What level of alkalinity in water is considered desirable?

• A. 10 to 20 mg/L
• B. 30 to 100 mg/L
• C. 110 to 150 mg/L
• D. 150 to 200 mg/L

Answer: (B)

The desirable level of alkalinity in water is typically considered to be within the range of 30 to 100 mg/L. Alkalinity is an important water quality parameter as it helps to buffer pH levels, preventing drastic changes that can be harmful to aquatic life and overall water quality. At this range, water can effectively neutralize acids, which is crucial for maintaining a stable environment for organisms and protecting infrastructure from corrosive processes. Alkalinity levels that fall below this range can lead to unstable pH levels, increasing the risk of acidification, while levels that significantly exceed this range might indicate the presence of excessive dissolved minerals, which can also be problematic for both ecosystems and water treatment processes. Thus, maintaining alkalinity within the 30 to 100 mg/L range supports both environmental health and the efficacy of water treatment systems.
