Kalamazoo/Battle Creek International Airport (Airport), located at 5235 Portage Road in Portage, is a certified commercial service airport that has Class B Aqueous Film Forming Foam (AFFF) to meet federal aviation requirements. AFFF is a firefighting foam that is known to contain PFAS compounds.
The Airport received grant funding from Michigan Department of Transportation (MDOT) to assess areas of historic AFFF storage and use. The Airport identified and investigated the soil and groundwater at six locations where AFFF was stored, used for testing, or deployed as a result of a plane crash.
The direction of groundwater flow at the site is generally to the north, northwest. There are approximately 30 residential drinking water, irrigation, or Type III wells located within close proximity to the Airport. EGLE, in coordination with the Department of Health and Human Services (DHHS) and the Kalamazoo County Health and Community Services Department (KCHCSD), began sampling the private wells in July 2020. As a result, there was one residential drinking water well with PFAS exceeding criteria. All well owners have been notified of their sample results and the home with the criteria exceedance has been provided a water filter from the local health department. The location where PFAS was detected above criteria does not appear to be related to any of the investigation areas identified by the Airport.
The City of Kalamazoo has two municipal well fields with associated pumping stations to the north of the Airport. The City has and continues to sample those wells for PFAS. There have been low level detections of multiple PFAS compounds, and the City has not utilized those wells since mid-2019.
There are six drainage ditches along the east side of the Airport site. All drainage flows to Davis Creek located to the east of the site near Kilgore Road.
