Why does the EPA have a “secondary standard” for manganese in drinking water? Drinking water manganese (WMn) is a potential threat to children's health due to its associations with a wide range of outcomes including cognitive, behavioral and neuropsychological effects. Manganese (Mn) is an element found in air, food, soil, consumer products and drinking water. As the chemical occurs in drinking-water at concentrations much lower than the health-based value, the presence of malathion in drinking-water under usual conditions is unlikely to represent a hazard to human health. Is manganese in drinking water regulated?
