Chlorine has two stable isotopes and one cosmogenic isotope the cosmogenic isotope, 36 cl, has a long half-life, making it useful in age dating groundwaters up to 1 million years old there is also limited variation in 37 cl most natural variation in 37 cl values in hydrologic systems are related to diffusion processes. Very old groundwater this paper demonstrates the first use of atta for groundwater dating by the 81kr methodthe nubian aquifer of the western desert of egypt [thorweihe. The groundwater is confined and discharges by both upward and downward leakage through the shales the concentration of cl - increases by about 2 orders of magnitude downgradient through the aquifer this cl - increase complicates 36 cl dating of the system.

Chlorine 36 has many advantages as a dating tool for very old groundwater these advantages include a suitable half-life (301 × 10 5 years), simple geochemistry, conservative behavior in groundwater, and a general absence of subsurface sources at levels comparable to the atmospheric input.

36 cl has been applied to the dating of very old groundwater in regions such as the atlantic coastal plain, maryland, usa [19 plummer ln, eggleston jr, andreasen dc, raffensperger jp, hunt ag, casile gc.

Thermonuclear 36 cl is likely to become more frequently used as an indicator of young water as the thermonuclear 3 h in ground water decays to background levels over the next couple decades 36 cl has been used to date old ground water in confined aquifers by consideration of the affect of radioactive decay on measured 36 cl/cl ratios (bentley.
