What is the maximum allowable turbidity level in drinking water after treatment?

The maximum allowable turbidity level in drinking water after treatment is set at 0.3 NTU (Nephelometric Turbidity Units). This standard is crucial because turbidity can indicate the presence of pollutants or microorganisms, which may pose health risks. The standard of 0.3 NTU is established by regulatory agencies to ensure that treated drinking water is safe for consumption and free from contaminants. This level reflects a balance between public health protection and the practicalities of water treatment processes, ensuring clarity in drinking water while safeguarding against potential health hazards linked to turbidity.
