Six watersheds in New Hampshire were studied to determine the effects of road salt on stream water quality. Specific conductance in streams was monitored every 15 min for one year using dataloggers. Chloride concentrations were calculated from specific conductance using empirical relationships. Stream chloride concentrations were directly correlated with development in the watersheds and were i...

Chloride is a relatively unreactive plant nutrient that has long been used as a biogeochemical tracer but also can be a pollutant causing aquatic biology impacts when concentrations are high, typically from rock salt applications used for deicing roads. Chloride inputs to watersheds are most often from atmospheric deposition, road salt, or agricultural fertilizer, although studies on agricultur...

Concrete bridge decks are prone to ice accumulation. The use of road salts and chemicals for deicing is cost effective but causes damage to concrete and corrosion of reinforcing steel in concrete bridge decks. This problem is a major concern to transportation officials and public works due to rapid degradation of existing concrete pavements and bridge decks. The use of insulation materials for ...

Cyanides are highly toxic and produced by various microorganisms as defence strategy or to increase their competitiveness. As degradation is the most efficient way of detoxification, some microbes developed the capability to use cyanides as carbon and nitrogen source. However, it is not clear if this potential also helps to lower cyanide concentrations in roadside soils where deicing salt appli...

M.F. MORSELLI and M.L. WHALEN Maple Research Laboratory Botany Department College of Agriculture and Life Sciences University of Vermont October 1987 FINAL REPORT We had two objectives in the study of sugar maples which showed signs of decline and stress on a roadside where deicing salt was used in the winter. One goal was to determine If tree stress is related to the levels offsodium and chlor...

Deicing road salts have been increasingly used in the United States over past 80 years. Previous studies shown that these can deteriorating effects on freshwater organisms. Here, we hypothesize introduction of to streamwater also boost aggregation mud particles suspended water column. Such aggregation, known as flocculation, enhances deposition rates and may lead increased accumulation fine sed...

Green infrastructure (GI) protects aquatic ecosystems from stormwater runoff caused by urban development. Bioretention (BR) is a typical GI system wherein routed to soil basin planted with vegetation and has been shown reduce deicing salt loads in surface runoff, but the removal mechanism of poorly understood. This study explores potential different types released BR transpiration. Six engineer...
