Managing per- and polyfluoroalkyl substances (PFAS) in water resources requires a basin-scale approach. Predicted environmental concentrations (PEC) and stream-vulnerability scores for PFAS were determined for the Potomac River watershed in the eastern United States. Approximately 15% of stream reaches contained municipal and/or industrial wastewater treatment plant (WWTP) discharges...

Applying Multiple Tools to Inform Management of Per- and Polyfluoroalkyl Substances (PFAS) in the Potomac River Watershed

The reuse of municipal wastewater provides multiple benefits, including maintaining stream flow, recharging aquifers, and providing public water supply. However, along with the benefits are concerns related to the presence of ‘forever’ chemicals, like per- and polyfluoroalkyl substances (PFAS) in wastewater discharge. Managing PFAS in waterways is challenging because there are many potential PFAS...
