Affiliated Researchers conducted vibracore sediment sampling on the Au Sable River, Michigan to test for the presence of PFAS. Affiliated Researchers trained team of Scientists and Technicians used our shallow-water vibracore vessel, underwater vibracore system, and RTK-GPS survey equipment to collect vibracore sediment core-samples at specified locations on the river. Affiliated Researchers has collected thousands of vibracore sediment samples at hundreds of project locations throughout the US.
