Grayling Township municipal water extension map

The Grayling Township municipal water extension project, as detailed in this map, is intended to provide safe drinking water to PFAS-affected residences in the Grayling Army Airfield and Camp Grayling – Lake Margrethe MPART investigation areas. EGLE has given all residential and commercial well owners in the investigation areas the opportunity to be sampled since PFAS was found at the Grayling Army Airfield in 2017.

Drinking water

Update: January 23, 2025 - EGLE to provide additional $26.5M for Grayling Township municipal water extension projects

MDHHS will be re-testing residential drinking water wells near the Grayling Army Airfield, Lake Margrethe, and Maneuver and Training Equipment Site (MATES) at Range 30 for PFAS. The testing will help MDHHS determine if there are changes to levels of PFAS in residents’ drinking water. There is no charge for the testing.  Households with detections of PFAS have been provided point of use filters and replacement cartridges by District Health Department #10. All residential well testing reflected on this report has been conducted by EGLE.

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

ARNG is also conducting residential sampling in select areas. Residents in these areas will be sent Army Corp of Engineers letters asking for access.  ARNG needs to verify DHHS and EGLE data to provide remedy to residents in the area.

Municipal water has been chosen by stakeholders to be the best final solution for providing safe drinking water to residents. Municipal water extensions are planned for the Grayling Army Airfield area starting in summer 2025. Grayling Township has been awarded $26.5 million in grant funds by EGLE to start the project in Fall 2024. ARNG will also be providing financial support starting in Fall 2024.

 

Anticipated activities

EGLE continues to review incoming data, continue to monitor new residential sampling requests and call residents to set up sampling dates and times. EGLE will continue sampling of monitoring wells in the Grayling area and will continue to review ARNG reports and workplans in a timely manner to facilitate ongoing work.
