We all know that using deicing salt on sidewalks and driveways helps melt winter's mess and make these surfaces safer to walk and drive on, but it comes at a price. Sodium chloride, when it melts the ice, turns into a liquid mixture that ends up in our rivers, creeks, lakes and other waterways. This salt can change aquatic habitats and create dead zones, killing fish and amphibians. While there is no real eco-friendly solution to deicing salt, what you can do is use less of it. Try mixing salt with sand, and spread that 50-50 mixture instead. It will help melt the ice, and the sand will provide traction where you need it.
