Abstract :

Ground waters are one of the largest and available fresh water for human use. While two-thirds of the surface area of the earth covered with water, the main part is sea water or saltwater and just 2.5% is fresh water. In the renewable and non renewable table of groundwater, for 95% of fresh water and 7% of total waters is available. Isotope techniques can be used for determination of the age of underground waters and system process. The use of the ager of underground water for estimate aquifer storage, refresh rate of groundwater, and flue rate by Tritium (natural radioactive) and 14C was discovered by Agarval 60 years ago. The age of the underground waters is the unique benefits to improve numerical models of groundwater flow in large regional aquifers. Traditional underground waters were detected by activity of 14C (PMC).
