What is the maximum contaminant level (MCL) for turbidity in drinking water?

The maximum contaminant level (MCL) for turbidity in drinking water is set at 1.0 NTU (Nephelometric Turbidity Units). This standard is important because turbidity can indicate the presence of pathogens and other harmful contaminants in water. Water treatment facilities use this measure to ensure water clarity and safety for consumers. Turbidity levels above the established MCL can point to inadequately treated water, which could pose health risks to the community. Consequently, maintaining turbidity at or below 1.0 NTU is a critical aspect of safe drinking water standards, as it helps minimize the likelihood of microbial contamination.
