Is the statement true: Drawdown refers to the difference between static water level and pumping water level?

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

Answer: (A)

Drawdown is the decline in water level caused by pumping. It’s measured as the difference between the static water level (the level when no pumping is occurring) and the pumping water level (the level while pumping). For example, if the static level is 50 ft below the surface and pumping lowers it to 70 ft, the drawdown is 20 ft. This concept helps explain how much the well and surrounding aquifer respond to pumping and is a key part of evaluating well performance.
