Integrated assessment of wastewater reuse, exposure risk, and fish endocrine disruption in the Shenandoah River watershed

Reuse of municipal and industrial wastewater treatment plant (WWTP) effluent is an important component in augmenting global freshwater supplies. The Shenandoah River Watershed was selected to conduct on-site exposure experiments to assess endocrine disrupting characteristics of different source waters. This investigation of the Shenandoah River Watershed integrates WWTP wastewater reuse...

GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...

Shenandoah River Accumulated Wastewater Ratio

De facto wastewater reuse from Waste Water 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 ratio. Virginia Pollutant Discharge Elimination...

Basin Characteristics Rasters for West Virginia StreamStats 2021

The U.S. Geological Survey (USGS) has calculated over 25 different basin characteristics as part of preparing the West Virginia StreamStats 2021 application. These datasets are raster representations of various environmental, geological, and land use attributes within the West Virginia StreamStats 2021 study area and will be served in the West Virginia StreamStats 2021 application to...

Interactive Map: Monitoring Virginia Eastern Shore Groundwater Conditions

Groundwater levels in layered aquifer systems like the Virginia Eastern Shore are often monitored using wells in multiple aquifers at the same location. Colors in the simplified cross-section illustration below correspond to the circles representing wells on the map. The list of monitoring-well layers can be used to control the map display of wells for individual aquifers.

Interactive Map: Estimating Drought Streamflow Probabilities for Virginia Streams

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams 5 to 11 months in advance. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

Interactive Map: GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.
