CÓZ-rich springs and wells in the Campo de Calatrava commonly are named Hervideros. This .ground
water is originated by deep circulation along the fractures of the paleozoic rocks of the area, with residence
times longer than 15years. The hydrochemical facies is miked-catipn bicarbonate and is related to the
extinct yolcanism 6f the area. It is a possibility that not all the Hervideros are originated from volcapic or . >
magmatic C02. Bacterial evaluation indicates high values, but probably it is representative of the-biomass
presence in the proper sampling point instead of the groundwater-microbiology
