Manganese MCL refers to the maximum contaminant level for which element?

Maximum contaminant level is the highest amount of a contaminant that may be present in drinking water while still protecting public health. When the term manganese MCL is used, it designates the regulatory limit specifically for manganese, the element manganese. This limit is set to control taste, staining, and potential health effects. The other elements listed—iron, lead, and copper—have their own separate MCLs, but the phrase manganese MCL refers to manganese itself.
