Tritium water dating

Therefore, for quantitative studies, mixing has either to be ruled out as a major factor influencing the flow regime or it has to be accounted for in the data evaluation.Significant differences between the apparent tritium/ is mainly determined by the ratio of advection to dispersion in water parcels moving away from the water table.The approach was tested in three adjacent caves in northwestern Germany which were monitored for about two years.All of the studied drip sites yielded drip water ages between 2 and 4 years with uncertainties on the order of 1 year.One TU (Tritium Unit) means a tritium to hydrogen ratio of 10.

The increasing national and international demand for water has led to increasing reliance on subsurface storage, both for naturally and artificially recharged water.

In contrast to traditional tritium dating, we do not refer directly to tritium concentrations in precipitation as input function, but to an infiltration-weighted annual mean of the rainwater values.

Using concentration differences between this infiltration-weighted mean and the drip water, an age is calculated from the radioactive decay law, assuming piston flow.

Our innovative, cutting edge techniques give by a large margin the highest accuracy and precision in tritium analysis [1].

Our tracer data are used to understand and manage groundwater resources, and to understand how groundwater dynamics change over time.

The fully automated, computer-controlled manifold system allows analysis of the full suite of noble gases (3He/4He, He, Ne, Ar, Kr, and Xe concentrations), along with low level tritium for reporting of derived quantities that include tritium/helium-3 groundwater age, noble gas recharge temperature, and dissolved excess air concentration.
