Answer to Question 1

Ans: B, C, D, E
Feedback:
Environmental media include groundwater, surface water (lakes, ponds, and rivers), air, surface soil, subsurface soil, sediment, and biota (plants and animals). The environmental medium that the contaminant is in helps determine who is exposed and how they are exposed. Mercury is an example of a contaminant, or source of contamination.
