AWWA-91147 Occurrence of Manganese in Drinking Water and Manganese Control
Occurrence of Manganese in Drinking Water and Manganese Control describes the chemistry and suggested
treatment of manganese in drinking water, with the goals of reducing customer
complaints and improving perceived water quality. Complaints caused by
manganese in drinking water are very common. The problems are aesthetic--water
discoloration (usually black or dark red), clothes and fixture staining, turbid
water, sediments, and, at very high levels, metallic taste. Manganese has no
negative health effects at the levels commonly found in drinking water.
