Abstract | Groundwater dating on 14C of dissolved inorganic carbon (DIC) requires identification of the source term indicative of the groundwater age, i.e. the portion of DIC in a groundwater introduced by recharge. Quantification of DIC from other sources is made mainly by means of the δ13C value. On mineralization of sedimentary organic carbon (SOS), the δ13C value of DIC generated cannot be distinguished from the source term, i.e. soil CO2. In a groundwater where mineralization of SOC has occurred, the source term therefore cannot be identified by the δ13 value of DIC. Furthermore, if the occurrence of mineralization of SOC is not recognized or is ignored, evaluation of the source term on the basis of the δ13 value leads to overestimation of the groundwater age |
