Question 2
A water well is contaminated by a nearby pollution source. A consultant suggests drilling a second well to help purify the first well. Evaluate this strategy.
A) This strategy will work to reduce the pollution in the first well by half, since half the pollution will now go to the second well.
B) The strategy will not work because the pattern of flow has been established and the pollution will continue to flow to the first well.
C) The strategy can work if the new well is pumped at a high rate to create a cone of depression deep enough to divert the polluted water.
D) The strategy will only work well if the pollution source has been affected by a well that is drilled into a confined aquifer.
