Distribution of Per- and Polyfluoroalkyl Substances in River Systems
The introduction of per- and polyfluoroalkyl substances (PFAS) into the environment are from numerous point and non-point sources. Typically, the investigation of PFAS impacts to surface water have focused on recognized point-sources (e.g. wastewater treatment plants), and not non-point sources such as stormwater or ambient air deposition. PFAS in surface water was characterized for rivers in New England and Indiana. More than 40 samples were collected at locations upriver and downriver of major population areas and confluences with other streams associated with known point sources. This presentation will present the changes in PFAS composition and concentration with population-loading and non-point sources on the river systems and identify plausible anthropogenic background levels of PFAS in surface water as a point of comparison to surface water quality criteria.
