One of the biggest concerns in winter is the problem of how to deal with ice on the roads. Currently the most popular method for dealing with this problem is with the use of sodium chloride (table salt). Sodium chloride is used because it is very inexpensive, but it does have its downsides. Sodium chloride does corrode steel in cars, trucks and reinforcing rods in concrete. When the sodium chloride is dissolved, the sodium and chloride ions do not get filtered naturally by soil. Instead, they run off into our waterways. Scientists have been working to find an alternative to salt and have come up with a few solutions. Instead of using sodium chloride, calcium chloride or magnesium chloride can be used as alternatives. Another solution to using a large amount of sodium chloride to deice our roads, would be to create a solution of water and sodium chloride. This solution would be applied to the roads about to 2-3 hours before snowfall and would drastically cut to amount of salt needed to deice the roads.
