The Possible Use of Tritium' for Estimating Groundwater Storage

In view of a recent work by Begemann & Libby (1957) their postulate on rapid mixing inside a groundwater body is examined. It is found that there are no possible processes which can accomplish such a mixing. Their observations can, however, be readily explained from a simple model of groundwater flow, assuming no mixing. Possible methods of using tracers like tritium for estimating groundwater storage are also discussed. DOI: 10.1111/j.2153-3490.1958.tb02035.x
