The research analyzes the amount of salt being dumped onto roads and its effect on trees, specifically the Red Maple and Eastern Hemlock. The goal is to find an alternative to rock salt without completely eliminating its use. The experiment involves using three different alternatives-volcanic mineral, beet juice, cheese brine-and constructing a ratio between a baseline amount of salt and alternative. The result of this is to find the smallest amount of salt needed to efficiently melt ice and cause least damage to trees. Analyzing leaf water content will show which alternative works best.
