Title:Initial state-wide survey results from the Wisconsin Department of Natural Resources (WDNR) per- and poly-fluorinated alkyl Substances (PFAS) Monitoring of Surface Water and Fish Tissue
Author(s):Gorski, Patrick
Subject(s):per- and polyfluoroalkyl substances
Abstract:Presented by: Patrick Gorski – Research Scientist at WI Dept. of Natural Resources, Co-authors: Michael Shupryt, Meghan Williams, Timothy Asplund Abstract: In 2019, the Wisconsin Department of Natural Resources initiated pairwise sampling for PFAS in water and fish at major rivers throughout the state (e.g., Mississippi River, Wisconsin River, Menominee River, and others). The results of this statewide sampling effort contribute to three important PFAS-related initiatives: 1) assessing the distribution of PFAS in the environment, 2) rulemaking efforts to develop surface water standards for perfluoro-octane sulfonic acid (PFOS), and perfluorooctanoic acid (PFOA), and 3) determining need for PFOS-related fish consumption advisories. Both water and fish were sampled at multiple sites within rivers, and water was sampled at three different dates. Samples were analyzed for up to 36 PFAS compounds, to not only measure compounds for consumption advisories (i.e., PFOS), but also survey for the presence or absence for potential precursor compounds or compounds associated with potential anthropogenic uses. Concentrations of quantifiable PFOS ranged from 0.6 to 43.0 ng/L in water and 2.0 to 180 ng/g in fish. Differences were observed between and within river sites, as well as compound diversity. Differences between sites for PFOS in water and fish, and their respective bioaccumulation factors, suggest differences in bioaccumulation, which will require further sampling and study, and was continued in 2020. Biography: Patrick Gorski is an Emerging Contaminants Research Scientist at the WI Dept. of Natural Resources in the Bureau of Water Quality, where he started in April of 2020. His focus of research is PFAS in surface water, fish tissue and fate and transport issues. For the previous 13 years, he was an Assistant Scientist and Supervisor at the WI State Laboratory of Hygiene. He received his PhD from UW-Madison studying mercury bioavailability and bioaccumulation in freshwater systems.
