Coliform Bacteria: Threat or Indicator?

Coliform bacteria are a type of microorganism commonly found in the environment and in our daily lives. They are a key indicator of water quality, providing valuable information about potential contamination. However, coliform bacteria themselves can pose a threat to human health if present in high concentrations or if consumed without treatment. Therefore, it is important to maintain proper water treatment and sanitation measures to ensure the safety of our drinking water sources. By understanding the role of coliform bacteria, we can better protect ourselves and our environment from potential health risks.
