Chloride is virtually impossible to remove from a waterbody. Once it's there, it's there for good. Just one teaspoon of salt contains enough chloride to pollute five gallons of water forever! And according to the Minnesota Pollution Control Agency, we apply an estimated 365,000 tons of salt in the Twin Cities metro area each year. And what's even worse is that research shows that 78 percent of that salt is either transported to our groundwater supplies or remains in our local lakes and wetlands.
For the whole month of December, a display all about smart salting is up at the Northtown Library in Blaine. The display is a collaboration between the Anoka Conservation District and the Coon Creek Watershed District. It provides information about chloride pollution in Minnesota along with easy ways for residents to reduce their salt use while remaining safe this winter. When done viewing the display, library patrons can virtually sign the Smart Salting Pledge to reduce their salt use this season.
