Watcher, there are always environmental arguments in cities that use salt or chemicals for snow and ice for roadways or airports, because they do contaminate soil and any water catching runoff. Salt is also a contaminant. Have you ever seen a lot of bare earth along roadways that use salt? I doubt it...it would take a lot of salt to kill off vegetation. A lot more than they use on roadways. By the time you put down enough to keep your driveway clear, you'd be wiping out any gardens and lawns it can run off into. And contaminating groundwater, streams, etc. And salt doesn't go away. It ruins the soil forever.
