5. A capture well is pumping at a rate of 152,000 ft³/day. The confined aquifer has a thickness of 102 ft and a hydraulic conductivity of 118 ft/day. The head in a monitoring well 1,490 feet up-gradient of the capture well is 135 feet above a datum and the head in a second monitoring 1,020 feet down gradient of the capture well is 129 feet above the same datum. a. What is the maximum width of the capture zone? b. What is the distance from the well to the stagnation point?
