What is a typical indicator of water quality that operators should monitor?

• A. The hardness of the water
• B. The number of minerals present
• C. The presence of coliform bacteria
• D. The color of the water

Answer: (C)

Monitoring the presence of coliform bacteria is crucial for assessing water quality, particularly because it serves as an indicator of potential contamination by pathogenic bacteria and other harmful microorganisms. Coliform bacteria are not usually harmful themselves, but their presence suggests that there might be conditions conducive to more dangerous pathogen introduction into the water supply. This aspect of water quality monitoring helps ensure the safety of drinking water for consumers, as coliforms are often an indication of fecal contamination, which poses significant health risks. Regular testing for coliform bacteria is a regulatory requirement in many jurisdictions, as it helps operators maintain compliance with health standards and protect public health. While aspects such as hardness, mineral content, and color can provide insight into water chemistry and aesthetic quality, they do not directly indicate the presence of harmful pathogens. Therefore, monitoring coliform bacteria stands out as a prioritized indicator for water operators.
