The use of ERT for the characterization of a thermal karstic aquifer

This is a case history of an ERT survey in a karstic aquifer characterized by the presence of thermal water having a temperature > 35° C. The aim of this survey was to define the best position of a well for exploiting thermal water, in order to restore the old thermal bath. ERT was used to define: o The depth and the morphology of the carbonated bedrock o Different aquifer features o Thermal water concentration The positioning of the well defined by the ERT survey result was successful. Thermal data logging agreed with the ERT model.
