What term refers to the level of the water surface in the well when no water is being taken from the aquifer?

• A. Static water level
• B. Dynamic water level
• C. Groundwater table
• D. Water saturation point

Answer: (A)

The term that refers to the level of the water surface in the well when no water is being extracted from the aquifer is known as the static water level. This measurement represents the natural position of groundwater in the well, reflecting the balance of water entering and leaving the aquifer system. When there is no withdrawal, this water level remains stable, indicating the depth at which water can be found under natural conditions.

Understanding static water level is fundamental in water resource management, as it provides critical data for evaluating aquifer health, determining well capacity, and managing extraction rates sustainably. This level is distinct from the dynamic water level, which fluctuates when water is being pumped from the aquifer, often lowering due to drawdown effects. The groundwater table is a broader term that encompasses the upper surface of saturated soil or rock, while the water saturation point pertains to soil moisture levels during saturation and is not directly related to groundwater measurements in wells.
