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...
West Virginia Water-Monitoring-Site Mapper
The Water-Monitoring-Sites Mapper is an interactive map of West Virginia water monitoring-site locations from the USGS National Water Information System (NWIS). It provides access to surface water, groundwater, and water quality monitoring data for active sites. The functionality includes query, select, tabular display by county, hydrologic unit code (HUC), and exporting spatial and tabular data.
Virginia Water-Monitoring-Site Mapper
The Water-Monitoring-Sites Mapper is an interactive map of Virginia water monitoring-site locations from the USGS National Water Information System (NWIS). It provides access to surface water, groundwater, and water quality monitoring data for active sites. The functionality includes query, select, tabular display by county, hydrologic unit code (HUC), and exporting spatial and tabular data.
Estimating Drought Streamflow Probabilities for Virginia Streams
Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams. 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.
GIS-based landscape analysis to identify sources of endocrine disrupting chemicals
De facto wastewater reuse from Wastewater Treatment Facilities (WWTF) has the potential to contribute unregulated Endocrine Disrupting Chemicals. To visualize the typical contributions of treated effluent into Shenandoah River watershed streams, an ArcGIS model of WWTFs, NHDPlus Version 2 (USGS and EPA 2012) stream networks, and USGS Streamgages across the Shenandoah River watershed was developed.
West Virginia Real-Time Precipitation Network
This interactive map shows current and cumulative rainfall total for precipitation sites in West Virginia. Map provides real-time precipitation radar image to overlay from National Weather Service.

Loads and trends in the Chesapeake Bay nontidal monitoring network: results through Water Year 2018
The mapper provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine the results for river basins and individual sites. Data used in the mapper, and the methods used to compute trends and loads, can be also accessed from the tool.
Kentucky Drought Condition Monitor
The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...
Fauquier County Groundwater Recharge
A Soil-Water-Balance (SWB) model (Westenbroek and others, 2010) was developed to estimate the mean annual water budget for the period 1996 through 2015 and the annual water budget for a drought-year in 2001. This application allows the display and...
Delaware River Basin Monitoring-Site Mapper
The Water-Monitoring-Site Mapper is an interactive map of the Delaware River Basin next-generation integrated water observing system with locations from the USGS National Water Information System. Piloting the NextGen water observing system in the Delaware River Basin provides an opportunity to support innovative modern water prediction and decision support systems in a complex river system....
Drought Streamflow Probabilities in Northeast Region
Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.
