Is manganese safe in drinking water?

Manganese is classified as a Secondary Drinking Water Contaminant and, because of this, has no regulated level. It does have a secondary standard of 0.05 mg/L but this is not enforced. Secondary Drinking Water Contaminants are classified as contaminants that cause aesthetic issues but are not generally seen as a risk to one's health.
