After oxidation to HTO, it takes part in the natural water cycle.Before the full potential of natural tritium as a tracer for water movement in natural systems could be explored its distribution was masked by addition of large amounts of so-called ‘bomb tritium’ produced during the surface tests of nuclear weapons.Hydrologists employ a variety of techniques to measure groundwater age.

Determination of the H in the water sample (Schlosser et al., 1988, 1989). Whereas the addition of bomb tritium to the environment practically eliminated the use of natural tritium as a tracer, it offered a new tool, i.e., the use of the bomb tritium peak (Fig.1) as a ‘dye’ that is delivered to natural water systems from the atmosphere on local to global scales.CFCs are human-made compounds that are stable in the environment.Atmospheric CFC concentrations increased from the time of their development in the 1930s until the 1990s, and hydrologists now know how atmospheric CFC concentrations have changed over time.
