Question

Write critical notes Groundwater depletion and ways for its replenishment

Solution

Ground water depletion and ways for its replenishment: - The level of ground water has decreased in the recent years. The source of water supply is rapidly diminishing each year because of an increase in the population and water pollution. To meet the demand of water, water is withdrawn from water bodies such as ponds, rivers etc. As a result, the source of ground water is depleting. This is because the amount of groundwater being drawn for human use is more than the amount replaced by rainfall. Lack of vegetation cover also results in very small amounts of water seeping through the ground. An increase in water pollution is another factor that has reduced the availability of ground water.

Measures for replenishing ground water:-

(i) Preventing over-exploitation of ground water

(ii) Optimizing water use and reducing water demand

(iii) Rain water harvesting

(iv) Preventing deforestation and plantation of more trees
