• During certain periods, snowmelt can contain elevated salt levels
• Snowmelt runoff from major stormwater outfalls can be collected
• Recycling will reduce chloride peaks in the streams without adversely affecting road safety
The Salt Institute has long supported research in a broad area of study supporting environmental protection. One such area is the management of stormwater runoff during peak winter maintenance periods. By using real-time modeling methods, researchers at the Guelph University studied the possibilities available for optimal stormwater management. The City of Toronto cooperated in this study by setting up several continuous water quality monitoring stations to establish background chloride concentrations and to evaluate the effectiveness of its model management practices.
The Guelph researchers used the EPA Storm Water Management Model to simulate runoff and a computerized storm water containment model was employed to manage any possible spikes in in chloride levels. Analyses of streams led to the design of computer-controlled stormwater containment systems to serve as a guide for future mitigation applications.
