Johnson Katherine L. Pappas Neil C. Terry Dale D. Werkema Eric A. White Robert G. Ford Stephanie N. Phillips Kurt W. Limesand John W. Lane, Jr. 2020 publication USA U.S.Geological Survey XXXXXXX In June 2018, the 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, Missouri. Geophysical methods were used to evaluate and characterize the unconsolidated sediment (i.e., regolith) above the crystalline bedrock as well as determine depth bedrock. Land-based geophysical methods included frequency domain electromagnetic induction (FDEM), electrical resistivity tomography (ERT), horizontal-to-vertical spectral ratio passive seismic (HVSR), and shear-wave seismic refraction. Water-borne methods included FDEM surveys to characterize the Fredericktown City Lake sediments as well as forward-looking infrared (FLIR) imagery taken along the City Lake shoreline to identify locations of potential groundwater-surface water interactions. These geophysical data were collected to help characterize the unconsolidated sediments above and 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 Support is provided for correcting errors in the data release and clarification of the study conducted by the U.S. Geological Survey.
