Chlorine (36Cl) is an isotope...

The 36 Cl used for this purpose is produced in the atmosphere through the interaction of cosmic rays with argon atoms. The 36 Cl then mixes with ordinary atmospheric chloride mostly derived from the ocean.

The minimum treatment requirement for...

The mixture is deposited on the land surface dissolved in rain or snow or as dry aerosols. Chloride is conservative in the subsurface and, thus, the 36 Cl is rarely retarded with respect to the water velocity by adsorption or geochemical reactions.

Groundwater age can be estimated using the radiometric decay equation and the decrease in 36 Cl from the amount in the recharge water. The main complication is variations in the Cl concentration of groundwater. This can potentially be due to variable evapotranspiration during recharge or to the Chlorine 36 hookup of very old groundwater of Cl in the aquifer.

The minimum treatment requirement for...

If the cause of Cl concentration variations is understood, the age calculation can be corrected to account for the process. Chlorine dating is generally applicable to water in the age range ka—1 Ma.
