Guidelines for Drinking-Water Quality
Ensuring the quality of drinking water is essential for public health.

Pathogenic Bacteria : Water should be free from pathogens such as Salmonella, Shigella, Vibrio cholerae, and others. 2. Chemical Safety Nitrates : Should not exceed 50 mg/L. High levels of nitrates can cause methemoglobinemia or "blue baby syndrome" in infants. Lead : Should not exceed 0.01 mg/L.
