Question

When water is pumped from a well, drawdown occurs. What is a true statement regarding drawdown?

a. Drawdown is the rise of water in a well.
b. Drawdown is the decrease in water level around the well.
c. Drawdown does not affect the water table.
d. Drawdown is caused by excessive rainfall.

Answer 1

Drawdown is the decrease in water level around the well. It can have significant effects on the water table, such as saltwater intrusion, subsidence, and sinkholes.

Step-by-step explanation:

Drawdown is the decrease in water level around the well. When water is pumped from a well, it creates a localized drop in the water table known as a cone of depression. This drop in water level is referred to as drawdown. It is important to note that drawdown can have significant effects on the water table and can cause saltwater intrusion, subsidence, and sinkholes.
