Background

Eaton Rapids Municipal Landfill is located southwest of Eaton Rapids next to Hogsback Road and a half mile northeast of East Spicerville Highway.  The city of Eaton Rapids owned and operated the landfill within a 40-acre parcel in the 1960's through the late 1970's.  After the landfill was closed, it was regraded and capped with clay in 1980.  EGLE asked the city of Eaton Rapids to conduct PFAS sampling because of the landfill site history and the location of nearby residential wells. In 2019, a shallow groundwater monitoring well (MW-9) was sampled and had a combined level of PFOS + PFOA at 112 ppt which is above the groundwater cleanup criteria of 70 ppt.  Three other shallow groundwater monitoring wells had PFOS + PFOA at concentrations ranging from 32 ppt to 65 ppt.     

In late April 2020 the city of Eaton Rapids expanded PFAS sampling to 14 monitoring wells and four surface water sample locations. Concentrations of PFOS + PFAS in one monitoring well increased from 112 ppt to 141 ppt.  Three other monitoring wells were above the cleanup criteria.   The city of Eaton Rapids uses a consulting firm to collect annual groundwater samples from monitoring wells and nearby surface water bodies.

Recent Accomplishments

  • In late April 2020, the city of Eaton Rapids sampled fourteen (14) monitoring wells and collected four (4) surface water samples for PFAS analysis.   EGLE requested that the city of Eaton Rapids provide the PFAS analytical results shortly after the data was verified.
  • On June 9, 2020, EGLE provided notice to Barry-Eaton District Health Department (BEDHD) of the April 2020 PFAS analytical results.
  • EGLE, BEDHD and Michigan Department of Human Health and Services (DHHS) held an on-line meeting on June 17, 2020 to identify the most at-risk residential wells to be sampled for PFAS in the early Summer of 2020.   Eight residential wells were selected for initial sampling.   The Draft Site-Specific Public Health Action Plan was discussed.

Next Steps

  • By June 26, 2020 EGLE will request that the city of Eaton Rapids voluntarily sample eight (8) residential wells for PFAS.  
  • In early summer, 2020 BEDHD will contact residents for permission to sample eight (8) residential wells.   The residential wells will be sampled utilizing established COVID-19 protocols.  Residential well PFAS sampling is planned to start in July 2020.

Residential Well Testing/Alternate Water Information

  • The city of Eaton Rapids Municipal Water Supply is over two miles northeast of the landfill and not expected to be at risk for PFAS contamination from the landfill. 
  • In late June or early July, an on-line meeting will be held between EGLE, MPART, BEDHD, DHHS, and local officials to discuss the residential well sampling and public health action plan.
