One in x of them reached a threshold where scientists worry nigh impacts on aquatic life. These can help prevent salt overuse, and they're already being rolled out in some cities. Present-day deposits of rock salt were formed by widespread evaporation of ancient inland seas.4 Rock salt deposits are geographically diverse, but consumption of rock salt is concentrated in the Great Lakes region (see map on reverse). Road crews use salt on roads and other surfaces in the winter Salt lowers the freezing point of water, which prevents ice from forming Salt loses its effectiveness once the temperature falls below 15 degrees In addition to clearing snow and ice from roads, plows also put down a lot of salt on roads and other surfaces this time of year. Chloride, in particular, doesn't get filtered out naturally by soil and accumulates in waterways. All donations matched! Instead, its going to be crucial to encourage safer winter driving habits like asking people to stay home during storms whenever possible, or to drive more slowly even on a highway. As with all highway maintenance activities, there are environmental implications from winter road maintenance, the organization said in a statement.
