What pH range is considered acceptable for pool water?

• A. 6.0 to 6.5
• B. 7.0 to 7.5
• C. 7.2 to 7.8
• D. 8.0 to 8.5

Answer: (C)

The acceptable pH range for pool water is 7.2 to 7.8 because this range promotes both swimmer comfort and optimal chlorine effectiveness. Maintaining a pH within this range ensures that the water is neither too acidic nor too alkaline. When the pH is too low, it can lead to skin and eye irritation for swimmers and can also corrode pool equipment. Conversely, if the pH is too high, it can result in decreased chlorine efficiency, leading to an increased risk of algae growth and unsanitary conditions. A pH of 7.2 to 7.8 strikes a balance that helps to keep the water both safe and pleasant for users, supporting proper sanitation and equipment maintenance.
