<p>Soil pollution by landfill leachate is a major environmental problem that poses risks to human health and the ecosystem. Cost-efficient methods for detection of the position, extension and geometry of the leachate plume are in high demand for mitigation/remediation programs. In this study, sets of multi-profile laboratory-scale electrical resistivity (ER) measurements using two well-known arrays were conducted. An anomaly, representing an underground leachate plume with less resistivity than surrounding soil was placed slanted inside a sandy environment with higher resistivity. The geometry, and position was planned to be detected through 2D and 3D inverted graphical demonstrations. The ER measurements were conducted in 15 parallel lines, each consisting of 16 electrodes. To obtain reliable resistivity sections after inversion, two types of raw and corrected measured resistivity values was used in inversion. The measured dataset was corrected in order to consider the effect of the finite boundaries of the setup, using modeled 3D effects as a function of electrode spacing. When cycling through 15 inverted resistivity sections, the reposition of the anomaly zone in horizontal and vertical directions can be observed clearly. The accuracy of anomaly location and geometry is not significantly improved in extended inversed model compared to standard model. But changing of the parameters used in the inversion process makes the results even more clear and reliable. The results show that both 2D and 3D laboratory-scale ER measurements are promising methods to map less resistive anomaly plumes in soils. Moreover, it has the potential to improve the resolution of obtained resistivity sections. Schlumberger array was also found to produce better resolution in inverted resistivity sections.</p>
