Chloride concentrations are increasing at a rate that threatens the availability of fresh water in the northeastern United States. Increases in roadways and deicer use are now salinizing fresh waters, degrading habitat for aquatic organisms, and impacting large supplies of drinking water for humans throughout the region. We observed chloride concentrations(More)
Sodium and chloride concentrations and export increased from 1986 to 2005 in a rural stream in southeastern New York. Concentrations increased 1.5 mg/L per year (chloride) and 0.9 mg/L per year (sodium), and export increased 33,000 kg/year (chloride) and 20,000 kg/year (sodium) during this period. We estimate that salt used for deicing accounted for 91% of(More)
Widespread use of salts as deicing agents on roads has been perceived as a significant source of environmental and economic damage. Early studies focused on near-road and short-term effects where concentrations can exceed several grams per liter. Evidence is accumulating that the use of salts has significant effects over broader areas, longer time frames,(More)
In much of the world, rapidly expanding areas of impervious surfaces due to urbanization threaten water resources. Although tools for modeling and projecting land use change andwater quantity and quality exist independently, to date it is rare to find an integrated, comprehensive modeling toolkit to readily assess the future course of urban sprawl, and the(More)
Ammonium (NH(4)(+)) concentrations in air and precipitation at the Institute of Ecosystem Studies (IES) in southeastern New York, USA declined over an 11-year period from 1988 to 1999, but increased from 1999 to 2001. These trends in particulate NH(4)(+) correlated well with trends in particulate SO(4)(2-) over the 1988-2001 period. The NH(4)(+) trends were(More)
Climate change predictions for the northeastern US call for an increase in tropical storms and a decrease in extra tropical cyclones including continental storms. We ran 24-h back trajectories for each precipitation event that occurred at the Cary Institute of Ecosystem Studies in southeastern New York, U.S.A. from 1984 to 2007 and analyzed precipitation(More)
