The World Health Organization (WHO) guideline of 50 ppm and the US maximum contaminant level (MCL) of 45 ppm for nitrate in drinking water are established for the protection of infants from methemoglobinemia. The WHO guideline for nitrite is 3 ppm and the MCL 1 ppm. The water must also be microbiologically safe.
