摘要: AbstractRoad salt (NaCl) application around Lake George, New York, resulted in nearly tripling in-lake concentration between 1980 and 2009. Salt concentrations measured 8 streams 2007 2009 ranging development from pristine to moderate 4 significantly different groups based on chloride concentrations. Chloride were correlated the amount of roadway surface within each sub-watershed, with most impacted stream approaching 200 mg/L. In more streams, chlor­ide inversely discharge rate. The high road density developed south end accounted for ∼30% estimated application, which created a gradient lake that decreased as water flowed north single outlet. continual disproportionate input near southern strengthened over time create significan...
