||The U.S. Environmental Protection Agency (EPA) has prepared this Health Effects Support Document to assist in determining whether to establish a National Primary Drinking Water Regulation (NPDWR) for manganese. At high doses by inhalation, manganese is very toxic, as seen by occupational exposure in miners. On the other hand, manganese is essential for normal physiological function of animals and humans. The Food and Nutrition Board of the National Academy of Science (NAS) sets an adequate intake for manganese at 2.3 mg/day for men and 1.8 mg/day for women, and an upper limit for daily intake at 11 mg for adults (IOM, 2002). Manganese has a low aesthetic threshold in water. Based on staining and taste, EPA has set a secondary level for manganese at 0.05 mg/L which is below the level that may present a health concern. Available data suggest that regulation of manganese in public water does not present a meaningful basis for health risk reduction. EPA will present a determination and further analysis in the Federal Register Notice covering the Contaminant Candidate List proposals.
