What is the minimum pH requirement for Texas drinking water treatment plants?

The minimum pH requirement for Texas drinking water treatment plants is set at 7.0. This standard helps ensure that the water is not too acidic, which could lead to corrosion of pipes and fixtures, potentially releasing harmful contaminants into the water supply. Maintaining a pH of at least 7.0 also helps optimize disinfection processes and improves the overall quality of the drinking water.

In addition to the regulatory aspect, a pH level around neutral (7.0) is generally appropriate for the health of human consumers, as it is close to the natural pH of the human body. This value helps maintain a balance that minimizes adverse effects on taste and the chemical stability of the water.

While lower pH values can pose risks, the specific choice of 7.0 is consistent with national and state recommendations for safe drinking water guidelines. This requirement is part of a broader approach to ensure public health and safety in water treatment and distribution systems.
