CONTEXT: Manganese (Mn) is an essential trace element but is neurotoxic at high doses. The likelihood of health impacts from manganese are dependent on factors such as the route of exposure, the chemical form, the age at exposure, and an individual’s nutritional status. Studies have shown that a high content of manganese in drinking water may lead to complications such as intellectual damage as well as a reduced intelligence quotient (IQ) among children who are of school age. It can be present in: • air • food • water • soil and rocks Manganese gets into drinking water sources when water dissolves minerals that contain manganese. In general, manganese is more prevalent and found at higher concentrations in groundwater than surface water. "Does Manganese Inhaled From The Shower Represent A Public Health Threat?." Manganese is a naturally occurring mineral that is present in soils, rocks, and sediment. However, EPA also has established National Secondary Drinking Water Regulations that set non-mandatory water quality standards (secondary maximum contaminant levels or SMCLs) that are used as guidelines to assist water systems with managing drinking water for aesthetic considerations, such as taste, color, and odor.
