One liter of water with a concentration of 1 TU produces 7.2 disintegrations per minute(dpm) or 0.12 becquerel (Bq); one Bq corresponds to 1 disintegration per second (dps);one curie (Ci) is equal to 3.7x10 Bq.] Additional He sources, terrigenic He, may be present in aquifers where the rocks are enriched in U or Th, or in ground-water samples in which young water has mixed with relatively old water containing terrigenic He.

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

This increased reliance on the groundwater in concert with the strict regulation on water quality has led to a need by water managers and regulators to understand: Characterization of mean groundwater age and recharge temperature through the use of noble gas techniques provides information that is relevant to answering these questions and that is not accessible through traditional hydrogeologic approaches.

In systems younger than the mid-1960s, the bomb peak will not be present due to radioactive decay.

Although initial H input to ground water and may be used to determine the position of the mid-1960s bomb peak in recharge areas.

1) as a ‘dye’ that is delivered to natural water systems from the atmosphere on local to global scales.

If the tritium delivery as a function of time can be reconstructed, this penetration process can be used for quantitative studies of water movement through identification of the bomb peak in certain ground water bodies.

The Water Dating Lab at GNS has 55 years of experience in high-sensitivity tritium analysis.

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

Determination of the H in the water sample (Schlosser et al., 1988, 1989).
