1.ABSTRACT

“ When the last tree is cut and the last fish killed, the last river poisoned, then you will see that you can't eat money. - John May Ground Water depletion is one of the most important environmental threats faced by humanity. Ground water reserves in various forms are depleting at alarming rates all over the world and is matter of huge concern, especially in India who is the largest user of ground water in the world. Groundwater is a vital resource, with a large fraction of the population re-lying on the resource directly or lying indirectly for livelihoods. It accounts for about 50–80% of domestic water use and 45–50% of irrigation in 50 50% the country. This heavy reliance on groundwater for both domestic water and irrigation purposes is now n approaching its limit as an increasing number of aquifers reach unsustainable levels after decades of exploitation. This term paper tries to understand the various causes that led to the present status of the depletion and the existing measures taken to control it and explores the possibilities for sustainable use of ground water in future.

2.OBJECTIVES OF THE TERM PAPER: OBJECTIVES     Investigate the causes of the ground water depletion Understand the effects of depletion through case studies. Analyse the existing measures taken to curb it Explore future action methodologies.

3. REVIEW OF LITERATURE

3.1 INTRODUCTION Ground water lies beneath the earth’s surface, filling pore spaces between the grains of sediment or within the voids of sedimentary rock. Groundwater may also fill fractures in rock. Water becomes groundwater when precipitation infiltrates the geosphere. The Water Table The zone below ground where the pore spaces are filled with ground water is called the saturated zone. Above the saturated zone, where the pore spaces are not filled with ground water, is the unsaturated zone. The water table marks the boundary between the saturated and...
