Abstract : The C14 method is a useful addition to the techniques available for the study of ground water hydrology. To use it successfully requires an understanding of the carbonate chemistry of the systems being investigated. To adjust C14 measurements the proportion of soil air to aquifier-derived carbonate species must be known. In systems in which marine limestone is the only carbonate derived from the aquifer, delta C13 values of the dissolved carbonate can be used to determine this proportion directly. Carbon-14 measurements are useful in studying not only ground water flow rates but the rates of physical and chemical processes occurring in ground water systems.
