Water: A Precious Resource
Explain how groundwater is recharged.
The rainwater and water from other sources, such as rivers and ponds, seep through the soil and fill the empty spaces and cracks deep below the ground. The process of seeping water into the ground is called infiltration. The groundwater thus gets recharged by this process.
There are ten tube wells in a lane of fifty houses. What could be the long-term impact on the water table?
If ten tube wells in a lane of fifty houses are situated, the groundwater will get used for domestic purposes. This results in the depletion of the groundwater level, and the water table goes down.
You have been asked to maintain a garden. How will you minimise the use of water?
We can reduce the usage of water for gardening by adopting the drip irrigation method. In this method, water will reach the roots of the plant drop by drop, which will reduce the wastage of water.
Explain the factors responsible for the depletion of the water table.
The factors responsible for the depletion of the water table are as follows:
Increase in population: Increase in population leads to increased demand for water for domestic and drinking purposes. This reduces the water table.
Industrialisation: Industries need a lot of water for manufacturing purposes. This reduces the water table.
Agriculture: Agriculture requires a lot of water for growing crops; this results in the depletion of the water table.
