I share these articles to show the complexity of satisfactorily removing manganese from drinking water; both at the source and in the finished drinking water to homes. Very expensive, very complex, lots of chemistry involved, and many ancillary unintended by products can result.
Manganese and iron have always been in the Village's drinking water. In the past the village employed water softeners in an ion exchange, replacing manganese with sodium. These softeners have not been utilized since the early 1970's and ultimately were dismantled and scraped in the 1980's. The exact reason's for non continued use, were in part do to change in water chemistry, non maintenance of equipment, and poor training and lack of knowledge by operators.
For the village to continue to embark on a path of attempting to treat and manage the reservoirs and treatment facilities is one that is predestined for failure. A long history has shown that millions have already been invested in this attempt, with worse not better results.
This is throwing good money after bad. These source waters, including the wells should not be utilized for primary drinking water purposes.
Instead the should be disbanded or in the case of the wells used for secondary or emergency purposes. The primary source needs to be the treated water provided by MVWA, which already has invested hundreds of millions into their treatment facility, and do not experience in their service to 18 municipalities the water quality issues of the Village of Ilion.

Abstract
Manganese (Mn) in drinking water can cause aesthetic and operational problems. Mn removal is necessary and often has major implications for treatment train design. This review provides an introduction to Mn occurrence and summarizes historic and recent research on removal mechanisms practiced in drinking water treatment. Manganese is removed by physical, chemical, and biological processes or by a combination of these methods. Although physical and chemical removal processes have been studied for decades, knowledge gaps still exist. The discovery of undesirable by-products when certain oxidants are used in treatment has impacted physical–chemical Mn removal methods. Understanding of the microorganisms present in systems that practice biological Mn removal has increased in the last decade as molecular methods have become more sophisticated, resulting in increasing use of biofiltration for Mn removal. The choice of Mn removal method is very much impacted by overall water chemistry and co-contaminants and must be integrated into the overall water treatment facility design and operation.....continue to site

Manganese is a type of metal that is commonly found in the well water around the world. It occurs naturally in the soil. It is washed into the drinking water from the rain plus the surface water that seeps into the ground.
Indeed, the manganese in the water can be a nuisance. It produces a metallic aftertaste on the water, it stains the clothes, it clogs the valve and produces a crusty sheen on the surface of the water.
Due to the stains, bad taste, and general nuisance of manganese in the water, the federal government created a standard for it. It was clearly discussed in the Safe Drinking Water Act of 1974.
The good news is, there are various water treatment options that can enable the water to become safe for drinking. As such, you don’t have to live your life drinking contaminated water.
Thus, this article aims to introduce ways in the removal of manganese in the water. Also, this would tackle the drinking water standards and the initiatives of the authorities to protect its citizen.... continue to site
