2017 Investigation Timeline

2017 Investigation Timeline

  • On January 24, 2017, a concerned citizens group brought the former House Street disposal location to EGLE’s attention on January 24, 2017. In response to these concerns, EGLE requested that Wolverine sample residential wells.
  • In May 2017, EGLE received results from Wolverine from the requested residential well sampling. Levels of PFOA and PFOS were detected over the USEPA Lifetime Health Advisory of 70 ppt PFOA and PFOS individually or combined.
  • In August 2017, Wolverine began its on-site groundwater investigation on the House Street Dump Site, which has expanded off-site in order to define the full extent of the PFAS contamination. This investigation is still ongoing, and more work is needed by Wolverine to fully define and monitor the plume long term.
  • In Fall/Winter 2017, per a request by the school district, the water at several Rockford Public Schools was tested. The results were non-detect.
  • Beginning in the Winter of 2017, Wolverine has been conducting off-site groundwater environmental investigations in the Wolven/Jewell source area (located north of 10 Mile and west of Wolven Ave).
