Electrical resistivity tomography (ERT) geophysical survey at Brookside West, Beaumont, California, December 2024

Surface electrical resistivity tomography (ERT) data were acquired December 2 - 5, 2024 by the U.S. Geological Survey (USGS) at the San Gorgonio Pass Water Agency's Brookside West site in Beaumont, California. The purpose of this survey was to map near surface geologic structure in an area that the San Gorgonio Pass Water Agency plans to develop as a managed aquifer recharge site. Three ERT profiles were acquired at depths up to 50 meters (m) using the Advanced Geosciences, Inc. SuperSting R8 resistivity meter. This data release includes the raw and processed resistivity data as well as inverted resistivity models. All data are provided as digital data, and data fields for each file type are defined in the respective data dictionary.
