Coordinates were collected via GPS. Samples were collected from November 2020 through July 2022. This data is used in the North Kent Disposal Area PFAS web map . The custom pop-up displays: Location ID Sample Date Sample ID Sample Type (Wolverine Pore Water Sample) Result in ng/L or ppt for seven PFAS analytes: PFHxS, PFOA, PFOS, PFBS, PFNA, PFHxA, and HFPO-DA and for Total PFAS, which is sum of all PFAS analyzed.
