Looking beyond sf6 in addition to groundwater dating, trace halogenated compounds are beginning to be used as source tracers many human activities. Knowing the residence time of groundwater can be of importance in understanding key issues in the evolution of water quality chlorofluorocarbons (cfcs) and sulphur hexafluoride (sf 6) offer a convenient way of dating waters up to ∼60 yrs old although any one of these gases can in principle.
