Abstract
Groundwater Age Determination- Insight into Groundwater Recharge, Flow Systems and Contamination Studies
Highlights
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 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] 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]
