In 2002, an accidental release of unlead gasoline from a ruptured underground storage tank of a gas station has contaminated soils and groundwater. Although remediation actions have taken place, groundwater is still contaminated. During the last year, hydrogeological and geophysical investigations have been carried out in the area between the gas station and the local river, for site characterisation. The hydrogeological survey aimed at defining the groundwater flow and eventual tectonic control. The geophysical survey consisted of EM31 and 34, GPR, Resistivity and IP, so that a more complete diagnosis of the situation could be conducted.
