An independent drinking water sample was collected from a home on Aspenwood Drive as part of a property transaction. The results showed PFAS levels exceeded criteria for PFOA. These results were shared with the local and state health departments and EGLE. EGLE sampled two homes adjoining the original exceedance, and both drinking water samples contained PFOA above criteria. EGLE expanded the sampling area to include more homes. The highest results were 66 ppt PFOA (compared to 8 ppt). There are several potential sources in the greater area.
Groundwater flow direction is unknown but estimated to be to the west-southwest toward the Thornapple River.
