Ken Tesh Water Distribution Operator Exam 3 Practice

A pH of 5 indicates that the water is acidic, which can lead to corrosive potential. The pH scale ranges from 0 to 14, where a value of 7 is considered neutral. Values below 7 indicate acidity, while values above 7 indicate basic (alkaline) conditions.

At a pH of 5, the water is significantly more acidic than neutral, which can contribute to corrosion in piping systems and infrastructure. This level of acidity can lead to the leaching of metals from pipes and fixtures, posing a risk not only to the integrity of the water distribution system but also to public health if harmful substances enter the drinking water supply.

In contrast, neutrality, alkalinity, and basic conditions all relate to higher pH values. Neutrality is specifically at pH 7, alkalinity reflects the ability of water to neutralize acids (which would require a higher pH), and basic conditions indicate a pH greater than 7. Thus, the indication of corrosion potential at a pH of 5 is the most accurate and relevant interpretation.
