Question

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

Answer 1

Answer:

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.
