Underground water dating and age corrections using radiocarbon

This paper describe a method that correlate underground water dating using radiocarbon and other environmental isotopes in order to estimate recharge conditions of an aquifer located in Romania. Radiocarbon ages were corrected by six correction models. Obtained data conducted to a mean transit velocity of studied aquifer of 0.55 m/year, value which is specific for this type of aquifer. Although radiocarbon measurement method proposed in this paper is a classical one, optimizations to the preparation technique allow reduction of time and financial costs and can be successfully applied to a large number of samples, common in hydrological studies.
