What is the acceptable pH range for drinking water?

The acceptable pH range for drinking water is between 6.5 to 8.5. This range is crucial because it ensures the water is safe and palatable for consumption. A pH level below 6.5 can lead to water that is acidic, which may cause corrosion of pipes and leach harmful metals such as lead and copper into the water supply. Conversely, a pH level above 8.5 may contribute to a more alkaline water that can taste bitter and could lead to scaling in plumbing systems, affecting water quality over time.

Maintaining this range is essential for not only health considerations but also for the effective functioning of water treatment processes. This pH balance supports the clarity, taste, and overall quality of the drinking water, making it safe for public consumption. The range is set by guidelines from various health organizations, emphasizing its significance in water quality management.
