Geo-electrical tomography and electromagnetical profiling as an effective scanning tool for detecting and defining groundwater contamination and monitoring of remediation

abstract
The traditional method for the investigation of soil and groundwater pollution consists in drilling to take soil samples, mostly followed by placing piezometers to take groundwater samples. Next, the soil and groundwater samples are analysed to deduce the quality. Unfortunately, a large number of drillings are necessary to detect the location and the depth of the source of pollution or to define the lateral and vertical extension of the pollution plume because the drillings are placed more of less ad random and only provide single point information at selected depths. Therefore, a fast and reliable procedure to detect and delineate the pollution is required prior to the installation of the piezometers. Geophysical methods (electromagnetical profiling and geo-electrical tomography) are proposed to deduce the extension of the pollution in the first place and secondly to monitor the effectiveness of the remediation of the pollution. The applicability of this method relies on the condition that the contamination, due to spills, leakage or discharges, causes a significant difference in conductivity/resistivity. Based on the geophysical survey a more directed installation of piezometers and a more efficient groundwater sampling are possible. To examine the effectiveness of the sanitation of pollution, electrical and electromagnetical investigation can be used successfully, because the conductivity will change through the sanitation. This can be considered as an innovative approach. The methodology of the implementation of electromagnetical and geo-electrical survey is explained based on real field cases.
