Why our ground water is depleted? Explain.

Answer»

1. Excessive pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater.(i)Increasing populationAs a result of increasing population, all the facilities such as houses, shops, roads,offices, pavements, etc. increase to fulfil the increasing demands. This, in turn,decreases the open area for seepage of water into the ground.(ii)Increasing industriesMost of the stages of manufacturing processes in industries require water. If the numberof industries increases, then the water required by them will also increase. Therefore,increase of industries contributes to the depletion of water table.(iii)Agricultural activitiesIndia is an agricultural country and agriculture is impossible without water. The water foragriculture is mainly utilised from ground water, rain water and canal water. As there isno rainfall in many places, agriculture cannot be entirely depended on rain water. Also,canal water is available in a few places only. Therefore, ground water is the main sourceof water for agricultural activities and this causes depletion of water table
