Indagine idrogeochimica di un area intensamente coltivata della Sicilia sud-occidentale

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 clearl…
