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.
This system represents a capability for characterizing groundwater recharge conditions by dissolved gas analysis that is unmatched by any other laboratory.

The increasing national and international demand for water has led to increasing reliance on subsurface storage, both for naturally and artificially recharged water.
The results showed that the distance of the wells from the bank of the lake does not affect the calculated ages, especially for the deep wells where all deep wells have nearly the same age.
The shallow wells, which have ages nearly one year, have stable tritium of 11-12 TU, while the deep wells with ages nearly 24 years have stable tritium of 15-25 TU.
The concentrations of tritium, helium isotopes and neon have been measured in groundwater samples from a shallow and deep groundwater system recharged by bank infiltration from the Oder River in northeastern Berlin, Germany.
