A hydrogechemical and hydrogeological study was carried out in the plain of the Verdura River Ribera, Province of Agrigento) to define the water quality and a model of subterranean circulation. From a hydrogeological point of view, several complexes are present. The piezometric map permitted to understand the underground circulation mechanisms in the main aquifer and the inter-relationships with the surface one. The chemical water analyses showed that the waters belong to two mainly groups: chloride-sulfate earth alkaline and chloride-sulfate alkaline types. The two groups are not completely distinct, in fact some samples have chemical composition in between. The isotope compositions clearly show that waters are of meteoric origin, although they don't fit on the GMWL or MMWL lines. Finally, no seawater intrusion is present at moment.
