National Synthesis on Potential Sources, Fate and Transport, and Potential Effects of Chloride in Surface-and- Ground -Water Resources of the Conterminous United States

The objective of this proposed United States Geological Survey (USGS) investigation is to provide water-resource managers and decision makers with the information necessary to evaluate potential natural and anthropogenic Chloride (C1) sources in a watershed. Characterization of natural C1 concentrations can provide a baseline to evaluate the salt tolerance of the natural ecosystem and to evaluate the probability of water-quality exceedances without anthropogenic inputs. Characterization of anthropogenic C1 concentrations and loads can provide information necessary to estimate C1 inputs on the basis of land-use information. This information, which can be used to identify and evaluate the magnitude of potential sources, may be used by water-resource managers to evaluate methods to reduce various C1 sources throughout the watershed so that the number of water-quality exceedances may be reduced. This project will be comprised of a literature review, data mining and exploratory data analysis from the USGS national water information system Web (NWIS Web). This information and data will be collected, interpreted, summarized, and reported to the Federal Highway Administration (FHWA) for publication.
