Summary
These interpolated groundwater levels and altitudes product, for Monroe County, WV, was derived from groundwater-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 257 groundwater wells during October 23, 2017 through September 19, 2019, and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of groundwater altitudes in 50-foot intervals. Attributes include groundwater altitudes in decimal feet. Horizontal coordinates are referenced to UTM zone 17, NAD83, and groundwater altitudes are referenced to the North American Vertical Datum of 1988 (NAVD88). The potentiometric surface map, based on the 257 groundwater measurements, was constrained by the NHD streamlines [...]
Summary
These interpolated groundwater levels and altitudes product, for Monroe County, WV, was derived from groundwater-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 257 groundwater wells during October 23, 2017 through September 19, 2019, and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of groundwater altitudes in 50-foot intervals. Attributes include groundwater altitudes in decimal feet. Horizontal coordinates are referenced to UTM zone 17, NAD83, and groundwater altitudes are referenced to the North American Vertical Datum of 1988 (NAVD88). The potentiometric surface map, based on the 257 groundwater measurements, was constrained by the NHD streamlines and location of known springs. ArcGIS Pro was used to make contour lines from point data, and the resulting contours were further edited in areas where automated methods were not as precise given fewer data points; the areas edited were where the land-surface elevation was lower than water-surface elevation, approximately.
The purpose of this dataset is to provide a geospatially referenced dataset of the potentiometric surface map figure produced in the USGS SIR 2023-5121 "Hydrogeology, Karst, and Groundwater Availability of Monroe County, West Virginia, 2017-2019." This product provides groundwater-level altitudes in Monroe County, WV, and may be useful for other applications or analysis requiring groundwater levels and altitudes.
