This research study describes the chemistry and suggested treatment of manganese in drinking water, with the goals of reducing customer complaints and improving perceived water quality. The problems are aesthetic-water discoloration (usually black or dark red), clothing and fixture staining, turbid water sediments, and, at very high levels, metallic taste.

Manganese in drinking water is an aesthetic problem, characterized by so-called "black water", laundry spotting, and similar issues. The control of manganese in a water distribution system relates more to reducing consumer complaints than to protecting health. However, consumers often judge drinking water based on its appearance, odor, and color at the tap even if it is safe to consume. The control of manganese is complicated by its complex chemistry. The objective of this project was first to evaluate the occurrence, chemistry, and treatment methods associated with manganese (Mn) in ground and surface waters. Building upon these findings, a further goal was to study problems associated with manganese in water distribution systems and measure Mn in specific distribution systems. Another objective was to estimate achievable, cost-effective target levels for manganese below the current drinking water advisory standard of 0.05 mg/L. The research team conducted a comprehensive literature review. This review dealt with the regulatory history, health effects, chemistry, and technology associated with Mn. A survey was used to determine the industry’s knowledge base as well as obtaining certain occurrence data. This data was a focused set. Certain utilities participated in distribution system sample analysis. These samples were taken along the length of the distribution system, including the near, middle, and far ends. The concentration of Mn was determined and speciation was conducted via filtration. Case studies were performed to test the limits of certain Mn control technology. Finally, a cost model was proposed to help quantify the cost of increased Mn control as compared to the benefit realized by consumer.

This project summarizes current knowledge about manganese chemistry, treatment control strategies, manganese occurrence, distribution system issues, and long- and short-term health effects. The report overviews chemical oxidation, adsorption, biological filtration, and ion exchange techniques for removing manganese from drinking water. In addition to the literature review, a January 2001 workshop was convened to identify future manganese research needs. These research proposals are detailed in a prioritized, multiyear research agenda that describes a series of research projects and funding requirements. An extensive bibliography is provided, but no index. Annotation copyrighted by Book News, Inc., Portland, OR.

This Best Practice Guide on the Control of Iron and Manganese in Water Supply is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. Iron and manganese are often found in soft upland water sources associated with natural organic matter and are also commonly found in the groundwater abstracted from confined and unconfined aquifers. The presence of iron and manganese in water is one of the most frequent reasons for customers’ complaint due to aesthetic issues (yellow, brown and black or stains on laundry and plumbing fixtures). These two metals can be removed fairly readily by physico-chemical treatment. The municipal treatment systems deployed derive benefit from their larger scale, particularly in relation to control, but the processes used are less suitable for the numerous small supplies that are the most common water supplies throughout Europe, especially in rural areas. One important source of iron in drinking water is from old corroded cast-iron water mains, historically the material used most commonly in supply networks. Replacement and refurbishment is very expensive and the major challenge is how best to prioritize available expenditure. The purpose for this Best Practice Guide on the Control of Iron and Manganese in Water Supply is to give readers the broad view of a problem based on state-of-the-art compilation of the range of scientific, engineering, regulatory and operational issues concerned with the control of iron and manganese in drinking water. The Guide is of interest to water utility practitioners, health agencies and policy makers, as well as students on civil engineering and environmental engineering courses.

Pre-engineered water treatment plants are becoming available and being used for production of potable water at public water systems. Many applications being proposed are for small systems having relatively clean surface water sources which are now being required to provide filtration under the federal Safe Drinking Water Act. This book looks at the control of iron and manganese in drinking water.

Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.
