What is the maximum turbidity level required for filtered water in at least 95% of monthly samples?

The maximum turbidity level required for filtered water in at least 95% of monthly samples is set at 0.3 turbidity units. This standard is important to ensure the quality of drinking water and reflects the ability of the filtration process to remove particulate matter, which can carry pathogens and compromise water safety.

Maintaining turbidity at or below this level helps to prevent aesthetic issues in the water, supports disinfection processes, and complies with regulatory requirements aimed at protecting public health. Filtration systems are designed to achieve high removal standards, and regularly checking turbidity levels is essential for operators to confirm that the treatment processes are functioning effectively. The choice of 0.3 turbidity units represents a balance between operational feasibility and the necessary safety measures to ensure that the water supplied is clean and safe for consumption.
