Fort Wainwright - Main Post (AK) Water Quality

Fort Wainwright - Main Post is a large public water system in EPA region 10 that provides tap water for the 99703 zip codes. It has 8 facilities where the water supply was tested for 75 chemical contaminants that impact tap water quality and human health.

The maximum reported level of HAA5 (five regulated haloacetic acids) was 34.9 µg/L. The maximum reported level of Manganese was 672 µg/L. Some (6 of 8 or 75%) of the latest water samples showed levels of Manganese that were at or above unsafe concentration levels. There were 2 contamintants found in the Fort Wainwright - Main Post water supply at levels that were above the minimum reporting level. 1 of the contaminants were above the reference level, which means they may pose a risk to human health.
