The former Adak Naval Air Facility occupies approximately 76,800 acres on Adak Island and is part of the Alaska Maritime National Wildlife Refuge. In 1994 the base was added to the National Priority List of contaminated sites, under the terms of the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The air station’s military mission ended on March 31, 1997, and the base was closed that year under the Base Realignment and Closure Act (BRAC).
