Abstract: Isotope techniques are effective tools for satisfying critical hydrologic information needs like the origin of groundwater, recharge, residence time, impact of climate change on water resources, interconnections between water bodies, among others. Isotopes provide information that sometimes could not be obtained by other techniques. Stable and radioactive environmental isotopes have now been used for more than four decades to study various aspects of hydrological systems. Stable isotopes are very useful tools which are used extensively in scientific research. Within the field of nutritional studies stable isotopes are used for studying the flow of nutrients through the human body. Since they are safe and non-radioactive they can even be used in infants and pregnant women. In the present study a comprehensive set of measurements of hydrogen and oxygen isotopic composition (2H‰ and 18O‰) taken from a variety of locations for the first time to determine the Local Ground Water Line (LGWL) for groundwater of Agartala. This equation will be useful as a reference point for future studies in this area that use stable isotopes of hydrogen and oxygen to analyze many hydrologic problems.
