Safe drinking water is a fundamental right, and standardization plays a crucial role in maintaining its quality. Bacteriophages are microbiological indicators that allow the assessment of potential fecal contamination of water, providing essential data for the prevention of health risks.

The implementation of international standards ensures a precise and verified methodology for the detection and enumeration of these bacterial viruses, thus contributing to increasing the safety of drinking water. These standards also support the authorities responsible for water quality control, strengthening the protection of consumers against possible microbiological hazards.
