A1 Ruano Magán, Pedro A1 Senderos Domínguez, Agustín Jesús A1 Villarroya Gil, Fermín AB CO2-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 15 years. The hydrochemical facies is mixed-cation bicarbonate and is related to the extinct volcanism of the area. It is a possibility that not all the Hervideros are originated from volcanic 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 PB Sociedad Geológica de España SN 0213-683X YR 1999 FD 1999 LK https://hdl.handle.net/20.500.14352/112433 UL https://hdl.handle.net/20.500.14352/112433 LA spa NO Yélamos, J.G. et al.
