In the diagnosis of soils that have been contaminated with dangerous substances after remediation, it is usual to make wells in the contaminated area, in order to extract samples for analysis that allow to determine the extension and depth of the soil contamination level. This research intends to demonstrate that this diagnosis after remediation can also be done with non invasive techniques, with cost and time reduction, and avoiding the sample cross contamination risks of the invasive method. The non invasive methods used in this particular case of accidental contamination with concentrated sulphuric acid were Electromagnetic Induction (EMI) and Geoelectric. According to the results, it may be concluded that the complementary use of both methods allow to make a correct diagnosis of the remediation effectiveness.
