New Hampshire Road Salt Reduction Initiative

Dramatic and rising concentrations of Chloride from road salt have been identified in New Hampshire waters and mirror a trend that is being seen by other states in the US and Canada due to the application of de-icing chemicals. In 2008 New Hampshire listed 19 chloride impaired water bodies on the 303(d) list under the Clean Water Act. In 2010 that number increased to 40. Chloride can lead to a reduction in the diversity of aquatic species, a decrease in dissolved oxygen and an increased nutrient loading which promotes eutrophication in lakes. more…
