Abstract

The study investigated the contribution of five potential point source categories on the occurrence of 19 highly hazardous perfluoroalkyl substances (PFASs) in freshwater from the Turin metropolitan area (Italy) and assessed the quality of groundwater and surface water in compliance with European and Italian guidelines. PFASs were revealed in 29 and 24 % of the investigated shallow (unconfined aquifers) and deep (semi- and confined aquifers) wells with a total concentration, as a sum (?PFASs), of 0.01-0.71 and 0.01-0.16 ?g/L, respectively. The PFAS occurrence in shallow groundwaters appeared more related to (potentially-) contaminated and reclaimed areas, landfills and waste management plants rather than plants subjected to integrated environmental authorisations and wastewater treatment plants. Overall, PFAS occurrences increased with the degree of industrialisation and urbanisation in both unconfined and (semi-) confined aquifers. PFASs were found in 96 % of the sampling sites in streams with ?PFASs values of 0.0002-0.47 ?g/L, whilst they do not occur in the investigated lake. A slight correlation was found between wastewater treatment plants and the occurrence of PFASs in streams. The annual ?PFASs loads downstream of the Turin metropolitan Area were estimated around 150-220 kg. Exceedances of the environmental and drinking water quality standards of Italy and Europe were frequently revealed.
