To determine the residence time of groundwater in arid, semi-arid, and humid regions, transient tracers such as tritium () have been widely used (Busenberg and Plummer 1992, 2000, IAEA 2006).

However, few studies have used such tracers in the cryolithic region.

They analyzed the role of permafrost thawing in the water balance of a growing thermokarst lake, and showed melting of ground ice has significantly contributed to lake growth (30–35% to the lake water increase).Detection of changes in the hydrological cycles of permafrost regions is a critical issue in hydrology.Better understanding of groundwater dynamics in permafrost regions is needed to assess the vulnerability of the cryolithic water environment to changing climate.Comparisons of apparent groundwater ages estimated from different tracers imply that H and CFC-12 are the most applicable to groundwater vulnerability assessments in this region.Because the apparent age is a mixture of those from supra-permafrost and intra-permafrost groundwater, further analysis would be required to assess the contribution ratio of the two types of groundwater.
