Is the statement true: Drawdown is the difference between static level and pumping level?

Is the statement true: Drawdown is the difference between static level and pumping level?

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Drawdown is the drop in the water surface that occurs when a well is pumped. It is found by taking the static water level (the undisturbed level when nothing is drawing water) and subtracting the pumping level (the lower level reached while pumping). The difference between those two levels is the drawdown, so the statement is true. If you don’t pump, the pumping level and static level are the same, and there’s no drawdown. The other options don’t fit because this concept is a standard way to quantify how much the water level falls during pumping.
