GRAYLING, MI — The Michigan National Guard will test residential drinking wells near Camp Grayling this summer after groundwater testing turned up a plume of toxic fluorocarbons possibly migrating toward the Au Sable River.
Roughly 100 homes with private wells located west and south of the Grayling Army Airfield are at risk for contamination from perfluoroalkyl substances (PFASs), also known as perfluorinated chemicals (PFCs), detected at concentrations above the federal health advisory level in five monitoring wells along the airfield perimeter.
Sampling rounds in October, December and March have turned up successively higher concentrations of perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS), emerging contaminants of concern which are tied to thyroid, kidney, liver, reproductive and other health problems.
March testing found PFOS at 740-ppt and total PFAS at 801-ppt at a well along W. North Down River Road across from the city police and fire departments, which is roughly 10 times above the Environmental Protection Agency’s dual 70-ppt health advisory level for PFOS & PFOA.
What if you know National Guards that have had to go to camp for thrier training. How has or will it affect our troops????
