Deicing agents for removal of ice and snow from highways and streets are considered essential for wintertime road maintenance in most areas of the U.S.A. However, heavy usage of highway-deicing materials can result in injury and damage across a wide environmental spectrum. Salt-laden runoff from streets, highways, and storage facilities can result in damage to public water supplies, ponds, lakes and surface streams; roadside soil, vegetation and trees; highway structures and pavements; vehicles; and underground utilities. The total annual national cost of salt-related damage is estimated at 5.4 billion dollars. The paper outlines the results of several studies on highway-deicing impacts characterization and control conducted by the U.S. Environmental Protection Agency's (EPA's) research program on urban stormwater and combined sewer overflow pollution control in the 1970's. The widespread environmental impacts from roadway salting are reviewed and recommendations are provided for salt usage, storage, and equipment maintenance. In addition, various methods for anti-icing/deicing are presented. This includes the results of several studies evaluating and optimizing hydrophobic pavement coating materials. Recommendations for future research to reduce the adverse impact of highway deicing are described.
