Surface Geophysical Data Collected at, and Adjacent to Hanscom Air Force Base, Bedford, Massachusetts, 2024

In 2024 the U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineer Center (AFCEC), conducted geophysical surveys at Hanscom Air Force Base, Hanscom Field, and surrounding areas in Massachusetts. Methods used included frequency-domain electromagnetic induction (EMI), ground-penetrating radar (GPR), horizontal-to-vertical spectral ratio (HVSR) passive seismic, electrical resistivity tomography (ERT), and transient electromagnetic induction (TEM). These data can be used to help identity aquifer boundaries, and properties. Data collection locations were determined by considering hydrologic information from previously published investigations. Specific information on the geophysical methods used and details about each instrument are provided in the Supplemental Information section of this data release.
