Dissolved Oxygen: Water with a low dissolved oxygen level lends itself best to manganese reduction by ion exchange. Mostly present as manganous ions, manganese can be removed with a water softener or oxidizing filter. Manganese can also cause discolouration and an unpleasant taste in drinking water. Manganese (Mn) is an element found in air, food, soil, consumer products and drinking water. Manganese is found naturally in groundwater, but levels can be increased by human activities like steel production and mining. Yet manganese can also present a problem if found in well water in quantities greater than 0.05 mg/L.In that case, manganese can give the water an unsightly brown appearance, while also often lending the water an unappealingly bitter taste. Water with . Though manganese is not found as often in a water supply as iron, it is just as annoying, causing black and brown stains and turbidity. People who consume water containing high levels of manganese (in some cases as high as 28 mg/L) have also developed manganese toxicity [4,42]. Currently known cases of manganese poisoning have occurred at elevated levels much higher than levels found in most natural water. Manganese is routinely contained in groundwater, drinking water and soil at low levels. While a small amount of manganese is essential for human health, new Health Canada research has shown drinking water with too much manganese can be a risk to health. The most common treatment method for manganese is a Water Softener. Manganese is a common element found in minerals, rocks, and soil. This is true simply because high oxygen levels promote precipitation of manganese to a physical form that is hard for the softener to handle. See the following document for more detailed information about Manganese in Household Water. Potassium permanganate is used in water purification, manganese dioxide in the manufacture of dry batteries and fireworks, manganese chloride in animal feed, and manganese sulfate as a fertilizer. Higher concentrations prompt the use of chemical oxidation. 500 ppm TDS works best for manganese removal by a water softener. Because manganese is a natural component of the environment, you are always exposed to low levels of it in water, air, soil, and food. Manganese can turn the water a brown or rust color, cause staining of faucets, sinks, or laundry, and make the water have an off off-taste or odor. The aim of this study was to analyse the published literature on the potential effects of manganese exposure from drinking water on school-age children, with emphasis on cognitive, and neurodevelopment and behavioural effects. water of 0.005 mg/kg/day has been calculated by EPA from a human no-observed-adverse-effect level (NOAEL) of 0.005 mg/kg/day; the NOAEL was determined from an epidemiological study of human populations exposed for a lifetime to manganese concentrations in drinking water ranging from 3.6–2300 μg/L (Kondakis et al. However, manganese toxicity has occurred in people working in such occupations as welding and mining who were exposed to high amounts of manganese from chronic inhalation of manganese dust [1,41]. Manganese effects occur mainly in the respiratory tract and in the brains. "The manganese, as it settles from car exhaust onto streets and highways, may enter the water supply, increasing manganese levels in the water we drink and bathe in," said Spangler.
