*Groundwater results are compared to the MDEQ Part 201 Criteria of 70 ppt PFOS+PFOA.
*Residential well results are compared to the USEPA Lifetime Health Advisory Level of 70 ppt PFOS+PFOA.
The Camp Grayling environmental staff regularly monitor a number of environmental factors at the camp and airfield to ensure safety, compliance with state and federal regulations, and to proactively detect and remedy potential problems. The most recent proactive measure was to test water samples for PFAS. A few of the samples detected PFOA+PFOS at levels above the United States Environmental Protection Agency (USEPA) Lifetime Health Advisory (LHA).
As of the week of March 12. 2019:
687 private wells have been tested for PFOA/PFOS
684 results are in
452 are non-detects
215 PFOA & PFOS detected (0.56 - 15.6 ppt)
17 samples above MDEQ criteria - PFOA+PFOS 70 ppt
PFOA & PFOS were detected in 232 samples – Concentrations range from 0.56 – 694.2
Grayling Army Airfield PFAS Historical Timeline
Grayling Army Airfield is a 923-acre area owned by the United States Army. The area is just outside the northern boundary of Grayling and is surrounded by residential and commercial properties.
Camp Grayling - Range 30
Groundwater samples were recently collected from 12 monitoring wells at MATES/Range 30. One of those 12 groundwater samples collected at the MATES facility contained a combined concentration of PFOA + PFOS greater than 70 ppt. In an effort to exercise an abundance of caution, we have identified a new area around MATES from which we would like to collect groundwater samples at residences located within that area. The Michigan Department of Military Affairs (DMVA) is currently requesting the permission of residents in this immediate area to collect a sample from their drinking water well. Written permission to sample drinking water must be received and processed before the sample can be collected. Sampling is scheduled to begin the first week of November. We expect analytical results near the end of December.
Residents who live in this area are encouraged to contact Patti Lyman, Michigan Department of Military and Veterans Affairs, at 517-275-0804 ASAP to schedule a time when we can obtain your written permission and collect the groundwater sample.

Many residents have inquired about which whole house filters are certified to remove PFOS/PFOA. At this time, the DEQ is not aware of any whole house filters currently on the market that are certified to remove PFOS/PFOA by the NSF International.
