What is the recommended maximum turbidity level for drinking water?

• A. 5 NTU
• B. 2 NTU
• C. 1 NTU
• D. 0.5 NTU

Answer: (C)

The recommended maximum turbidity level for drinking water is crucial for ensuring the safety and quality of the water supplied to consumers. A turbidity level of 1 NTU (Nephelometric Turbidity Units) is often specified as a target to maintain a balance between treatment effectiveness and water clarity. Above this level, the potential for harmful microorganisms to be present increases, as turbidity can shield pathogens from disinfection processes, making it a key focus in water treatment regulation. Monitoring turbidity is an essential part of water quality management because it can indicate the presence of particles that may harbor bacteria and other pathogens. Keeping turbidity at this level helps ensure that subsequent treatment processes, such as disinfection with chlorine or UV light, are more effective, protecting public health. While lower turbidity levels are desirable and may be targeted in certain high-quality systems or specific circumstances, a maximum of 1 NTU is widely accepted as a standard guideline by health agencies.
