Answer 2

Answer:

Some of the points can be briefly listed as follows:

1. Heavy agricultural activities on a patch of land

2. Pumping of underground water from borewells, tubewells and using them for irrigation.

3. Lack of rain in that area: the ground water is often used as a substitute for rain water, and when rain doesn't occur, the water table falls.

4. Industrial activities that consume too much ground water, like pulp and paper mills, sugar mills and refineries etc.

5. Increasing pollution also disturbs the ground water level. Increasing population, phenomena like acid rain, etc. also cause problems in the purity and water table.
