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.
Railroad tracks, for example, are made with steel that contains as much as 1.2% manganese. Manganese is also used to give glass an amethyst color and is responsible for the color of amethyst gemstones. Manganese dioxide (MnO 2), the most common compound of manganese, makes up about 0.14% of the Earth's crust. It is used in dry cell batteries to prevent the formation of hydrogen, to remove the green color in glass that is caused by the presence of iron contaminants, and as a drying agent in black paints.
