What is the acceptable pH range for drinking water?

The acceptable pH range for drinking water is 6.5 to 8.5 because this range balances acidity and alkalinity, which is important for both safety and palatability. pH levels below 6.5 can indicate acidity that might lead to leaching of metals from plumbing, while levels above 8.5 could result in the water being too alkaline, which might interfere with water treatment methods and the effectiveness of disinfection. Drinking water within this pH range also helps to ensure good taste and minimizes corrosion of plumbing materials, contributing to safer drinking water and protecting public health.
