Iron and Manganese in Household Water
Iron and manganese are naturally occurring minerals found in certain rocks and soils that can be dissolved by groundwater. Corroding iron or galvanized steel pipes may also be a source of iron in household water. Typically, neither iron nor manganese presents a health risk to humans when present in a household water supply; however, a portion of the population suffering from hemochromatosis (excess iron in the body) may be especially sensitive to iron in drinking water. Iron and manganese are primarily associated with nuisance problems such as staining of clothes and plumbing fixtures or objectionable taste. Iron and manganese are similar chemically and therefore produce similar problems. Iron and manganese are usually either dissolved (in solution) in water or found in particulate form.
