Mt. Clemens

There are two sites in the Mt. Clemens area, including the Clinton River and Lake St. Clair which reflect 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.

  • PFOS and PFOA were detected in surface water samples collected on August 31, 2017, from the Clinton River near the city of Mt. Clemens and along the Lake St. Clair shoreline just north of the Selfridge Air National Guard Base in Harrison Charter Township.
  • These samples were collected as part of a targeted monitoring project designed to identify surface waters that could potentially have elevated levels of PFAS.
  • As a follow up to the initial findings, fish and surface water samples were collected from Lake St. Clair north and south of Mt. Clemens in November 2017.  Water samples were collected from the Clinton River at four sites and from the drain near the north perimeter of Selfridge Air National Guard Base to determine the distribution and magnitude of contamination.
  • In early October 2017 the DEQ asked six surface water treatment plants to sample for PFAS.
