Organic-complexed iron, manganese, or both. Summary Iron and manganese are common household water contaminants with no known direct health effects at levels found in water. Their presence may cause staining and offensive tastes and odors. Treatment of these secondary contaminants de pends on the form in which they occur, and the levels of concentration. Iron and manganese removal, bacteria control, water softening and treatment for any other contamination may be separate problems, yet they must be considered together.
Accurate testing is important prior to selection of a treatment system.
