Question

2) You want to design a pumping system with a capture zone that exactly contains the plume. The regional head gradient is 0.05 m/m, and the aquifer hydraulic conductivity is 10^-5 m/s. If you install the pumping system down-gradient of the plume. what pumping rate would you need to just capture the plume in gallons/minute?

3)With that pumping rate, and assuming that the plume concentrations stays at equilibrium. how many pore volumes would you need to pump to recover all the contaminant?

4) With your pumping rate, how long would this take?

5) if the plume is irrefular in shape and you neep to pump an area with radius of 200m t contain the plume, what pumping rate would you need?

6) In this irregular case how long would it take to recover all contaminant?
