More than 160 people from throughout the Midwest attended the Freshwater Society’s 9th Annual Road Salt Symposium on Feb. 3 in Brooklyn Center. The attendees — ranging from transporation workers, to researchers, to watershed district administrators — learned about, and discussed, the latest research on chloride pollution in lakes, rivers and groundwater.
Experts also described the newest innovations in equipment, chemical alternatives and non-chemical alternatives to road salt that will decrease pollution.
One of the featured speakers, Cassandra McKinney, water resources manager for McHenry County, IL spoke about the impact chlorides from road salt have had on her region’s groundwater, which is the primary source for drinking water in the area. She described policies she developed for the county to mitigate these impacts. Click for a complete listing of speakers and downloadable pdfs of presentations.
