Liners Found NonDetect for PFAS

Geoprobe® submitted samples of our clear PVC soil liners, including the lay flat liners used for sonic soil sampling, to Jennifer Field, Ph.D., at Oregon State University and her research team. Field’s team analyzed the Geoprobe® soil liners for 52 PFAS compounds, including PFOS and PFOA. The PVC liners tested nondetect for all 52 compounds. The research concluded that field sampling materials are an unlikely source of contamination for Perfluoroalkyl and Polyfluoroalkyl substances in field samples.
