Quiz which condition could lead to drawdown below the level of existing wells?

Continuous pumping of water causes drawdown. The water table lowers rapidly.

Explanation:

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.
