Monitoring Tracer Experiments at the Krauthausen Test Site Using Time-Lapse ERT

P007 MONITORING TRACER EXPERIMENTS AT THE KRAUTHAUSEN TEST SITE USING TIME- LAPSE ERT Abstract 1 Time-lapse electrical resistance tomography (ERT) has proven significant potential to image solute plumes in the subsurface. We here report on the use of time-lapse ERT to monitor two tracer experiments conducted in a heterogeneous aquifer at the Krauthausen test site Germany. The two experiments were carried out under similar hydrological boundary conditions but one time with an electrically conductive (“positive”) tracer the other time with a resistive (“negative”) tracer. Based on earlier synthetic studies on the capability of 2D ERT imaging to characterize 3D transport
