Vector geospatial data of interpolated groundwater level altitude associated with a groundwater-level map of Fauquier County, Virginia, October - November 2018

This dataset is the product of a geospatial interpolation using groundwater-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 129 groundwater wells in Fauquier County, VA from October 29 through November 2, 2018 and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of groundwater levels in 50-foot intervals. Methodology is detailed in USGS SIR 2022-5014 "Groundwater-level contour map of Fauquier County, VA, October - November 2018." Attributes include groundwater-level altitude in both decimal feet and meters. Horizontal coordinates are referenced to the geographic coordinate system North American Datum of 1983 (NAD 1983) and groundwater-level altitudes are referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29). The projected coordinate system is Albers Conic Equal Area with a central meridian of -96.0, standard parallels of 29.5 and 45.5, and a latitude of origin of 23.0.
