Chloride 101

Minnesota waters need a low-salt diet

Minnesota has a growing salty water problem that threatens its freshwater fish and other aquatic life. Chloride from both de-icing salt  and water softener salts gets into lakes and streams, and groundwater that supplies drinking water. It takes only one teaspoon of salt to permanently pollute five gallons of water. Once in the water, there is no easy way to remove the chloride. To learn more, click here.

Road salt, water softeners, and fertilizer, manure, and dust suppressants all add salt to our water. Too much salt is bad for aquatic life like plants and fish, and is bad for drinking.
