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 extractioninjection and observation wells and 3 developed guidance for HT field implementation and compare costs associated with HT and conventional methods.
