Each year for the past 10 years, Minnesota has applied about 200,000 tons of salt on the state highways. In addition, we use probably the same amount again on our city and county roads, parking lots, sidewalks and driveways. These chemicals stay in our environment and out of our thinking since they are “invisible.”
Connie Fortin explains the environmental concerns about the use of roadsalt and how winter maintenance professionals can take practical and cost-saving steps to reduce their application rates in the magazine”Roads & Bridges,” in Fear for Water May 5, 2015. She also discusses how changes in public expectations and behaviors could help reduce salt use in Minnesota LTAP Technology Exchange Vol. 24 No. 1.
