Aside from iron, the mineral that is most often found in excess in water is manganese. In some cases, particularly in swampy areas where oxygen levels in groundwater are low, manganese is more easily dissolved and can be present in well water at significantly higher levels. These sediments are responsible for the staining properties of water containing high concentrations of iron and manganese. Removing manganese with a filter requires a higher pH than iron. Usually it is not easily dissolved from these sources and its concentration in well water is low. Yet, in general, there are higher concentrations of the mineral in standing water than groundwater. Manganese can also cause discolouration and an unpleasant taste in drinking water. Manganese is a widely occurring mineral substance with a key role to play in human nutrition.
