INTRODUCTION
Manganese is present in ground water in the divalent state due to the lack of oxygen. In
surface waters, manganese may be in various oxidation states as soluble complexes or as
suspended compounds. Manganese is rarely present in excess of 1 mg/L. It may cause an
objectionable taste or cause staining problems in laundry, but manganese levels normally
encountered in water seldom produce any health hazard.
Manganese is removed from water by various means including chemical precipitation,
pH adjustment, aeration, superchlorination and the use of ion exchange resins.
