Mt. Pleasant Roosevelt Refinery

The Roosevelt Refinery reflects known PFAS levels. Based on environmental and health concerns, further review and possible action may be necessary to best protect public health. More details about this location will be made available as soon as possible.

  • The MDEQ has been working with MRP Properties on the Roosevelt Refinery clean-up site since the late 1990s.
  • The DEQ requested that MRP Properties sample the groundwater due to the site being a former refinery because the refinery stored/used fire suppression substances, groundwater samples were taken at 7 locations in August 2017 and analyzed for PFAS.Results are shown in the table below.
  • The DEQ was made aware of PFAS concentrations at the Roosevelt Refinery site in October 2017.
  • The DEQ has requested the company to further define the extent of the PFAS plume on-site.Additional PFAS sampling occurred April 2 and 3, 2018.These results have not been received.
  • The DEQ will continue working with the owner on this site based on the results of this sampling.
  • The DEQ briefed and met with the Saginaw Chippewa Indian Tribe in late 2017.
