Iron (Fe) and manganese (Mn) problems affect far more water systems than almost any other water quality concern. The research needed to expand the understanding of the science and technology of these metals is discussed. The oxidation-precipitation and adsorption-oxidation techniques for Fe and Mn control were emphasized since they are the most common approaches used by utilities and because of emerging Fe and Mn problems caused by changes in treatment as a result of the trihalomethane regulations. Sequestration was reviewed because of its increasing use, especially by the small water systems which are frequently afflicted by Mn and Fe problems. It is concluded that there is still much to learn about the chemistry, treatment, and control of iron and manganese and that treatment effectiveness should be improved while treatment costs are reduced. 36 refs.
