Influencia de los eventos de recarga en la hidrogeoquímica del acuífero del Ventós-Castellar (Alicante)

Abstract

The Ventós-Castellar aquifer is a small karstic system situated in Alicante province in the Southeast of Spain. Nowdays this aquifer is exploted by just one well which water is carried to supply a small town. In the last years, this aquifer has been monitored for several parameters, including chemical composition, in order to establish its hydrogeochemistry and also the influence of recharge events on it. The hydrogeochemistry results have shown that calcium and bicarbonates are the main ions, but sulphates and chlorides are high as well. Some rainfall events lead to significant recharge in the aquifer which make a dilution. Dilution is proportional to the entrances in the aquifer. The hydrogeochemical data could be useful in defining of the infiltration rate, the water reseves, the hydrodinamic functioning and, basically, the conceptual model of this aquifer.
