The Secondary Maximum Contaminant Levels (SMCL) are used to regulate contaminants like iron and manganese in drinking water. These guidelines primarily focus on aesthetic qualities of water, such as taste, odor, and color, rather than on health-based standards. Iron and manganese, while not considered primary health concerns at common levels, can cause staining in laundry and fixtures, as well as an unpleasant taste when concentrations exceed certain thresholds.

Setting SMCLs for these metals helps water treatment facilities manage the quality of water that is supplied to consumers to maintain an acceptable experience. This regulation encourages the treatment of water to avoid issues related to aesthetic quality, ensuring that it meets the preferences of consumers while also addressing potential nuisance problems caused by higher levels of iron and manganese in water supplies.
