This map shows contours of the water table,the location of four factories (labeled A,B,C,and D ),and contaminated (x)and uncontaminated wells (-).Which factory contaminated the groundwater?

A)Factory A 
B)Factory B 
C)Factory C 
D)Factory D

Quizplus · Accepted Answer

The contaminated well is located closest to Factory C, and the contours of the water table show that the groundwater is flowing from Factory C towards the well. Additionally, Factory C is located downhill from the contaminated well, which increases the likelihood of contamination flowing towards the well. Factories A, B, and D are not located close enough to the contaminated well and their respective contours do not show any indication of groundwater flow towards the well.
