Factors responsible for the fall in water levels are:
(1) Population growth,
(2) Industrial and agricultural activities,
(3) Low rainfall,
(4) Deforestation,
(5) Decrease in the area for water absorption etc.
are some of the factors which are some of the factors for lowering the ground level.
1. Population growth.
As the population grows, the demand for construction of buildings, shops, offices, roads, and many other institutions increases. This leads to a reduction in open areas such as farmland and playgrounds. Due to this the rate of absorption of rainwater in the soil decreases. Due to this the groundwater level is constantly drying up.
2. Growing Industries.
Water is being used by all industries. Water is needed in the production of everything. Water used by most industries is extracted from the land.
3. Agriculture.
Many farmers depend on rainfall for the irrigation of crops. Irregular rainfall reduces the availability of water. Therefore farmers have to use groundwater for irrigation. Due to population growth, the use of groundwater for agriculture is increasing day by day. As a result, groundwater levels continue to fall.
4. Poor management of water.
When water is supplied through pipes, leakage occurs in the supply pipes which causes a lot of water loss and therefore causes groundwater levels to fall.
