Answer to Question 1

Ans: D
Feedback:
The route of exposure is how the contaminant enters the body, such as inhalation. The point of exposure is the place where people come in contact with the contaminated medium, which in this case would be the bank of the creek. The source of contamination is used to describe what the contaminants are and where they originate, which in this case would be the chemicals. The environmental medium that the contaminant is in is the creek water.
