Ground-water dating to assess aquifer susceptibility the age of ground water is defined as the time since the water was recharged and isolated from the atmosphere.
Simply put, the underlying principle with groundwater age-dating is that once water has recharged the subsurface, how old is our groundwater. Argon-39 can be used as a tracer for age-dating glaciers, oceans, and more recently, groundwater with a half-life of 269 years, 39 ar fills an intermediate age range gap (50–1,000 years) not currently covered by other common groundwater tracers.
