I gave my students this multiple choice question: If a body of water has high turbidity levels, what can most likely be concluded?

Only one answer is correct among these 4 choices:
- It has a low pH.
- It is unsafe to drink.
- It is too hot to drink.
- It contains a lot of chemicals.

Could you tell me which one is correct?
