After the monitor wells are installed, sampled, and the groundwater flow direction refined, the notice of migration documents will be sent out to impacted property owners by the Airport. The monitor wells will be installed after a permit is obtained from the Michigan Department of Transportation, most likely in October 2021. On September 9, 2021, EGLE met with the Airport to discuss the progress of the remedial investigation, the Airport's response to the 2020 releases of PFAS, the schedule for the additional monitor well installation, best management practices to prevent new PFAS releases, and the notice of migration to off-site parties.Additional assessment is needed to determine the risk to the Bay.
PFAS were discovered in a groundwater sample from a residential well located 280 feet from East Grand Traverse Bay (Bay). Connection of the 18 residential drinking water wells to the East Bay Township municipal water system occurred from Mathrough Mathrough a $150,000 grant secured through EGLE and $85,000 from Grand Traverse County. All residential drinking water well owners were notified of their sample results and provided water filters or bottled water from the GTCHD. The other nine residential drinking water wells contained PFAS but all were below criteria. Nine of the 18 residential drinking water wells sampled contained PFAS exceeding the drinking water criteria. EGLE, in coordination with Michigan Department of Health and Human Services (DHHS) and the Grand Traverse County Health Department (GTCHD), sampled the private wells in November 2020. There were 18 residential drinking water wells located within close proximity to the airport. The direction of groundwater flow at the site is generally to the northeast. Groundwater contamination was identified at all five locations and four locations were above applicable cleanup criteria. Soil contamination was identified at three locations. The airport identified and investigated the soil and groundwater at various locations where AFFF was stored or used for testing or areas identified as previous dumps.
The airport received PFAS grant funding from Michigan Department of Transportation (MDOT) to assess areas of historic AFFF storage and use. AFFF is a firefighting foam that is known to contain per-and polyfluoroalkyl substances (PFAS).
