Results of the chemical and isotopic studies from springs, domestic and geothermal wells in Las Tres Virgenes, B.C.S. are presented. Three water types were found to be in the study zone. Sulphate-type water at the North, bicarbonate-type waters at the South and sodium chloride type at the West. The last group includes the reservoir water. The estimated geothermometric temperature for the LV-1 well was 259°C with CCG geothermometer, while the estimated temperature for the springs were low, due to high dilution of the deep fluid with groundwater. The isotopic data (d18O and dD) were used to define the local meteoric line, the isotopic composition of the reservoir recharge and the possible elevation where the reservoir recharge is likely to occur. Finally a discussion about the possible origin of the geothermal water based on the isotopic data is presented.
