    Alpena Heat Map detecting PFOA and PFOSBackground

    The Alpena CRTC is an active Michigan Air National Guard training facility and is located seven miles west of the city of Alpena. As part of the United States Air Force (USAF) comprehensive approach to protect human health, several areas of the Alpena CRTC were tested for PFAS. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) was made aware of this site when the Department of Military and Veterans Affairs notified EGLE on October 2, 2017, of groundwater samples collected on-base on May 16, 2017, that detected PFAS in groundwater at levels above the Lifetime Health Advisory level (LHA) of 70 ppt.

    Recent Accomplishments

    • On April 10, 2020, the Department of Health and Human Services (DHHS) sent a press release detailing January 2020 resampling efforts of residential wells surrounding Alpena CRTC. Results were consistent with EGLE’s initial sampling efforts. Results letters were sent to residences that participated in the resampling. Read the official press release.

    Next Steps

    • AECOM will continue to monitor new residential sampling requests and call residents to set up sampling dates and times as directed by EGLE.

    Military Update

    • Nothing to report.

    Residential Well Testing/Alternate Water Information

    • Households with detections of PFAS have been provided point of use filters and replacement cartridges by District Health Department #4.
    • All residential well testing reflected on this report has been conducted by EGLE.
    • For additional information on residential well testing and results, visit the Frequently Asked Questions.
    • EGLE has sampled all municipal water supplies for PFAS. View the results for the city of Alpena.

    Upcoming Community Engagement

    • None scheduled at this time.
  • Sampling: PFOS and PFOA Only

    Sampling notes

    • Other PFAS analytes were detected in samples. There are no federal or state standards for these analytes.
    • All sample counts and activities reflect “off-base” sampling efforts only.
  • Historical Timeline

    The CRTC is an active Michigan Air National Guard training facility and is located seven miles west of the city of Alpena. It was built in 1940 and is a year-round training facility; one of four CRTCs in the United States. The Alpena CRTC environmental staff regularly monitor a number of environmental factors at the facility to ensure safety, compliance with state and federal regulations, and to proactively detect and remedy potential problems. As part of the USAF’s comprehensive approach to protect human health, several areas of the Alpena CRTC were tested for PFAS. EGLE was made aware of this site when the Department of Military and Veterans Affairs (DMVA) notified EGLE on October 2, 2017, of groundwater samples collected on-base on May 16, 2017, that detected PFAS at levels above the LHA of 70 ppt.
