No. Manganese is not currently regulated as a national primary drinking water standard which means there is no enforceable limit for manganese in drinking water. However, EPA is in the process of determining whether to regulate manganese due to updated health effects information and additional occurrence data.

Nearly all manganese ores are beneficiated near the mine sites to improve the manganese grade before further processing. Most also are smelted to form the alloys ferromanganese and silicomanganese. It is these alloys, rather than manganese ore itself, which are used in most metallurgical applications.
