QUESTION $6.$

Two test wells were dug on an industrial site $100m$ apart. The first test well found contaminated groundwater, while the second did not. The difference in groundwater elevation between the two wells is $1\mathrm{.}0m.$ The average aquifer depth is $10m$ and the soil is sandy. Further lateral wells found the plume width to be $50m$ wide. Assuming the plume has almost reached the second well, and the property line is only $20m$ from the second well, calculate the required pumpout rate to capture the plume if a extraction well is drilled at the property line.
