The analyses of stable isotopes δ2H and δ18O have great significance in the groundwater studies, particularly to understand the mixing of surface and groundwater. How the stable isotope studies help in comprehending the mechanism of fluoride mobilization in groundwater?

Dear Dr Arvind Singh,
You have provided links and attached papers on the said topic. All these would be highly useful to understand the subject.
I am highly thankful to you. Hope, I will get cooperation from you in future also.
Regards - Dr Asit
All waters have "fingerprints" of naturally occurring isotopes that provide information about their origin. Among the most powerful and cost-effective fingerprinting tools are the ratios of stable isotopes of hydrogen--deuterium to hydrogen (D/H)--and of oxygen-18 to oxygen-16 (18O/16O). For example, the D/H and 18O/16O ratios in precipitation vary according to elevation and distance from the ocean. An altitude difference of 250 meters produces a clear and measurable change in the two ratios, which is preserved once the precipitation infiltrates to the aquifer.
The stable (2H, 18O) isotopes in integration with radioactive (3H, 14C) can provide detailed insight into and assess the mean groundwater recharge in river basins, regional groundwater flow velocity and residence time, contamination characteristics, flow-paths of intermixing, and identification and delineation of recharging zones and protection zones in the aquifer system. The D/H and 18O/16O ratios can be used also to discriminate among multiple water sources within an aquifer.
Dr. P. S. Datta - Sir, You have provided important information on the use of stable isotopes in groundwater studies. I may place some other questions on isotopes - I expect your vauable comments. I am highly thankful to you. With best regards - Dr. Asit
Sir, I am working on Groundwater hydrology and my major concern is on stable isotopes analysis.
My question is that how can we interpret stable isotopes data sir ? I have read so many research paper , but couldn't find enough answer.
