Shenandoah River Accumulated Wastewater Ratio (Version 2.0)
Incedental wastewater reuse from streams that receive discharges from Wastewater Treatment Facilities (WWTF) has the potential to be a significant contributor of Endocrine Disrupting Chemicals. An ArcGIS model of WWTFs, NHDPlus Version 2 stream networks (USGS and EPA 2012), and gage stations across the Shenandoah River watershed was created to calculate accumulated wastewater in percent of streamflow (ACCWW%) and Predicted Environmental Concentrations (PECs) of select constituents. Virginia and West Virginia Pollutant Discharge Elimination System (VPDES, WVPDES) discharge facilities, outfall locations, and stream gages were spatially joined to the nearest river segment. Wastewater inputs from outfall locations were summarized by river segment COMIDs (Common identifier). All wastewater discharge facility locations were verified with United States Environmental Protection Agency (EPA) Facility Registry Service. WWTFs were categorized as industrial or municipal based on the type of permit they were granted. Accumulated wastewater, ACCWW% and PECs were calculated using a python script. Maximum facility-capacity permitted wastewater discharge and 2015 average-annual wastewater discharge were used to calculate ACCWW% for mean-annual and mean-August streamflow conditions. PECs were only calculated for mean-annual streamflow and 2015 average-annual municipal discharges.
