Salt that is applied to our roads, parking lots, and sidewalks ends up in our lakes, streams, and wetlands, negatively impacting those water resources. Salt has other negative impacts, such as harming vegetation, including turf, and altering the process of infiltration into soil.
This page provides information on education resources for salt management. Included are links to fact sheets, websites, and videos.
The MPCA worked with the Mississippi Watershed Management Organization, the University of Minnesota, and Fortin Consulting to produce a 20-minute video that introduces best practices for winter maintenance of small spaces such as sidewalks, entryways, and steps. Guidance includes deicer material selection and application rates. Links to Part 1 and Part 2 of this are shown to the right.
If you hire out snow removal for your property, choose a contractor who is certified by the state in Snow and Ice Control Best Practices or encourage them to become certified. This list of certified practitioners is maintained by MPCA and can be accessed as an File:Road salt training certificate holders.xlsx.
Many local lakes and streams have elevated levels of chloride, a common ingredient in road salt. In some cases, the chloride contamination is high enough to impact or even kill fish and other aquatic life. Winter snow and ice practices have been identified as the primary source of this chloride. Certified contractors have taken a training on how to mitigate the effects of de-icing materials on the environment, without compromising safety or effectiveness.
Voluntary certification in Snow and Ice Control Best Practices from the MPCA is given to individuals who
