What is one of the key indicators of water quality?

One of the key indicators of water quality is the pH level, as it measures how acidic or basic the water is. It is crucial because pH affects various chemical and biological processes in water. For instance, a pH level that is too low (acidic) or too high (alkaline) can harm aquatic life and lead to a range of issues, such as reducing the effectiveness of water treatment processes. Maintaining the right pH level ensures that water is safe for human consumption and suitable for the environment.

In the context of water distribution, monitoring pH is essential because it influences corrosion rates in pipes and the solubility of minerals; improper pH levels can lead to issues like pipe deterioration or the leaching of contaminants into the water supply. Therefore, a balanced pH is integral to both the safety and aesthetic quality of drinking water, making it a key indicator in assessing water quality.
