District Po — Groundwater bodies

Groundwater bodies of the Po River District Management Plan drawn up in accordance with the European Directive 2000/60/EC. They concern, as defined in the Directive, all waters below the surface of the soil in the saturation zone and in direct contact with the soil or subsoil. A body of groundwater is defined, again by the Directive, as a separate volume of groundwater contained in one or more aquifers (in turn defined as one or more underground layers of rock or other geological strata of porosity and permeability sufficient to allow a significant flow of groundwater or the extraction of significant amounts of groundwater). Several circulation systems have been identified in the Po River District in the plain area: ground system, surface system, deep system. For hill and mountain areas, water bodies (hill-mountain system) were identified in the same dataset as the plain surface system.
