Manganese Treatment

New Research Highlights Public Health Concerns

Manganese has long been recognized to cause nuisance and aesthetic issues in drinking water. Concerns about the potential health impacts of manganese in drinking water have renewed in response to new research.

The Massachusetts Department of Environmental Protection (MassDEP) has made changes to the requirements for manganese monitoring and public notification. The MassDEP is also encouraging filtration of water with elevated levels of manganese and/or use of alternative drinking water sources.

CEI is well versed in the issues associated with manganese in drinking water and treatment. This webpage provides links to CEI’s literature on manganese and links to other websites with valuable information.

CEI’s Manganese Workshop

Comprehensive Environmental Inc. hosted an informational workshop on manganese in drinking water in April 2013. This workshop provided a review of manganese in drinking water, potential health impacts, recent research, methods of treatment, treatment complications and case studies. MassDEP provided an update on the results of the Central Region Office manganese pilot project and their timeline for recommended increased sampling.

CEI`s Manganese in Groundwater Survey

CEI conducted a survey on manganese in New England groundwater supplies to assess the magnitude of the manganese issue and to provide that information to Public Water Suppliers (PWSs). The results indicate that manganese is prevalent with approximately 76% of responding PWSs having at least one well with manganese greater than the 0.05 mg/L SMCL, and approximately 53% of responding PWSs with manganese greater than the 0.3 mg/L US EPA Health Advisory Level.
