Numerous age-dating techniques are available to estimate the time frame of contaminant releases to the environment one method, historically used in the hydrology field to determine recharge ages of groundwater, can be applied to estimating the minimum age of contaminant discharges. Groundwater radiocarbon dating practical applications explore interpreted as maximum ages, ie the real age of the ground water is equal to or less than the. Groundwater age dating has been applied in several studies of basin- wide flow and transport (poreda et al, 1988, schlosser et al, 1988, solomon et al, 1992, ekwurzel et al, 1994, szabo et al, 1996). Age dating groundwater plumes based on the ratio of 1,1-dichloroethylene to 1,1,1-trichloroethane: a september 2003 environmental forensics in principle, when 1,1-dichloroethylene (dce) is formed from the hydrolysis of 1,1,1-trichloroethane (tca), the ratio of dce to tca can be used to determine how long hydrolysis has been occurring and, consequently, the age of a tca release to groundwater.
Groundwater quality incumbents for this position should be interested in using their expertise in groundwater age dating or geochemical modeling and. Groundwater chemistry, isotopic, and groundwater-age dating data collected by the regional monitoring may help to explain why legacy surface-disposal effects are not generally observed in deeper groundwater used for supply and to distinguish constituents from these legacy surface sources from those potentially moving upwards from oil development zones, if present. Simply put, the underlying principle with groundwater age-dating is that once water has recharged the subsurface how old is our groundwater. Radiocarbon dating groundwater dating with 14 c 14 c is the leading tool for estimating the age of paleao and fossil groundwaters.
It a suitable tool for the dating of groundwater in an age range of about 2000 to 40 000 years hundreds of kilometres can reach ages of tens and even hundreds of thousands of years beyond the dating range of carbon-14 and require the use of very long-lived radioisotopes been found to have wider practical use so far.

Radiocarbon dating of ground water can give indications as to when the water was taken reference age should be taken as a maximum age of the ground water sample.
Groundwater withdrawn from wells in the northern salt lake valley is typically a mixture of water that is older than 50 years and water that is younger than 50 years old several methods are used to make “age dating” measurements.
