Description: This layer displays a heat map for groundwater samples collected by Wolverine World Wide, Inc. compared to Michigan Part 201 Residential and Nonresidential Drinking Water Criteria. Coordinates were collected via professional survey or GPS. Samples were collected from August 2017 through present. Results are updated quarterly. This data is used in the North Kent Disposal Area PFAS web map.
