Fresh water affected by salt from deicing roads

Frostburg, Md. (Sept. 1) Scientists have found that fresh water systems from across the northeastern United States including Baltimore, Maryland the Hudson River Valley, New York and the White Mountains of New Hampshire are becoming saltier due to deicer use on roads during the winter. Not only are there more roads, but the amount of deicing that occurs is increasing and gradually adding salt to fresh water systems reports Sujay Kaushal and colleagues in the September 2005 issue of the Proceedings of the National Academy of Sciences.

The scientists used historical records over the last 30 years and direct measurements to quantify changes in baseline salinity and predict what would happen if trends of urbanization and deicer use continue. By accumulating in groundwater and aquifers, some water in the northeastern U.S. already exceeds the recommended standard for the protection of aquatic life of 250 mg/l of chloride. In developed areas of Baltimore, chloride concentrations were already high enough to induce mortality in aquatic animals and alter wetland plant composition. During the winter months chloride in urbanized areas can increase in waterways to as high as 5 g/l which is equivalent to 25% of seawater concentrations.

Dr. Kaushal of the University of Maryland Center for Environmental Science Appalachian Laboratory said, "There is a direct connection between the rate of construction of new roadways and parking lots and the quality of our fresh water. In particular, we have not paid enough attention to rapid changes in human development and deicer use in watersheds that supply our drinking water and provide habitats for many species of aquatic life."

Dr. Peter Groffman, of the Institute of Ecosystem Studies, notes, "It is surprising and significant that the long-term record shows that salinity concentrations are going up, even in places where the amount of salt applied has not increased. Concentrations are high in the su
