Environmental tracers age dating young groundwater
Carbon-14 is used to date groundwater older than 1000 years. Various environmental isotopes and tracers are used to determine the age of groundwater.
Carbon-14 is used to date groundwater older than 1000 years.
Because the half-life of carbon-14 is long (5,730 years), this method is useful for determining the age of groundwater between about 1,000 and 30,000 years old.A common complication of carbon-14 dating is the introduction of additional, carbon-14–free carbon (carbon containing no carbon-14) from the aquifer.
