Question

A groundwater extraction well is installed in an aquifer (hydraulic conductivity = 2,000 gpd/ft², gradient = 0.01, and aquifer thickness = 50 ft). The design pumping rate is 60 gpm. Delineate the capture zone of this recovery well by specifying the following characteristic distances of the capture zone:

A) the side-stream distance from the well to the envelop of the capture zone at the line of the pumping well,

B) the down-stream distance from the well to stagnation point of the envelop, and

C) the side-stream distance of the envelop far upstream of the pumping well.
