A contaminant plume in the aquifer threatens the drinking water well serving the whole village. The confined aquifer is 20 m thick. It has a hydraulic conductivity of 1.0104m/s, a storage coefficient of 3.7105, and a regional hydraulic gradient of 0.003 . The contaminant plume is 300m wide at its widest point. The maximum allowable pumping rate based on the allowable drawdown is 0.006m3/s. a. Write the equation of the capture zone curve for single extraction well and describe the equation? (2M) b. Sketch a map showing the drinking water well, extraction well, capture zone curve and the approximate plume. (3M) c. Locate a single extraction well, so that the stagnation point is 100m from the drinking water well and so that the capture zone encompasses the plume. (10M)
