What is the typical range for pH in a well-balanced water supply?

• A. 5.0 to 6.5
• B. 6.0 to 7.5
• C. 6.5 to 8.5
• D. 7.0 to 9.0

Answer: (C)

The typical pH range for a well-balanced water supply is 6.5 to 8.5. This range is important because it indicates water that is neither too acidic nor too alkaline, ensuring safety for human consumption and the proper function of water systems. Water with a pH level within this range also supports the health of aquatic life and helps prevent the corrosion of pipes and fixtures, which can lead to leaching of metals into the drinking water. A pH below 6.5 may indicate acidic conditions, which can cause corrosion and potentially harmful effects on both infrastructure and health. Conversely, a pH above 8.5 can lead to excessive alkalinity, which can affect water taste and also hinder disinfection processes. Therefore, maintaining a pH within the range of 6.5 to 8.5 is crucial for a balanced and healthy water supply.
