Summary

In June 2018, U.S. Geological Survey 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. Shear-wave (Vs) refraction surveys were collected to measure the shear-wave velocity of the subsurface, which can be used for estimating the depth to rock with the horizontal-to-vertical spectral ratio (HVSR) passive seismic reconnaissance method. A secondary objective was to determine the depth of interfaces for comparison to the resistivity surveys and frequency domain electromagnetic profiles.

Purpose

These geophysical data were collected to help characterize either the unconsolidated sediments, regolith, or a 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.
