Science and Products
Interpolated groundwater levels and altitudes for Monroe County, West Virginia, 2017-2019
Fluorescein and Rhodamine WT concentration and recovery data for select samples collected in Monroe County, West Virginia, in August and September 2019
Dataset of C1-C6 Dissolved Trace Hydrocarbon Measurements in the Western "Wet Gas" Part of the Marcellus Shale Oil and Gas Play in West Virginia, U.S.A. Collected Between June and August 2018
Dataset of trace dissolved hydrocarbons in surface water and groundwater in North Dakota, Pennsylvania, Virginia, and West Virginia between 2014 and 2017
Site and Groundwater-Quality Sample Data for Abandoned Underground Coal Mine Aquifers in West Virginia, July 13, 1973 through September 7, 2016
Hydrogeology, karst, and groundwater availability of Monroe County, West Virginia
Groundwater quality in abandoned underground coal mine aquifers across West Virginia
Groundwater quality and geochemistry of the western wet gas part of the Marcellus Shale Oil and Gas Play in West Virginia
Groundwater quality and geochemistry of West Virginia’s southern coal fields
Groundwater-quality data associated with abandoned underground coal mine aquifers in West Virginia, 1973-2016: Compilation of existing data from multiple sources
Use of modflow drain package for simulating inter-basin transfer in abandoned coal mines
Hydrogeology, groundwater flow, and groundwater quality of an abandoned underground coal-mine aquifer, Elkhorn Area, West Virginia
Assessment of hydrogeologic terrains, well-construction characteristics, groundwater hydraulics, and water-quality and microbial data for determination of surface-water-influenced groundwater supplies in West Virginia
Hydrologic budget and conditions of Permian, Pennsylvanian, and Mississippian aquifers in the Appalachian Plateaus physiographic province
Water quality of groundwater and stream base flow in the Marcellus Shale Gas Field of the Monongahela River Basin, West Virginia, 2011-12
Quality-assurance plan for groundwater activities, U.S. Geological Survey, Washington Water Science Center
Groundwater quality in West Virginia, 1993-2008
Interactive Map: Virginia and West Virginia Groundwater Levels and Trends
The Virginia and West Virginia Groundwater Levels and Trends web application provides access to groundwater level data from continuous groundwater wells across Virginia and West Virginia. Continuous wells include real time and non-real time wells. Data update daily and are compared to long-term monthly statistics.
Geonarrative: Land Motion and Subsidence on the Virginia Coastal Plain
Along the coast of Virginia, the USGS and our partners are constantly monitoring our land and waters in new and innovative ways. In Virginia, scientists at the Virginia and West Virginia Water Sciences Center are drilling deep into the Earth to assess the impacts of groundwater use. By studying the impacts of groundwater use, scientists can determine associated risks, such as land subsidence.
