Road Salt Alternatives Alter Aquatic Ecosystems

Jefferson Project researchers test effects of common road salt, additives, and alternatives Organic additives found in road salt alternatives — such as those used in the commercial products GeoMelt and Magic Salt — act as a fertilizer to aquatic ecosystems, promoting the growth of algae and organisms that eat algae, according to new research published today in the Journal of Applied Ecology. Low levels of magnesium chloride — an alternative type of salt found in the commercial product Clear Lane – boost populations of amphipods, tiny crustaceans that feed on algae and serve as an important food source for fish.
