Because these are guidance values, public water systems are not required to meet these values and some do not. 1  If you have an infant who drinks tap water or drinks formula made with tap water, a safe level of manganese in your water is 100 micrograms of manganese per liter of water (Âµg/L)* or less. If you have an infant who never drinks tap water or formula made with tap water, a safe level of manganese in your water is 300 Âµg/L or less. If everyone in your household is more than one year old, a safe level of manganese in your water is 300 Âµg/L or less.
Due to the fact that dissolved manganese oxidizes slower than iron, it is generally more difficult to remove from water. Pure elemental manganese metal is gray tinged with pink, brittle and somewhat harder than iron which it resembles. The pure metal is not found in nature.hen fabrics are washed in manganese-bearing water, dark brown or black stains are formed due to the oxidation of the manganese. The U.S. EPA Secondary Drinking Water Regulations recommend a limit of 0.05 mg/l manganese because of the staining which may be caused.
