WHAT IS MANGANESE?
Manganese is a mineral that, in very small amounts, is essential for proper functioning of the human body. It is a trace mineral present in the human body in small quantities, primarily in the bones, liver, kidneys and pancreas. Manganese is important in connective tissues, in the formation of bones and blood-clotting factors. It is also involved in fat and carbohydrate metabolism, calcium absorption and blood sugar regulation. In addition, manganese is important for brain and nerve function. As you will read below, it can also present potential health problems at higher levels.
Evidence of manganese in water can often be seen inside dishwashers as a black residue as well as in toilets and shower stalls. It can also give water a brown color and can be found in particulate and dissolved forms. Water filtration solutions can address either form.
There are two forms of manganese in the environment: Inorganic and organic compounds. Inorganic compounds are used in the production of steel, batteries, ceramics and dietary supplements. These compounds are also generated as combustion products from motor vehicles and coal-burning industrial plants. Organic manganese compounds are used in some pesticides, fertilizers and in a gasoline additive called Methylcyclopentadienyl manganese tricarbonyl (MMT). Manganese compounds can also be present as dust particles in the air and dissolved in groundwater or drinking water
WATER SOFTENER FOR MANGANESE, IRON & HARDNESS MINERALS
A water softener is effective in removing dissolved forms of manganese, iron and hardness minerals. To remove particulate manganese or iron, a cartridge filter with proper micron rating will be effective. Selecting the appropriate micron rating and style of filter can be determined by a water treatment professional based on water test results and other symptoms.
Manganese toxicity potential
According to the U.S. Environmental Protection Agency (EPA), the World Health Organization (WHO) and the Agency for Toxic Substances and Disease Registry (ATSDR), manganese at very high levels can pose a neurotoxic risk. Exposure to high concentrations over the course of several years has been associated with toxicity to the nervous system, producing a syndrome that resembles Parkinsonism. This type of effect may be more likely to occur in the elderly.
Higher risks for children
Children are considered to be particularly susceptible to possible effects of high levels of manganese exposure because they absorb more and excrete less manganese than adults. This adds up to a greater potential for exposure in the very young. Since manganese’s effects on the developing nervous system have not been adequately studied, it is especially prudent for pregnant women and young children to have drinking water that is below the EPA action level. ATSDR reports several studies that showed decreased ability in neuro-behavioral performance testing and in several educational parameters in children exposed to high level of manganese in drinking water and diet for several years.

OTHER AFFECTS OF MANGANESE, IRON, AND HARD WATER
Some of the affects of these contaminants include corrosion and scaling inside pipes, major staining throughout the home’s showers, bathtubs, and sinks and destruction of hot water heaters way ahead of their useful life. Without water softening, hard water scale can also build-up inside hot water heaters insulating the temperature sensor inside the tank causing them to work much harder to bring the temperature up to the set level. This will reduce the useful life of your hot water heater and require early replacement. For those using their well water for outside lawn irrigation, iron and manganese can cause major staining of outside walkways, house siding and anyplace the water touches.
