We propose a statistical approach to the study of subsoil thermal data in order to find an equation able to describe the temperature distribution in the underground of the Piedmont plain sectors (NW Italy). The analytical model here proposed, can be used during the preliminary stage of investigation for the exploitation of subsoil by means of low enthalpy geothermal plants. The statistical analysis was performed using groundwater thermometric data from thermal logs collected in boreholes crossing the Quaternary fluvial deposits hosting a shallow aquifer.
