Michigan Dept. of Environment, Great Lakes, and EnergyThis layer displays a heat map for residential well samples compared to Michigan Part 201 Residential and Nonresidential Drinking Water Criteria. Original location data source is Kent County parcel points (center point of parcel boundaries), supplemented with GPS data. Well samples were collected from April 2017 through present. If more than one sample was collected from a residential well location, including influent whole house filter monitoring samples, the maximum results for each PFAS analyte across samples is maintained in this layer. Results are updated quarterly. This data is used in the North Kent Disposal Area PFAS web map . The pop-up in that map displays: Address Total number of samples Highest/maximum result in ng/L or ppt for 7 PFAS analytes with Michigan Part 201 Residential and Nonresidential Drinking Water Criteria (DWC) and for Total PFAS, which is sum of all PFAS analyzed. The fields found in this dataset are: Field Name Description Address Street Address Sample_Count Total count of samples collected at well, excluding whole house filter mid-point and effluent samples, if applicable Type Sample Type: Irrigation or Residential Well Sample T_TotalPFAS Highest Total PFAS result across samples in text format T_PFOA Highest PFOA result across samples in text format T_PFOS Highest PFOS result across samples in text format T_PFNA Highest PFNA result across samples in text format T_PFHxS Highest PFHxS result across samples in text format T_PFHxA Highest PFHxA result across samples in text format T_PFBS Highest PFBS result across samples in text format T_HFPODA Highest HFPO-DA result across samples in text format AreaBoundary Used to mark and query sample locations within North Kent Study Area All7PFAS Non-Detect (No Detections of PFNA, PFOA, PFHxA, PFOS, PFHxS, PFBS, or HFPO-DA), Detection, no exceed (One or more PFAS Analytes Detected Below Michigan Part 201 Drinking Water Criteria), or Exceeds (One or more PFAS Analytes Detected Above Michigan Part 201 Drinking Water Criteria) You can find more information about the North Kent Study Area by visiting the House Street Disposal Area webpage or the Rockford Tannery webpage on the Michigan PFAS Action Response Team (MPART) website .
