Road Salt Is Imperiling Aquatic Ecosystems. It Doesn't Have To.

An experiment in upstate New York showed how town officials could maintain clean and safe roads during the winter season and protect the environment. By using a salt brine before winter storms, they were able to plow the roads more efficiently and, at the same time, reduce the amount of salt going into waterways that could impact freshwater ecosystems. The effort, launched by the nonprofit FUND for Lake George, required “a culture shift within the towns’ maintenance departments,” but the communities were able to cut their salt usage in half over two years.
