However, a small percentage of the population may be affected if they suffer from an excess of iron in the body (hemochromatosis). ... This process of iron and manganese removal
Are there federal standards for manganese in drinking water? Manganese levels are not regulated in public water supplies. However, the US Environmental Protection Agency has established an aesthetic water quality standard of 50 μg/L. Manganese levels below 50 μg/L should prevent the staining of bathroom fixtures and laundry.
Manganese Removal by physical-chemical way As for iron, the origin of manganese, in water, is at the same time natural (dissolution of the reduced form Mn 2+ )
Drinking water with a level of manganese above the MDH guidance level can be harmful for your health, but taking a bath or a shower in it is not. Manganese in your water can stain your laundry, cause scaling on your plumbing, and make your water look, smell, or

While both iron and manganese are unlikely to cause health problems, there are several reasons to remove them from a water supply. Excessive iron and manganese in a water system can promote the growth of different types of bacteria. A disproportionate amount of iron and manganese can also lend an unpleasant taste and color to drinking water.
