註釋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. - taken from executive summary.
