Current Manganese Exposure Guidelines Deemed Unsafe

Researchers have found a startling link between manganese exposure in children and intellectual impairment. The source of the Manganese exposure? Drinking water. Manganese, a naturally occurring metallic element, has been recognized as dangerously toxic in the workplace and manufacturing since 1837. But, because of its presence in the soil and rock formations, in certain situations manganese will be present in ground water and its health risk needs to be assessed. This study is a first of its kind – to determine if naturally occurring manganese in the drinking water of part of North America and around the world posed any sort of health risk, particularly with children. 362 children were studied and the levels of manganese as well as copper, zinc, iron, arsenic, lead, magnesium and calcium. Tests were performed assessing cognition, motor skills, and behavior. Even when manganese levels were found to be well below current “safe guidelines,” children exposed to higher levels of manganese had a 6 point deficit when compared to children exposed to little or no manganese. Authors of this study said that “few environmental contaminants have shown such a strong correlation with intellectual ability” and have advised that levels of manganese considered to be safe be revised.

What steps can be taken to assure the water our children drink is safe? Some municipalities already filter for manganese. However, additional steps taken at home can greatly reduce or even eliminate exposure to manganese. Systems that filter, reduce, and even remove sediment and mineral content can help you guarantee the safest drinking water for your children and family. Your local Rayne dealer can help you test your drinking water and find a system that works best for your family and budget.
