Summary

In June 2018, U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, MO. Two survey profiles were collected, each including dipole-dipole and Wenner-Schlumberger configurations. For each survey a total of 28 electrodes spaced 1.0 meter (m) apart were used. During the ERT measurement, current is injected through two current electrodes and voltage is measured sequentially across multiple pairs of potential electrodes; the known current and the measured voltages are used to determine the apparent resistivity of the subsurface. Inverse modeling of [...]

Purpose

These geophysical data were collected to help characterize either the unconsolidated sediments, regolith, or combination of both above the bedrock and to determine the depth to the bedrock. These data can be used to help evaluate the overall suitability of the site for use as a waste-soil and sediment repository.
