New Water Supplies; Aquifer Sensitivity

New water supply site surveys and analysis of water supply sensitivity to pollution and over-pumping including specification of the 3D geometry and hydrogeologic properties of the geologic stratigraphy. We collect and analyze geophysical data, sediment cores as needed, and pertinent physical and geochemical properties of site materials. More Information

Wetland/Peatland Functioning

Analysis of the extent, content, and surface-ground water interaction within wetlands/peatlands. We specify the geometry and hydrogeologic properties of the geology beneath the wetland/peatland and also the physical structure of the wetland/peatland itself. We collect and analyze geophysical data, peat sediment cores as needed, and pertinent physical and geochemical properties (e.g., water and carbon content) of site materials. More Information

Sediment Prospecting for Aggregate

Analysis of the properties and volumes of sediment types in the specified area including specification of the 3D geometry of the deposits. Collection and analysis of geophysical data, of sediment cores as needed, and of sediment physical properties. More Information

Karst Hazard Analysis

Sinkhole hazard analysis including a comprehensive sinkhole inventory which identifies and characterizes existing sinkholes and prediction models for future sinkhole development. We collect and analyze geophysical data, sediment cores as needed, and laboratory data on pertinent material physical properties. More Information

Stability of Roads, Bridges, Dams, Slopes

  Analysis of the physical properties of secondary highway grade and subgrade layers including thickness, content, strength, and deformation. Analysis of small bridge and dam deterioration including corrosion, fractures, and voids. Analysis of slope stability including overburden thickness and zones of weakness that have slide hazard. We collect and analyze geophysical data, sediment cores as needed, and pertinent physical and geochemical properties of site materials. More Information

Utility Location

Locations, maps and cross-sections with subsurface utility lines (power, water, sewer, fuel) and storage tanks based on non-invasive geophysical methods.

Geophysics of Archaeological Sites

3D models of geologic materials within archaeological structures. Deliverables include maps and cross-sections of the features of interest, geophysical data, description of cores if collected, pertinent analyses of core samples, and summary interpretations.
