WAFB began operations in 1923, under the name of Camp Skeel, and was officially named the Wurtsmith Air Force Base in 1953. The base is located in Oscoda, Iosco County, Michigan. WAFB closed in 1993 and is gradually being turned over to the Oscoda Airport Authority for reuse as an industrial park and airfield (EPA 2012). The 5,221-acre site is bounded by Van Etten Lake to the north and east, Oscoda and Au Sable Townships to the east and south, the Huron National Forest (including wetlands associated with the Au Sable River) to the south, and the Au Sable State Forest to the north and west. Lake Huron is less than one mile east of the site (ATSDR 2001).
