Electrical geophysical exploration for environmental risk assessment: characterisation and monitoring of landfill sites

The geophysical prospecting methods are able to reconstruct detailed physical and geometrical images of hidden volumes from surface measurements. In the last 20 years, they were successfully applied in environmental field, implying the identification of anomalous space variations of physical parameters, attributable to pollution phenomena inside soils and/or aquifers. In particular, the seminar was focused on the application of the electrical geophysical methodologies in the landfill site study. A brief scientific and technical description of some electrical geophysical techniques were provided as well as the methodological justification of their application in the landfill research field. Examples coming from old and/or active landfill sites have been presented and discussed. Finally, some details on monitoring geophysical techniques of areas interested by pollutant fluid infiltrations were also supplied
