Pilot-scale trials show: PFAS can be stopped before reaching groundwater
The spread of PFAS from contaminated soil to groundwater can be reduced by more than 99 per cent. This is shown by pilot-scale trials conducted by the Swedish Geotechnical Institute (SGI) in heavily PFAS-contaminated soil and groundwater at fire training areas near airports. In one of the tri-als, PFAS-contaminated water passed through an activated carbon barrier. PFAS levels were reduced by 99.99 per cent, to levels comparable with the current limit value for PFAS in drinking water.
