Is road salt harmful to the environment?
There have been no findings that prove road salt is harmful to humans. In 2001 Environment Canada released an assessment report stating that road salts are entering the environment in large amounts and are posing a risk to plants, animals, birds, fish, lake and stream ecosystems, and groundwater. Environment Canada has classified road salt as toxic under the Canadian Environment Protection Act (CEPA). The toxic designation means that road salt is harmful to the environment when used in excessive amounts. Environment Canada has not banned road salt.
