North State Road Area of Interest (Ionia, Ionia County)

EGLE Site Lead: Aaron Assmann, AssmannA@Michigan.gov or 616-430-4275. Webpage last updated September 8, 2021.

Background

PFAS sampling results for the community water supply wells at Evergreen Mobile Home Community (MHC) showed low-level detections of two PFAS compounds. A review of potential PFAS sources in the area was inconclusive, but the potential for aqueous film forming foam (AFFF) use in response to a local vehicle, house and/or tire fires was suggested.

Municipal water supply is unavailable in the area, and local residences and businesses are on drinking water wells. The area with the detections is in a wellhead protection area.  Regional groundwater flow is to the southeast.

Recent Accomplishments

  • In August 2021, EGLE collected samples at 13 drinking water wells.
  • In August and September 2021, EGLE worked with MDHHS and the local health department to communicate results to property owners and rental tenants.  Alternate drinking water is being provided to locations where any PFAS has been detected. 

Next Steps

  • EGLE will perform a geologic review to aid in additional sample collection and potential source identification.
  • EGLE will work with MDHHS and the local health department to coordinate sampling of additional nearby drinking water wells.

Residential Well/Alternate Water

  • Municipal water is not available in the area. Initial residential well sampling occurred in August 2021 and included 13 drinking water wells. Five homes had PFAS concentrations that exceed EGLE drinking water clean-up criteria. Three homes had PFAS concentrations below EGLE drinking water clean-up criteria and five homes were non-detect for all PFAS analyzed.

Upcoming Community Engagement

  • None scheduled at this time.
