A note about Manganese:

Manganese is naturally present in the reservoirs that serve Asheville and Buncombe County. Manganese is an essential nutrient; it is recommended to receive 2 to 5 mg/day for adults and 0.3 to 0.6 mg/day for infants. A US EPA reviewed study has shown that manganese levels below 0.17 mg/L in drinking water showed no-adverse-health-effect-level (NOAEL). During normal operation, the manganese level of City of Asheville water stays well below our Secondary Maximum Contaminant Level (SMCL) of 0.05 mg/L. During discolored water events, manganese levels could temporarily exceed the 0.17 mg/L NOAEL. The US EPA Lifetime Health Advisory (HA) for manganese is 0.3 mg/L (for a 22 pound child consuming 1 Liter of water per day, the 1 day & 10 day Health Advisory is 1.0 mg/L). However, it is advised that for infants younger than 6 months, the lifetime HA of 0.3 mg/L be used even for an acute exposure of 10 days.
