Hydrogeological map of the Monti Picentini Regional Park (southern Italy) at 1: 50,000 scale

Calcareous and calcareous-dolomitic reliefs form the backbone of the Monti Picentini Regional Park. A possible subdivision of the groundwater bodies of the area into hydrogeological basins was proposed: for each basin the stratigraphy and structure as well as the scheme of groundwater circulation were drawn up. Many basins fall only partly within the park and most of their groundwater often ends up outside the area in question; the Terminio-Tuoro mountains, for example, feed large springs (Cassano Irpino group, Serino springs, etc.) that are all outside the park boundaries. Using integrated hydrogeological data analysis, we defined the main aspects of aquifer vulnerability to pollution and identified the factors that may locally increase the risk of resource contamination. Finally, the effective recharge of the various groundwater bodies was evaluated.
