Cold winters in the Northeast drive communities to apply winter de icing salts to roads and walkways While effective, the salt applications create long term water quality and ecological issues on the local and regional water system. The purpose of this research was to understand the interaction of sodium with water and soil in the Centennial Lake Watershed, which is a part of the larger Delaware River Watershed that supplies potable water to Pennsylvania, North Jersey, and New York state Our result indicates there are three components in the sodium source in water road salt, mineral dissolution, and precipitation deposition Sodium absorption can mobilize other metals in the soil through a cation exchange process, while complexes of the chloride can also help mobilize other metals, including mercury in the water Compared to the sodium levels in stream water measured 10 years, its average concentration is more than 25 higher in the off snow season today.
