What’s your go-to solution to clear your sidewalks and driveways of snow? Most of us pull out the snow blower and shovel, and many grab the salt. Salt helps melt ice and protects drivers and pedestrians.
But salt can also harm the environment. Only one teaspoon of salt permanently pollutes five gallons of water.According to the Minnesota Pollution Control Agency (MPCA), an estimated 365,000 tons of salt is used in the metropolitan area each year. When the snow melts, the de-icing salt, which contains chloride, runs into nearby bodies of water. Chloride accumulates in the water and can harm aquatic wildlife. There is no feasible way to treat or remove chloride from the water.MPCA offers suggestions to reduce reliance on salt and help to keep our water safe.
