Find out the reasons for lowering of water table of underground water?

Answer 1

the reasons are :

1)over population-increase in population has caused an increase in the amount of water used in agricultural fields, industries and domestic uses

2)sewage- the improper channelising of sewage water also results in an increase in polluted water that cannot be used anymore and so it is also like depletion

Answer 2

In open fields some rain water makes its way through the ground to the water table. Other water drains across the fields to streams. Some of that water drains down to the water table. Many cities no longer permit rain water to percolate into the water table but divert it to storm sewers. That water then goes either to rivers downstream or out to the ocean.

Answer 3

1. excessive use due to increasing population.

2. increase in industrialisation.

Answer 4

Over much of the earth, the demand for water exceeds the sustainable yield of aquifers and rivers. Water tables are dropping steadily in some areas due to this.

Answer 5

it is because most of the land is covered with concrete in cities which does not allow seepage of water resulting in a low water table

Answer 6

The lowering of the water table of underground water is likely to occur during a long period of dry weather, especially in summer.
