Is the statement true: The water level without the pump running is called the static level, the water level with the pump running is called the pumping level, and the difference between the two is called the dropdown?

Is the statement true: The water level without the pump running is called the static level, the water level with the pump running is called the pumping level, and the difference between the two is called the dropdown?

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

Answer: (B)

In pumping tests, the water surface in a well when no water is being drawn is the static level. When the pump is running, the water level lowers to the pumping level. The amount that the water level drops from the static level to the pumping level is called drawdown. The term “dropdown” isn’t used in this context. So the statement is false.
