What You Can Do to Fight Chloride Pollution - SOURCE FOR THIS ARTICLE MN DNR
When clearing winter walks
* Shovel early and often. The more snow and ice you remove, the less salt you’ll need.
* Sprinkle sparsely. Leave 3 inches between salt grains.
* Go lean. A coffee mug is adequate for a 20-foot driveway or 10 sidewalk squares.
* Use a tool. A handheld spreader can apply salt consistently.
* Wait for warmer weather. When ground temperatures are below 15 degrees, it’s too cold for ordinary sodium chloride to work.
* Use the right de-icer. Calcium chloride works at much lower temperatures than sodium chloride.
* Sweep up extra salt. If it is visible on dry pavement, it is not doing anything and will be washed into water bodies.
