Manganese in New England Water

High Manganese in Water

Manganese, an essential mineral, is present in many water sources. While it's generally harmless at low levels, high concentrations of manganese can lead to a variety issues.


High manganese levels in water can stem from natural sources such as rocks and soil. Human activities like mining and industrial processes can also contribute to elevated levels. This mineral may give your water a slightly brown hue and an unpleasant taste or odor. Furthermore, it can stain fixtures, laundry, and appliances with a brownish-black tint, making your water aesthetically unappealing and potentially damaging to your belongings.


While manganese is generally safe at low levels, high concentrations can pose health risks, especially for children. Long-term exposure to elevated levels of manganese has been linked to neurological issues. Additionally, manganese can cause scaling and other plumbing problems, reducing the lifespan of your plumbing system. It can also react with chlorine bleach, intensifying staining issues.


Staining, unpleasant taste, and potential health risks are all concerns associated with elevated manganese levels. Implementing a suitable water treatment system or exploring alternative water sources can help mitigate these problems, ensuring your water is clean, safe, and pleasant to use.

Remedies for High Manganese Levels

Several methods can help reduce manganese levels in water. One common approach is using a water treatment system, such as a filter or water softener, to remove excess manganese. Another solution is to consider alternative water sources, like wells or springs, that have lower manganese levels.


Water softeners are effective at reducing manganese levels, as they can replace manganese ions with sodium ions. Oxidation and filtration is another method where the manganese is converted into a solid form, which is then filtered out.
