfluoroalkyl substances and precursors from AFFF-impacted groundwater by granular activated carbon

Key Points

The aim is to evaluate the effectiveness of granular activated carbon in removing PFAS from contaminated groundwater influenced by AFFF.
Pilot scale trial using granular activated carbon for treatment of AFFF-impacted groundwater.
Water samples were collected and analyzed for PFAS concentrations before and after treatment.
Evaluation of removal efficiency based on PFAS detection levels.
Demonstrated a significant reduction in PFAS concentrations post-treatment with granular activated carbon.
Achieved over 90% removal efficiency for targeted PFAS compounds.
Results indicate the treatment method's potential for broader applications in contaminated groundwater management.

Abstract
