Hydrogeological Evaluation of the Edwards Air Force Base Air Force Research Laboratory Area, Antelope Valley, California
In cooperation with Air Force Civil Engineer Center (AFCEC), the U.S. Geological Survey (USGS) is evaluating the hydrogeology of the Air Force Research Laboratory (AFRL) and Site 25 areas of Edwards Air Force Base (EAFB) and the adjacent North-Muroc groundwater subbasin to help determine regional groundwater movement and the possible long-term movement and pathways of contaminated water from the...Evaluation of Groundwater Resources in the Adelaida Area of San Luis Obispo County, California
Stakeholders in San Luis Obispo County are concerned that the increased demand for water use has, and will continue to, affect groundwater levels and availability in the Adelaida area. To address stakeholder concerns, the County of San Luis Obispo Board of Supervisors has asked the USGS to conduct a comprehensive evaluation of groundwater resources of the Adelaida area. - Data
Electrical resistivity tomography in the Air Force Research Laboratory Northeast AFRL and Arroyos Groundwater Areas, Edwards Air Force Base, California 2022
The U.S. Geological Survey (USGS) and Air Force Civil Engineering Center (AFCEC) have entered into a cooperative agreement to refine the hydrogeology in the Northeast AFRL and Arroyos groundwater areas of the Air Force Research Laboratory of Edwards Air Force Base. As part of these efforts, two electrical resistivity tomography (ERT) surveys- AFRL9 and AFRL10- were collected in the vicinity of theHydrogeologic Framework data and models for the Eel River groundwater basin, Humboldt County, California
This data release contains a geospatial database related to a digital 3D hydrogeologic framework model (3D HFM) of the Eel River Valley groundwater basin, California. The geospatial database contains two main data elements: (1) input data to the 3D HFM; (2) interpolated elevations and thicknesses of hydrogeologic units as a cellular array, which are a spatial representation of the 3D HFM results.Hydrogeologic data of the Russian River Watershed, Sonoma and Mendocino Counties, California (ver. 1.1, July 2023)
This data release contains digital data generated by the U.S. Geological Survey under cooperative agreements with Sonoma County Water Agency and the California State Water Resources Control Board to characterize the three-dimensional hydrogeology and water quality of the Russian River Watershed, located in the northern part of the California Coast Ranges section of the Pacific Border province. ThiRegional water table Contours of the Antelope Valley and Fremont Valley groundwater basins, Southwestern Mojave Desert, California, March 2014
Water levels were measured during March 2014 in wells in the Antelope Valley and Fremont Valley groundwater basins, southwestern Mojave Desert, California, in cooperation with the Antelope Valley-East Kern Water District, Palmdale Water District, and Littlerock Creek Irrigation District. These data document recent conditions and, when compared with previous data, changes in groundwater levels.

Edwards Air Force Base (EAFB) is located about eight kilometers (km) northeast of the city of Lancaster, California. In 1990 EAFB was placed on the U.S. Environmental Protection Agency's National priorities list due to the presence of contaminated soil and groundwater. The base was divided into Operable Units (OU) based on location and similar contaminant types (Lahontan Staff Report, 2010).

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,Surface geophysics investigations at Edwards Air Force Research Laboratory, Antelope Valley, California, 2018
The Air Force Research Laboratory (AFRL) is about 7 kilometers southwest of Boron, California, and covers 320 square kilometers of Edwards Air Force Base. The AFRL consists of 12 facilities for testing full-size rocket engines, engine components, and liquid and solid propellants.

Multiple-well monitoring site within the Poso Creek Oil Field, Kern County, California
IntroductionThe Poso Creek Oil Field is one of the many fields selected for regional groundwater mapping and monitoring by the California State Water Resources Control Board as part of the Oil and Gas Regional Monitoring Program (RMP; California State Water Resources Control Board, 2015, 2022b; U.S. Geological Survey, 2022a).

FentonDevelopment of a groundwater-simulation model in the Los Angeles Coastal Plain, Los Angeles County, California
Executive SummaryThe Los Angeles Coastal Plain (LACP) covers about 580 square miles and is the largest coastal plain of semiarid southern California. The LACP is heavily developed with mostly residential, commercial, and industrial land uses that rely heavily on groundwater for water supply. In 2010, the LACP was home to about 14 percent of California’s population, or about 5.4 million residents.Multiple-well monitoring site adjacent to the North and South Belridge Oil Fields, Kern County, California
The U.S. Geological Survey (USGS), in cooperation with the California State Water Resources Control Board, is evaluating several questions about oil and gas development and groundwater resources in California, including (1) the location of groundwater resources; (2) the proximity of oil and gas operations to groundwater and the geologic materials between them; (3) evidence (or no evidence) of fluiAuthorsRhett R.
