The rivers sampled were the Saginaw, Kawkawlin, Au Sable, Au Gres, Pigeon, Pinconning, and Thunder Bay Rivers. All samples were delivered to Merit Laboratories in East Lansing, Michigan for PFAS analysis. Samples were analyzed for PFOA and PFOS in accordance with Merit Laboratories ASTM 7979-19M Method. PFOA and PFOS concentrations are reported in ppt. The data are included in an excel spreadsheet along with supporting documentation describing the methods used to collect and analyze the samples.
