Selected borehole geophysical logs from three contaminated sites in California, Wisconsin, and New Jersey

Metadata Updated: July 6, 2024

Borehole geophysical logs were collected to characterize bedrock aquifers at three contamination sites located in California, Wisconsin, and New Jersey. The data were collected by the U.S. Geological Survey (USGS) and the University of Guelph from 2014 to 2015 as part of the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) initiatives to apply geophysical methods at fractured-rock sites contaminated with chlorinated solvents. Logs were collected in open boreholes completed in fractured rock. Each borehole was logged with natural gamma, electromagnetic induction, normal resistivity, single-point resistance, spontaneous potential, induced polarization, magnetic susceptibility, acoustic imaging, and nuclear magnetic resonance methods. In addition, total volatile organic compound (TVOC) samples were extracted from solid core and collected at discrete locations that averaged every 0.5 to 1.0 foot along depth of the borehole. The borehole geophysical data are summarized for each of the sites. These data were used in a machine learning exercise that explored the relations between borehole log measurements and contaminant distribution.
