Proper Winter Salting Protects Local Waterways
December 24, 2020
According to the Minnesota Pollution Control Agency (MPCA), it takes only one teaspoon of salt to permanently pollute five gallons of water. Knowing how to salt correctly keeps local streams, rivers, and lakes cleaner and protects habitats, fish, and plants.
Shoveling early and often during snow storms limits the chances of the snow on the ground turning to ice. Once the storm has passed and you’ve finished shoveling, you can assess how much salt you really need to use, if any.
Know When To Salt
Most salt doesn’t work below 15 degrees. Sand is a safe alternative when temperatures are too cold.
Know How Much Salt To Use
Experts say there should be 2–3 inches between each grain of salt. Try using a hand spreader to make the job easier and more accurate, maximize effectiveness, and avoid over application.
Sweep Up Leftover Salt
If there is no ice left on your driveway, sweep up the remaining salt for future use and to keep it from flowing into storm drains.
