How do aeration and taste/odor control relate to finished water quality?

• A. Aeration adding minerals to improve taste.
• B. Aeration heats water to improve odor.
• C. Aeration helps remove volatile compounds that cause taste and odor problems, improving consumer acceptance.
• D. Aeration changes the color of water.

Answer: (C)

Removing volatile compounds that cause taste and odor problems is what aeration achieves at the finished-water stage. By bringing water into contact with air, aeration strips these volatile substances out of the water. As a result, the water’s taste and odor improve, which helps ensure consumer acceptance of the finished product. Aeration does not add minerals, does not heat the water, and is not primarily about changing color, so those statements don’t fit.
