Geological / Groundwater Evaluation Projects
Geophysical Survey: Prepared and submitted preliminary site investigation request and detailed site investigation (DSI) work plan to the Missouri Department of Natural Resources-Geological Survey Program (MDNR-GSP) for a proposed 40-acre utility waste landfill within the New Madrid Seismic Zone of Scott County, Missouri. Services included the planning and oversight of a comprehensive geophysical survey for the initial phase of the DSI, which consisted of ground penetrating radar (GPR) technology to identify potential morphoseismic features (caused by liquefaction). Services also included the excavation and description of verification soil test pits and the GPR survey report preparation for submittal to the MDNR-GSP.
Groundwater Monitoring & Statistical Analysis: Services provided included the collection of quarterly groundwater samples, water quality analytical review, and groundwater monitoring reports of the 36 monitoring well network at the Ameren Missouri Labadie Energy Center's utility waste landfill. Services also included the preparation of a Sampling and Analysis Plan (SAP) and the statistical analysis of eight rounds of background water quality data.
Karst Assessment: Provided a professional opinion concerning an impoundment (i.e., pond) located on a property in Boone County, Missouri to determine if the impoundment was an actual karst-related sinkhole. The karst assessment was a requirement of the county health department for the permit approval of an onsite wastewater treatment system (OWTS) to serve a proposed single-family residence that was geologically mapped in the Burlington-Keokuk Limestone bedrock, where sinkhole development is extensive. Services included a site evaluation, geological literature review and letter report regarding the site.
