As is widely recognized, and discussed in considerable detail throughout the scientific literature, there are many hydrogeochemical reactions and/or physical processes that can alter the natural C enrichment measured in environmental materials.
Although C dating of groundwater can be, and often is, carried out as a matter of routine, any specific case study requires its own scientific design and effort.
In contrast, only a few groundwater ages can be provided for the calibration of those models that are complex functions of aging mixture and sometimes also hydrochemical reactions.
The hydraulic properties of each of the widely used finite-element models can be well estimated from numerous piezometric data and extrapolations.
