Quizplus · Accepted Answer

The contour lines show that the water table is flowing from north to south, and the factory is located to the northwest of the contaminated area. Therefore, drilling wells to intercept the contamination would be most effective to the southeast of the factory, where the contaminated groundwater is flowing towards. Drilling wells to the north or southwest would not necessarily intercept the contaminated plume, and drilling wells right next to the factory could potentially cause further contamination.
