Manganese exists in water as a bi-valent ion (Mn2+) and soluble in water, but due to its organoleptic properties, it is considered a pollutant. Manganese (+2) is the most stable oxidation state, which appears as a pale pink colour. When exposed to air, manganese that dissolved in water becomes insoluble and turn brown-red colour [20], [25].
