Groundwater over exploitation and depletion in groundwater table in many parts of the World posing a serious problem and there is a pressing need to find out the responsible factors. [1][2][3] In addition to the fall in water table, quality of usable groundwater is also deteriorating due to the natural or anthropogenic contaminations. [4][5][6] Some of the factors for depleting groundwater levels and groundwater quality degradation are ever increasing populations; industrial discharges; surface pavements, deforestation etc are affecting recharge zones and recharge sources of groundwater. 7-8 Therefore, identifying, conservation and safeguarding of recharge sources and recharge zones is essential through appropriate measures.Groundwater gets recharged through precipitation, surface water resources, and irrigation return flows. Recharge primarily depends upon its sources, soil characteristics, surface topography, aquifer depth etc. 9 Deep aquifers are potential sources of groundwater as in most of the places shallow aquifers are either dried up or contaminated. 10 Data limitations are there about recharge areas, flows and flow rates of groundwater in deeper aquifers. Groundwater age determination provides useful information to investigate flow and flow rates in deeper aquifers.
