PFAS in the Drinking Water Source: Analysis of the Contamination Levels, Origin and Emission Rates

Groundwater contamination caused by the use of aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS) was investigated in southern Sweden. ?PFAS concentrations groundwater ranged between 20 20,000 ng L?1; PFAS composition primarily represented PFOS PFHxS. The chain length suggested to have an impact on contaminant distribution transport groundwater. profiling showed that PFSAs- PFCAs/FTSAs-based PFAS-AFFF can be a contributor drinking water source (groundwater). emission connected during fire-training fire-fighting equipment tests at studied location. per individual fire training (semi-quantitatively) estimated as [1.4 < 11.5 ± 5.7 43.7 kg] (n = 20,000). annual estimates varied [11 401 233 1125 kg yr?1] 1005) considering possible [2 35 96] sessions year.
