What is the normal pH range of potable water?

The normal pH range of potable water is widely accepted to be around pH 7.0, which indicates neutrality. Water at this pH level is neither acidic nor basic, making it ideal for drinking. It is essential for potable water to maintain this neutral pH to ensure safety and palatability for consumers and to prevent corrosion in plumbing systems. Maintaining a pH level close to 7.0 helps to safeguard both the quality of the water and the infrastructure involved in its delivery.

In contrast, variations outside of this neutral range can affect water quality and taste; for instance, acidic water (pH lower than 7) may lead to corrosion of pipes, and alkaline water (pH higher than 7) could result in scaling and mineral buildup. Thus, a pH level of 7.0 is considered the optimal standard for potable water.
