<u>Answer:</u>
Continuous pumping of water causes drawdown. The water table lowers rapidly.
<u>Explanation:</u>
- Water table is the level below which the ground is saturated with water.
- During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
- But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
- To prevent this, the groundwater should be recharged and over drawing should be avoided.
