Summary:
We present the results of the geoelectric and electromagnetic induction methods applied to detect and delimit an area contaminated with hydrocarbons. The joint implementation of these methods was performed in order to enhance the resolution of the prospecting, since each method presents different sensitivity and resolution according to the physical properties of the materials. On the basis of the results of this study, stabilization/solidification methods were applied to remedy the contaminated area. Additional surveys were performed immediately after remediation showing that the contaminants were effectively encapsulated.
