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.

Drinking water
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.
AECOM will continue to monitor new residential sampling requests and call residents to set up sampling dates and times as directed by EGLE. All residential well testing reflected on this report has been conducted by EGLE.
Anticipated activities
ANG plans to conduct additional remedial investigation activities in Fall 2023.
