The evaluation of good qualitative and quantitative status of groundwater (WFD requirement) needs a comprehensive estimation of the short and long term trends in order to establish adequate river basin management plans. In this context, the understanding of surface water/ groundwater interactions is required for water quantity and quality preservation. Hydrogeochemistry permits characterizing water and dissolved element origin and flow in both ground and surface water.
