As winter settles in, Minnesotans often rely on deicing chemicals to ensure safer driveways, sidewalks and roadways.
Using these substances responsibly can minimize environmental harm and preserve infrastructure.
Proactive Maintenance Reduces Salt Use
One of the most effective ways to reduce reliance on deicing chemicals is through proactive maintenance. Regular shoveling, scraping and sweeping can remove snow before it turns to ice. By keeping surfaces clear, you’ll need far fewer deicers.
If deicing salts are necessary, apply them correctly and sparingly. For every 1,000 square feet — roughly the size of a 20-foot driveway or 10 sidewalk squares — just a coffee mug’s worth of salt (12 ounces) is sufficient.
Spread it evenly, leaving about three inches between each grain. Be sure to sweep up leftover salt to prevent contamination of local waters.
Environmental Impact of Overuse
Excessive salt use can cause significant environmental and infrastructure damage. Just one teaspoon of salt can pollute up to five gallons of water, contributing to groundwater contamination and harming aquatic life.
Chloride in deicing salts can also damage concrete, asphalt, natural stone and metal surfaces. By minimizing salt use, you can protect both the environment and your property.
In Sum
Minnesota’s most sustainable deicing solutions include Calcium Magnesium Acetate and Potassium Chloride, both of which are safer for the environment than traditional sodium chloride.
Sand is a great non-toxic option for traction, though it doesn’t melt ice.
By applying these alternatives responsibly and following smart salting practices, you can help preserve the environment, and our beloved water bodies downstream, while ensuring a safe, clean winter.
