“…Tritium concentrations for group I (5.1-12.5 TU) are essentially the same as those for group III or surface water (4.7-15.5 TU) but are significantly higher than those for group II (1.4-3.3 TU) ( Table 2). Tritium levels are typically not detected or very low (<1.0 TU) in concentrated CO 2 -rich water and any detection of tritium in those groundwaters is generally explained by mixing with shallow groundwaters recently recharged (Pauwels & Fouillac 1997;Aires-Barros et al 1998;Federico et al 2002;Simsek 2003;Okan & Ç etindag 2005). The appreciable TU levels in group II waters suggest that they were diluted with young shallow water, perhaps because the wells have long open intervals in the bedrock.…”

A geochemical study was carried out on the CO 2 -rich water occurring in granite areas of Chungcheong Province, Korea. In this area, very dilute and acidic CO 2 -rich waters [62-242 mg l )1 in total dissolved solid (TDS), 4.0-5.3 in pH; group I) occur together with normal CO 2 -rich waters (317-988 mg l )1 in TDS, 5.5-6.0 in pH; group II). The concentration levels and ages of group I water are similar to those of recently recharged and low-mineralized groundwater (group III). Calculation of reaction pathways suggests that group I waters are produced by direct influx of CO 2 gas into group III type waters. When the groundwater is injected with CO 2 , it develops the capacity to accept dissolved solids and it can evolve into water with very high solute concentrations. Whether the water is open or closed to the CO 2 gases becomes less important in controlling the reaction pathway of the CO 2 -rich groundwater when the initial pCO 2 is high. Our data show that most of the solutes are dissolved in the CO 2 -rich groundwater at pH > 5 where the weathering rates of silicates are very slow or independent of pH. Thus, groundwater age is likely more important in developing high solute concentrations in the CO 2 -rich groundwaters than accelerated weathering kinetics because of acidic pH caused by high pCO 2 .
