Following factors are responsible for depletion of water table:
• There is more demand of water due to increasing population. Which lead to increasing demand of water for various human activities.
• Deforestation has removed a large portion of forest cover. This has disturbed the natural process of recharging the groundwater.
Demand for water has increased and the recharging of the ground water has reduced. The mismatch between demand and supply is mainly responsible for depletion of water table.
Drip irrigation and sprinklers system can be used in the garden to minimize the use of water. Watering to plants should be done to minimise loss of water by evaporation. https://www.tiwariacademy.com/ncert-solutions/class-7/science/chapter-16/

Ten tube-wells are too much for a lane of fifty houses, this can lead people to mindlessly exploit the groundwater. This can lead to depletion of the water table in the long run. https://www.tiwariacademy.com/ncert-solutions/class-7/science/chapter-16/

The rainwater and water from other sources such as rivers and ponds seeps through the soil and fills the empty spaces and cracks deep below the ground. The process of seeping of water into the ground is called infiltration. By the process of infiltration, groundwater gets recharged. https://www.tiwaRead more
