There’s more work to be done when it comes to sampling fish from local waters for potential PFAS contamination. In an effort to better understand if or how fish have been impacted by PFAS compounds in area surface and groundwater, Tyco caught fish for testing from three privately owned ponds in the site investigation area near their Fire Technology Center. Preliminary test results have been returned and representatives with the company say all those results were inconclusive because they were clouded and impacted by the presence of non-PFAS compounds in the fish tissue, which interfered with the precise measurement of PFAS. In light of these challenges, and in coordination with the Wisconsin DNR, Tyco has hired a second lab to resample the fish tissue and attempt to filter out this interference to more precisely assess the PFOS and PFOA concentrations. That data is expected to be returned by early November.
