One 2010study from the University of Waterloo found that a handful of "best practices" can reduce local chloride levels by half. It snows more in Georgia than South Carolina and it shows SC uses sand. Maybe Alaskans dont like road salt. Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius), and that includes ice on roadways. But even improved technology and data-sharing wont be enough, Shi said, to stop the flow of salt. While no perfect solution exists to keep our roads clear in winter, the number of tools available to public works departments continues to increase, allowing for a tailored approach to clear roads in an environmentally conscious manner without risking driver safety. Road salt can contaminate drinking water, kill or endanger wildlife, increase soil erosion, and damage private and public property. How do you clean a silver chain that turned black? # 24.5 million tons at $48.11 per ton. The EPA says this can reduce salt use41 to 75 percent and is best done two hours before the storm.

In New England, road salting is a necessity to keep people safe during snow or cold weather as they drive to work or take their kids to school. In 2013 the State launched, the "New Hampshire Road Salt Reduction Initiative" to address the high number of waters impaired by chloride (19 water bodies in 2008, and 43 in 2012). Deicing chemicals melt ice by lowering the temperature at which it melts.
