What is the acceptable pH range for potable water?

The acceptable pH range for potable water is 6.5 to 8.5. This range is important because it helps ensure the water is safe for human consumption and minimizes the risk of corrosion in plumbing systems, which could lead to leaching of metals into the water.

A pH lower than 6.5 may indicate acidity, which can erode pipes and carry contaminants from the system into the water supply. On the other hand, a pH higher than 8.5 can lead to scaling and affect water taste, as well as interfere with the effectiveness of disinfectants used in water treatment processes. Thus, the specified range balances the need for safe drinking water while also protecting the infrastructure involved in water delivery.
