The average adult diet includes 1 to 10 mg/day of manganese. Infants may require only to mg/day. If dissolved manganese levels are above mg/L, black or gray staining and a bitter metallic taste may result from oxidation of the water. Oxidation and precipitation of manganese will occur when well water mixes with oxygen in the air.
