The distance between the static water level and the pumping water level is termed the "drawdown". To explain, when a well is pumped, water is drawn from the surrounding aquifer causing the water level around the well to drop. The distance between the original static water level and the new water level is the drawdown. This term is important in determining the well's yield and how much water can be pumped from the well without causing significant harm to the aquifer.
