EGLE Site Lead:
Wurtsmith Air Force Base served primarily as a combat crew and bomber training base throughout its 70-year history. Since its establishment in 1923, Wurtsmith played an important role in World War II, Vietnam and the Persian Gulf War, hosting the 134th Army Air Force Base Fighter Unit and 379th Bombardment Wing. Wurtsmith was officially closed on June 30, 1993. Most of the acreage (4,354 of 4,628 acres) of the former base has been transferred for reuse.
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 Civil Engineering Center (Air Force) is the lead cleanup agency. 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.

Residential Well Testing/Alternate Water Information
- MDHHS is offering drinking water well retesting to Oscoda-area residents whose wells were previously tested for PFAS or who were offered drinking water filters, or both. There is no charge for the testing. MDHHS has contacted these residents by letter and by phone to schedule water collection appointments. Seasonal residents who are away for the winter can schedule an appointment at a later date. The goal of the repeat testing is to determine if PFAS is in residential wells; if so, the amount of PFAS; and whether the amount is increasing, decreasing, or remaining the same over time. MDHHS will be retesting these drinking water wells in coordination and District Health Department No. 2. Residents who have questions about this PFAS testing effort or who would like to schedule an appointment can call the MDHHS Drinking Water Hotline at 844-934-1315.
- More information on residential well sampling is included in the Oscoda Area page.
