Wurtsmith Air Force Base

Wurtsmith Air Force Base is a decommissioned United States Air Force base in Iosco County, Michigan. It operated from 1923 until decommissioned in 1993. 
During the Cold War, it was one of three Strategic Air Command (SAC) bases in Michigan with the B-52 bomber, the others (Kincheloe, Sawyer) were in the Upper Peninsula. The base was named in honor of Major General Paul Wurtsmith, commander of SAC's Eighth Air Force, who was killed when his North American B-25 Mitchell bomber crashed on Cold Mountain near Asheville, North Carolina, on September 13, 1946.
PFAS Contamination.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) became aware of PFAS concentrations in groundwater in March 2010 when EGLE staff performed sampling at a former fire training area on the base. Air Force has completed the PFAS Preliminary Assessment, Site Inspection, and is currently planning the Remedial Investigation under the Comprehensive Environmental Response, Compensation, and Liability Act. Air Force has performed three removal actions and is currently planning two interim remedial actions to address PFAS.
