Abstract

Traditional methods for mapping possible flowpaths of contaminants in sedimentary environments by boreholes may often be insufficient. Additional information may be acquired by geophysical methods. In the present study, cross-borehole and surface measurements were performed using time-domain induced polarization (TDiP). After measurements the entire test site was dug out, and the geology was described. Despite of being above the groundwater table, it was possible to retrieve exceptionally well the distribution of sand lenses/layers at the site, with clear signature in both the DC conductivity and the IP parameters, as confirmed by the excavations carried out for verifying the geophysical results. Consequently, cross-hole TDiP imaging is a valuable tool for characterizing possible flowpaths of contaminants in in clayey moraines.
