(Webinar) Chemical Contaminants in Lake Superior

Posted: August 19, 2025

Join us as we learn about chemical contaminants in Lake Superior. Mark your calendars for October 7, 2025, at 1 pm CT (2 pm ET) for a one-hour public webinar, Chemical Contaminants in Lake Superior, as part of our Let’s Talk Lake Superior! webinar series.

Learn the status and trends of toxic chemicals in Lake Superior and how Canada and the U.S. use key indicators to help assess the lake’s health. We will also explore how PFAS, or “forever chemicals,” are transported through the atmosphere and deposited into the water. Also learn how herring gull eggs have helped our understanding of chemical pollutants in the Lake Superior ecosystem.

Guest speakers include Jacob Orlandi (Canada Water Agency), Alex Frie (Minnesota Sea Grant) and Shane de Solla (Environment and Climate Change Canada).

This webinar is free, open to the public and recommended for anyone who is passionate about the Great Lakes!
