摘要

A concept has been developed that enables the identification of the source of a ground-water contamination. Environmental isotope methods (stable isotopes, tritium, ~3He) are used to describe the hydrogeological system, to obtain representative and accurate hydrogeological parameters in a case study where the location, time and duration of an input of soluble organochlorine compounds to the groundwater has to be identified. The practical application of the concept is demonstrated. In this special case, isotope methods lead, for example, to a decrease of the variability of the piston velocity of the groundwater from about one order of magnitude (derived from standard methods) to about ±25% standard deviation from a representative average of the piston velocity in the entire investigation area.
