The Lansing Hangar is a facility located on the Capital Region International Airport property in Lansing Michigan. Results from a Preliminary Assessment performed by the Michigan Army National Guard (MIARNG) in 2020 identified two potential releases of PFAS in the area of this facility. The C-12 Hangar and Extinguisher Training Areas were both identified as potential release areas. Use of PFAS-containing aqueous film-forming foam (AFFF) were released during a training exercise. Both potential PFAS release areas were grouped into one investigation area, which was investigated during the site inspection in July 2021.

Groundwater contours indicate the general flow of groundwater is to the southeast.

EGLE conducted residential well sampling at 11 homes located near the Capital Region International Airport and did not identify any wells impacted by PFAS. Routine monitoring of municipal wells located in the area also did not identify impacts by PFAS.

During 2023, a remedial investigation will be the next phase of work conducted at the Lansing Hangar. MIARNG will continue working with local and state officials to facilitate progress towards remediation at the Lansing Hangar. The remedial investigation phase can take anywhere from 3 to 5 years to complete, followed by a feasibility study, proposed plan, and a record of decision, all of which will include EGLE and the department of health as stakeholders. The proposed plan will include a public comment phase.
