What does the coliform group serve as an indicator of?

The coliform group is primarily used as an indicator of water quality, specifically the potential presence of waterborne pathogens. This group of bacteria, which includes E. coli and other related microorganisms, is commonly found in the intestines of warm-blooded animals. Their presence in water suggests that fecal contamination has occurred, which implies that harmful pathogens that can cause diseases might also be present. Monitoring coliform levels allows water operators to assess the safety of drinking water and determine if further testing or treatment is necessary.

Understanding coliform as an indicator organism is crucial for water quality management, as the detection of these bacteria can trigger immediate responses to protect public health. This context is essential in developing appropriate water safety protocols and responding to contamination incidents.
