Answer:
Groundwater depletion and ways for its replenishment
Since the past years, the level of ground water has decreased. Water supply from sources is declining rapidly with each passing year due to an increase in water pollution and population explosion. In order to meet the demand of water, water is being taken out from water bodies such as rivers, ponds etc. hence, the source of ground water is fast depleting as the quantity of groundwater that is withdrawn for human utilization is more than the quantity that is being replaced by rainfall. Small quantities of water penetrates through the ground due to lack of vegetation cover. Another factor that has caused a decline in the availability of ground water is an increase in water pollution.
Measures to replenish ground water are as follows:
Over-exploitation of ground water must be prevented
Water use must be optimized and water demand must be reduced
Promote and encourage rain water harvesting
Prevent deforestation
Promote afforestation, plant more trees
