Quizplus · Accepted Answer

To intercept the contamination, it is best to drill wells southeast of the factory. This is because the contours of the water table are sloping in a southeasterly direction, which indicates that groundwater flows in that direction. Drilling wells in this area will intercept the contaminated groundwater before it flows further southeastward. Drilling wells in other areas, such as right next to the factory or north/southwest of the factory, may not be as effective in intercepting the contamination due to the direction of groundwater flow.
