What is the typical pH range for drinking water?

The typical pH range for drinking water is between 6.5 to 8.5. This range is essential for ensuring the safety and palatability of drinking water. Water that is too acidic (below a pH of 6.5) can leach metals such as lead and copper from pipes, posing health risks to consumers. Conversely, water with a pH higher than 8.5 can give it a slippery feel, which might indicate the presence of certain minerals, and can also reduce the effectiveness of disinfectants such as chlorine. It also may promote scale formation in pipes and appliances, leading to operational challenges in water distribution systems. Therefore, maintaining a pH within this specific range is crucial for both public health and the infrastructure of water delivery systems.
