Question: 1 / 400

What does the term coliform bacteria refer to?

A group of bacteria used as an indicator for fecal contamination in water

Coliform bacteria are a group of bacteria commonly used as an indicator of fecal contamination in water systems. Their presence in water suggests that pathogens capable of causing disease may also be present, making them a critical indicator for assessing water quality and safety. These bacteria are typically found in the intestines of warm-blooded animals, which is why they are significant in evaluating the hygienic quality of drinking water and the potential risks associated with recreational water activities.

This understanding is crucial for sewage treatment workers, as monitoring for coliform bacteria helps ensure that sewage treatment processes are effective and that treated wastewater is safe for discharge into the environment or for reuse. By identifying coliform levels, treatment facilities can implement necessary measures to mitigate contamination risks and protect public health.
