Manganese in Drinking Water: A New Concern States throughout the region are taking a tough stance on the levels of manganese in local drinking water. Manganese is prevalent in New England groundwater which often makes its way into our drinking supplies at concentrations exceeding the Secondary Maximum Contaminant Level. This can cause excessive amounts of oxidized materials in water mains. Additionally, the latest research from the EPA indicates health concerns with high levels of Manganese are also prevalent. The Massachusetts Office of Research and Standards and the United States Environmental Protection Agency have indicated that long-term exposure to manganese exceeding 0.3 mg/L can have negative health effects on infants less than six months of age. The Massachusetts Department of Environmental Protection has included a more stringent age cutoff of one year in Drinking Water Standards and Guidelines. Additionally, the Connecticut Department of Public Health, following the World Health Organization guidance level to protect against manganese toxicity, has set a drinking water Action Level for manganese of 0.5 mg/L. It is imperative that communities take action to reduce manganese in drinking water supplies to safe levels. Tata & Howard appreciates that mitigating manganese levels in drinking water requires a well-thought out and executed balance between maximizing quality while minimizing costs. Many options are available, including polyphosphate addition, replacement wells, filtration, and revised operational procedures.
