The Minnesota Pollution Control Agency (MPCA) says statewide about 404,000 tons of road salt are used every year.
Road salt is a vital tool in making roads safer in snowy and icy weather, but it can do some real damage to your vehicle.
The St. Regis Mohawk Tribe is using new technology to reduce salt pollution, outfitting snow removal trucks with cameras and sensors to track salt use and optimize operations.
