Contamination score

Higher = more contaminated vs. other cities.

Adak is a documented EPA Superfund site: the former Naval Air Station was added to the National Priorities List in 1994 after groundwater contamination with trichloroethylene (TCE) and other petroleum, metal, and pesticide contaminants was found across 181 evaluated sites. Tap water in some older housing areas (Sandy Cove and Eagle Bay) has also raised lead-in-plumbing concerns. Cleanup and monitoring remain ongoing, with some areas still above levels safe for unrestricted use.
