Road Salt is Polluting Our Water. Here's How We Can Fix It

Updated: Aug 8, 2021


Just a teaspoon of road salt pollutes 5 gallons of water — forever.  


And each winter, Minnesota dumps some 730 million pounds of salt on roadways. That's probably far more salt than we need to keep our roads safe.


Once snow melts, salt flows into lakes and streams. Once salt is in a body of water, it's nearly impossible to remove.
