This is a case history of a pilot test which has been performed in the NE of Italy to detect and monitor the sub-surface behaviour of a salt-water solution within a sand-gravel aquifer. ERT (Earth Resistivity Tomography) was used. The experiment consisted in pumping a of saltwater solution - which presents a low resistivity value - into a well, in order to detect variations of resistivity vs. time during the flow of the solution within the aquifer.
