Salt & Deicing Chemicals

Salt, or sodium chloride, is the most commonly used deicer in Minnesota and the surrounding region.  While it is true that salt does exist naturally, high concentrations can have negative impacts on the environment.  Salt that is applied to roads, driveways, and sidewalks accumulates in the surrounding soil which is harmful to vegetation.  It can also be transported by stormwater and melting snow to surface waters, which disrupts aquatic life by eventually settling into a concentrated layer and creating a "dead zone" at the bottom of a lake or pond. 

Other alternative deicing agents are calcium magnesium acetate (CMA) and carbohydrate-based deicers such as beet juice.  However, in high concentrations, these alternatives can also have adverse effects on the environment. 

Whether you use large or small quantities of salt or other deicing materials, they should be stored such that they cannot potentially enter a waterway.  An airtight container is best for smaller quantities.

While a 100% environmentally friendly deicer does not exist, the best practice is only apply deicers where needed, and to NEVER OVER APPLY.  Not only is this cheaper, it limits the potential for negative environmental impacts. 

Also, near the end of the winter season, please remember to sweep up excess deicer and throw it in the trash.  Otherwise, it may eventually be washed into a sewer drain and eventually reach a river, lake, or pond.
