Iron and Manganese in Private Water Systems

18/10/2019· Manganese often results in a dense black stain or solid. For these reasons, it is recommended that drinking water have no more than 0.3 mg/L (or 0.3 parts per million) of iron and less than 0.05 mg/L of manganese. The U.S. Environmental Protection Agency has also set a Health Advisory for manganese of 0.3 mg/L.
