chloride levels were reduced by half when best practices were employed.
A recent comprehensive study by environmental researchers at the University of Waterloo and Environment Canada, examined whether the best practices as outlined in Canada’s Road Salt Code of Practice actually delivered the improved environmental outcomes they promised. The answer was a resounding, yes; best practices in salt management deliver significantly improved environmental results.
The study, “Assessing the Efficacy of Current Road Salt Management Programs,” conducted by Prof. Micheal Stone and a team of environmental scientists at the University of Waterloo and Canada’s National Water Research Institute examined how public and private sector snowfighters implemented Canada’s voluntary Code of Practice (largely based on the Salt Institute’s Sensible Salting program) and whether the new practices reduced chloride runoff and impacts.
The final report examined the effectiveness of best practices to manage chlorides in the environment. The groundwater monitoring data revealed that that chloride levels were half the original level that was present before best practices were employed clearly establishing that best practices provide significant environmental improvements.
