Suspension-log data are typically used for engineering and seismic studies in shallow unconsolidated sediments. At the USDOE Savannah River Site, suspension data were acquired in a series of deep boreholes (up to ∼400 m) to support high-resolution

Geophysical methods, including a shallow seismic reflection (SSR) survey, surface and borehole ground-penetrating radar (GPR) data, and electrical resistivity imaging (ERI), were conducted at the Savannah River site (SRS), South Carolina, to investig

As part of a multiscale hydrogeophysical and modeling study, a pseudo three-dimensional (3-D) seismic survey was conducted over a contaminant plume at P area, Savannah River site (South Carolina), to enhance the existing geologic model by resolving u

This paper presents a case study using various geophysical techniques in unconsolidated sediments where shallow faulting is probable and most likely affects ground-water flow. Wenner and dipole-dipole resistivity, ground penetrating radar (GPR), and

Borehole dilution tests have been used for characterization of aquifer hydrogeologic properties for several decades. Based on the principles of borehole dilution tests, we conducted what more appropriately may be considered a wellbore fluid displacem

Summary High-resolution seismic reflection data and AVO analysis were used to locate high concentrations of dense nonaqueous phase (DNAPL) contaminants at the Charleston Naval Weapons Station Solid Waste Management Unit 12 (SWMU-12) near Charleston,

Recent advances in seismic reflection amplitude analysis (e.g., amplitude versus offset-AVO, bright spot mapping) technology to directly detect the presence of subsurface DNAPL (e.g., CCl4) were applied to 216–Z-9 crib, 200 West Area, DOE Hanford S
