From October 2016 to July 2018, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and Maine Department of Transportation, collected surface, marine and borehole geophysical surveys to characterize the subsurface materials on land and under the water at a former mine facility in Brooksville, Maine. Three water-based geophysical methods were used to evaluate the geometry and composition of subsurface materials. Continuous seismic profiling (CSP) methods provide the depth to water bottom, and, when sufficient signal penetration can be achieved, delineate the depth to bedrock and subbottom materials. Continuous resistivity profiling (CRP) and frequency domain electromagnetics (FDEM) methods...
This data release is comprised of data compiled during the construction of monitoring wells at four sentinel well sites: Trumbull, Cesar Chavez, Southern, and VA. These wells are located in southeastern Albuquerque, New Mexico (Figures 1 and 2). Between March 2013 and April 2016, the United States Geological Survey (USGS), in cooperation with the Albuquerque Bernalillo County Water Utility Authority and the U.S. Air Force Civil Engineer Center, installed 22 wells at four sites on and near Kirtland Air Force Base (KAFB). The wells, installed in response to an aviation fuel spill that was discovered in 1999 at the Bulk Fuels Facility (BFF) on KAFB, were screened at varying depths in order to characterize the aquifer...

This data release consists of historical borehole geophysical data collected by various entities and digitized by the U.S. Geological Survey to characterize the physical properties of the subsurface in and near the Mississippi Alluvial Plain from Louisiana to Missouri. The geophysical log data were collected by different Federal, state, and local agencies throughout the area and were obtained from three sources: Hart and Clark (2008), the Mississippi Department of Environmental Quality (MDEQ) (Mississippi Department of Environmental Quality, 2019), and the Louisiana Department of Natural Resources (LADNR). The log data generally consisted of either scanned .jpg or .tif images of the original log. The data were digitized...
The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 miles north-northeast of Barstow, California, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle Basins) within the NTC boundaries. In these basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, managed aquifer recharge using treated wastewater has offset water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (for example, wastewater disposal practices, landscape irrigation, and (or) leaking pipes). As part of a research study in cooperation with...
An extensive archive, estimated to contain more than 3,500 historical (1925–2020) geophysical logs collected in conjunction with past studies conducted by various entities, and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) located in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 6,058 of these records in Portable Document Format (PDF) along with a public Microsoft Access database and comma-separated values (CSV) text file containing detailed well header information for each record.
