COST EFFECTIVE AND HIGH RESOLUTION SUBSURFACE CHARACTERIZATION USING HYDRAULIC TOMOGRAPHY

Abstract

Hydraulic Tomography (HT) is a high-resolution technology for delineating the spatial distribution of hydraulic conductivity (K) and specific storage (Ss) parameters, which critically affect the performance of subsurface remedial actions at environmental sites. The good technical performance and cost-effectiveness of HT have been demonstrated in this project at two field sites: (1) a local-scale site at a spatial resolution critical to typical source zone remedial actions and (2) a field-scale site typical of Department of Defense (DoD) environmental sites. This project: 1) demonstrated that HT is superior to conventional methods for estimating the spatial distribution of hydrogeologic properties; 2) illustrated that an HT survey can be readily conducted at DoD sites using existing networks of groundwater extraction/injection and observation wells; and 3) developed guidance for HT field implementation and compare costs associated with HT and conventional methods.
