Average chloride concentration (A) and expected number of individual days per year with concentration exceeding the USEPA chronic water quality criteria of 230 mg/L (B) from modeling results compared to urban land cover percentage in the contributing watershed. We analyzed water-quality data from 30 monitoring sites on 19 streams near cities in Wisconsin, Illinois, Colorado, Michigan, Ohio, Pennsylvania, Maryland, Texas and the District of Columbia. By the time of the Civil War, thousands of workers were producing over 225,000 short tons of salt by boiling. Chloride concentrations increased more rapidly than development of urban land near the study sites (fig. Dramatic impacts were observed on local, regional, and national scales.

Chloride, a key component of road salt (along with sodium), is soluble, highly mobile in water, and, at high concentrations, can be toxic to aquatic vegetation and wildlife. Locally: In Milwaukee, more than half of the samples collected from streams during winter deicing periods were toxic. Overall, increasing trends in chloride concentrations were likely caused by increased salt application rates, increased baseline conditions (the concentrations during summer low-flow periods) and greater snowfall in the Midwest during the latter part of the study. Road salt is here to stay. Coarse rock salt used for spreading on roads or pavements, now usually in order to melt ice or prevent its formation.

In 13 of the streams, chloride concentrations increased over the study period even during non-deicing periods such as summer, suggesting that chloride infiltrated into the shallow groundwater system in the winter and was slowly released to the streams throughout the year as baseflow. All of these sources are likely to contribute to these increasing chloride concentrations. A back road is a small country road with very little traffic. : Waxes - Amazon.com FREE DELIVERY possible on eligible purchases Colonial Americans were making salt by boiling brine in iron kettles during the time that the U.S. Constitution was being drafted.
