Depletion of water table
Underground water is replenished by seepage of rainwater.
Depletion if water table is caused due to many reasons such as
- Increase in population decreases the open areas required for water seepage due to construction of houses, offices, roads and also the construction works need high amount of water.
Fig. Increasing population cause construction of more houses, offices, roads.
- Industries need huge amount of water for production purposes and increasing industries cause depletion of water table.
- Less rainfall also cause less seepage of rain water.
- For agricultural activities farmers need huge amount of ground water for irrigating their crops and thus cause depletion of ground water.
