Hydraulic-head datasets for the surficial and Frederica aquifers at Dover Air Force Base, Kent County, Delaware: May 2020, April 2021, and September 2021

This data release contains information on hydraulic head in the near-surface aquifers at Dover Air Force Base, a 4,000-acre military installation located in Kent County, Delaware. The hydraulic-head data, collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force Civil Engineer Center (AFCEC), are based on water-level measurements taken during three synoptic events: May 2020, April 2021, and September 2021. Hydrogeologic units represented in this dataset include the shallow surficial (SS), deep surficial (DS), and Frederica (FR) aquifers. Data are provided in comma-separated value (.csv) and georeferenced raster (.tif) file formats to facilitate mapping and analysis using a geographic information system (GIS) or other computer software. Data in the .csv file include USGS site identification number, local well identifier, well coordinates, aquifer designation, land-surface datum, well depth, synoptic group, water-level date and time, and hydraulic-head value. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
