Question

what are the various reasons for decreasing levels of ground water in states of India

Answer 1

DEAR Student,
SOLUTION:
There are many contributing factors for depletion of underground water table

1. Over exploitation of underground water. It is obvious that the vast number of constructions going everywhere, use underground water then and after.

2. Lack of replenishment of underground water. New style constructions including roads and buildings totally cover the surface with no chance of water seeping down. Hence the underground water table does not get replenished.

3. Cutting of trees. Trees used to hold water and release it to ground. the tree and vegetation cover is depleting the underground water table also depletes.

4. Lack of vast open spaces. here used to be many large expanses vast open uninhabited spaces which helped to collect rainwater and hold it down as underground water table. As more and more are come under construction these open spaces vanish contributing to underground water scarcity.

5. Insufficient rains. Insufficient rains contribute for non replenishment of underground water. Watever little rains fall on the surface and flow down or get evaporated soon. The rains do not wet the soil and enable water to seep deep down.
