This map shows contours of the water table,the location of four factories (labeled A,B,C,and D),and contaminated and uncontaminated wells.Which way will the contamination flow?
A)north and northeast,up the contours
B)south and southwest,down the contours
C)northwest and southeast,parallel to the contours
D)impossible to tell because the movement of contamination is independent of groundwater

Quizplus · Accepted Answer

Contamination will flow downhill along the direction of the water table, which is indicated by the contour lines. The contour lines slope towards the south and southwest, indicating that groundwater flows in that direction. Therefore, the contamination is likely to flow towards the south and southwest, contaminating the wells in its path.
