Background

The Alpena CRTC is an active Michigan Air National Guard (ANG) 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. The samples detected PFAS in groundwater at levels above the Lifetime Health Advisory level (LHA) of 70 ppt.

Recent Accomplishments

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.
  • AECOM will create report of water and sediment sampling completed in September 2021.

Military Update

  • The site is currently in the Remedial Investigation phase. The ANG and EGLE have met to discuss the Remedial Investigation work plan. Field work is schedule to start in Spring 2022.

Residential Well Testing/Alternate Water Information

  • DHHS has completed three rounds of drinking water well resampling in the study area.
  • 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.
  • If you live in the designated area for free water testing, please fill out and send the Request for Water Testing for Alpena Area email form.

Residents Please Note

Many residents have inquired about which whole house filters are certified to remove PFOS/PFOA.

* Residential well results are compared to EGLE Part 201 Criteria for 7 PFAS compounds: PFOS (16 ppt), PFOA (8 ppt), PFNA (6 ppt), PFHxS (51 ppt), PFHxA (400,000 ppt), PFBS (420 ppt), and HFPO-DA (370 ppt).
**Surface Water results are compared to EGLE Part 201 Surface Water Cleanup Criteria for PFOS (12 ppt).

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 EGLE "off-base" sampling efforts only.
