Radiocarbon 14 C is useful for estimating groundwater ages for transport and water resource exploitation assessment.
If the 14 C content of dissolved inorganic carbon 14 C DIC is known, the age of groundwater can be estimated by applying a radiocarbon decay equation combined with an appropriate geochemical correction model. However, age determinations are subject to uncertainties caused by parameters which need to be estimated or assumed.
Here, we discuss the principles of 14 C-based groundwater age estimations and the corrections and errors that affect age determinations differently. Generally, the two factors that impact the of 14 C groundwater age are Type-1 and Type-2 errors. Type-1 errors Radiocarbon dating water pulse-type changes on derived groundwater ages that are independent of the water age. Type-2 errors cause gradual changes on derived groundwater 14 C ages that depend on the water age. The cumulative impact of these errors substantively reduces the accuracy and confidence of 14 C age determinations and corrections.
