ABSTRACT
Effects of highway salting practices on the water quality of streams are evaluated in this study. The study surveyed winter salting practices on highways in Rhode Island. Field investigations included stream flow measurement data and water sample collections. A subsequent chemical analysis was conducted for water samples. Statistical analyses were performed to derive empirical equations correlating sodium and chloride concentrations of streams to land use type. Among various land use types, the highway was the only significant factor to explain sodium and chloride concentrations in the stream based on statistical analyses.
Keywords: highway salting | water quality | sodium | chloride
