Manganese is not present in natural waters, but it is found in various salts and minerals, frequently associated with iron compounds.
Manganese salts are used as fertilizer additives, in ferroalloys (in steel manufacture), in non-ferrous alloys as it improves their corrosion resistance and hardness.
Manganese is not considered to be toxic to man and aquatic life and it is present as a trace nutrient, both in food and water. Nonetheless manganese has been limited in drinking water as it causes tenacious stains to laundry and alters taste.
Manganese is commonly found in domestic wastewater and industrial effluents.
