Select borehole data for Edwards Air Force Base and vicinity, Antelope Valley, CA

Metadata Updated: October 29, 2023

Edwards Air Force Base (EAFB) is located in Kern County, CA, approximately 35 kilometers (km) northeast of Lancaster and 9 km south of California City. The Air Force Research Laboratory (AFRL) is situated on EAFB, approximately 7 km southwest of Boron, CA. Release of contaminants from the AFRL facilities have contaminated local groundwater, which is mostly restricted to fractured granitic bedrock, but studies indicate that the groundwater and contaminant plumes have moved into alluvial deposits to the north and northwest (AECOM, 2014). The U.S. Geological Survey (USGS) and the Air Force Civil Engineer Center (AFCEC) entered into a cooperative agreement in 2017 to develop a hydrogeologic framework model to help determine groundwater movement and the geologic and lithologic structures that control groundwater movement. This dataset of lithologic descriptions from boreholes was used for lithologic analysis to build a hydrogeologic framework in the EAFB area. Data includes the California Department of Water Resources borehole log number (if known), state well number (if applicable), location information, and detailed lithologic descriptions, including depth to bedrock where present, for each borehole.
