The presence of fecal coliform in a water sample indicates a risk of disease. True or False?

The correct answer is that the presence of fecal coliform in a water sample indeed indicates a risk of disease, making the statement true. Fecal coliform bacteria are a group of bacteria that are commonly used as an indicator of water contamination by fecal matter, which can contain a variety of pathogens harmful to human health. Their detection suggests that other harmful microorganisms, such as viruses and parasites, may also be present, posing a potential risk for waterborne diseases.

Understanding this is crucial, especially for maintaining water quality and public health safety. Monitoring water sources for fecal coliform levels is a standard practice in water quality management, as it helps to assess the likelihood of contamination and guides decisions regarding water treatment and safety. Thus, stating that the presence of fecal coliform indicates a risk of disease is accurate and underscores the importance of regular monitoring and testing of water supplies to protect public health.
