Our area does. It doesn't work quite as well as salt, but it isn't an environmental nightmare, either.

Remember the problem with the water in Flint? This was primarily due to their using salt on the roads, which washed off into streams, which in turn fed rivers - and Flint was getting their drinking water from these rivers.

The corrosive effect of the salty water was so bad that a local General Motors plant had to stop using it to wash their engine parts, because it was corroding the parts. So, imagine drinking that water.

Also, because it was so corrosive, it dissolved the lead in the pipes, which was the main reason it was such a disaster.
