If a body of water has high turbidity levels, what can most likely be concluded?

• A. It is unsafe to drink.
• B. It has a low pH.
• C. It is too hot to drink.
• D. It contains a lot of chemicals.

Answer: (A)

Turbidity is about how cloudy water is due to suspended particles like dirt, silt, and organic material. When water is highly turbid, those particles can carry microbes and provide surfaces for them to cling to, and they can shield microorganisms from disinfectants. That combination makes the water less reliably safe to drink until it’s properly treated. The cloudiness doesn’t by itself tell you about acidity (pH), temperature, or dissolved chemical levels, which can vary independently of turbidity. So the most reasonable conclusion is that the water is unsafe to drink until it’s filtered and disinfected.
