Importance and Essence

Shows the overall microbiological quality and sanitary condition of the water
A high CFU count indicates the level of microbial contamination, the potential presence of pathogens, and the risk to human health

Where Used

Occupational health and safety assessments (drinking water quality)
Water control in industrial facilities (food industry, technological processes)
Environmental studies (assessment of water body status, wastewater analysis)
