Use of discrete-zone monitoring systems for hydraulic characterization of a fractured-rock aquifer at the University of Connecticut Landfill, Storrs, Connecticut, 1999 to 2002Johnson, Carole D.; Kochiss, Christopher S.; Dawson, C.B.
An integrated surface-geophysical investigation of the University of Connecticut landfill, Storrs, Connecticut, 2000
A surface-geophysical investigation to characterize the hydrogeology and contaminant distribution of the former landfill area at the University of Connecticut in Storrs, Connecticut, was conducted in 2000 to supplement the preliminary hydrogeologic assessment of the contamination of soil, surface water, and ground water at the site. A geophysical-...Johnson, Carole D.; Dawson, C.B.; Belaval, Marcel; Lane, John W.
This video provides an overvew of the USGS Scenario Evaluator for Electrical Resistivity (SEER).
Today’s environmental site managers have many tools to choose from when conducting site characterization and remediation. Geophysical tools can provide noninvasive ways to see inside the earth, much like how medical imaging lets us see inside the human body. The USGS...
Borehole nuclear magnetic resonance (NMR) is an emerging geophysical method being applied to hydrogeology investigations. NMR is a quantitative geophysical method that can be used to make in situ assessments of porosity, water content, mobile and immobile water fraction, and estimates of permeability. While borehole NMR is commonly used in the oil and gas industry, it is...
This video provides an overview of the USGS Fractured Rock Geophysical Toolbox Method Selection Tool. The Fractured Rock Geophysical Toolbox Method Selection Tool (FRGT-MST) is an Excel-based tool for identification of geophysical methods most likely to be appropriate for project goals and site conditions. We envision the FRGT-MST: 1) equipping remediation professionals...
