Subsurface activated carbon barriers can reduce the spread of PFAS in groundwater
Researchers at the Swedish Geotechnical Institute have evaluated whether an activated carbon barrier can reduce the spread of PFAS at a heavily contaminated site. The results show that it can. After two years, PFAS concentrations had fallen by more than 99.9%. The technology could become an important tool for protecting drinking water and nature from persistent PFAS chemicals. The findings have been published as a peer-reviewed scientific article in the Remediation Journal.
