The factors responsible for the depletion of the water table are as follows:
(i) Increased population: As our population increases, correspondingly the demand for water also increased.
(ii) Increasing industries: The number of industries is on the rise ever since the human population began multiplying exponentially. These industries need water for various processes.
(iii) Lack of water conservation techniques: Rain is the main source of water for both surface and underground water bodies. Upon proper conservation, the groundwater can be increased. This has not yet been achieved due to lack of implementation of such water conservative techniques.
(iv) Agricultural activities: Our country depends vastly on its agricultural roots and the land that is used for cultivation has increased. Hence, water consumption has also increased. Groundwater is exploited as there is an irregularity in the rainfall.This results in the depletion of groundwater.
(v) Urbanisation: Large scale construction requires a lot of water and puts great stress on the water table.
