The factors responsible for the depletion of the water table are as follows:
(i) Increasing population :
The higher the number of individuals, the higher the need for daily use, which will lead to a decrease in groundwater.
(ii) Increasing industries :
Industries need a lot of water for manufacturing purposes. This reduces the water table.
(iii) Agricultural activities
In a way, an increasing number of agricultural fields will help the population but more the fields will lead to more irrigation systems.
