Michigan Dept. of Environment, Great Lakes, and EnergyThis layer displays results for groundwater samples collected by EGLE compared to Michigan Part 201 Residential and Nonresidential Drinking Water Criteria. Coordinates were collected via professional survey or GPS. Samples were collected from December 2017 through present. Results are updated quarterly. This data is used in the North Kent Disposal Area PFAS web map . The pop-up in that map displays: Location ID Sample Date Sample ID Sampling interval (feet below ground surface) Sample Type (Permanent Monitoring Well, Temporary Monitoring Well, VAS) Result in ng//L or ppt for the seven PFAS analytes with Michigan Part 201 Residential and Nonresidential Drinking Water Criteria (DWC) and for Total PFAS, which is sum of all PFAS analyzed.
