What is the ideal pH range for potable water?

The ideal pH range for potable water is between 6.5 and 8.5. This range is considered optimal for several reasons. First, it minimizes the potential for corrosion in water distribution systems and plumbing, which can leach metals such as lead and copper into the drinking water supply. Secondly, maintaining a pH within this range ensures that the water is palatable and does not have a noticeable taste or odor, making it more acceptable for consumption.

Additionally, the specified pH range supports the effectiveness of disinfection processes and helps in the removal of contaminants, thus contributing to overall water quality and safety. Extreme pH levels, either too low or too high, can lead to adverse health effects and other issues such as scaling or accelerated corrosion of pipes and fixtures. Hence, water utilities strive to adjust and monitor the pH of drinking water within this ideal range to protect public health and maintain infrastructure integrity.
