The winter of 2015-2016 started out with mild weather but snow may be around the corner. Winter is a time to think of how to best manage salt and snow.
Public safety means protecting people on roadways. Public safety also means protecting our drinking water sources.
This month our newsletter features salt and snow as the Best Management Practices Profile of the Month.
Our municipalities and source protection authorities have recently produced a new fact sheet, about salt and snow, for your information. You are invited to download this fact sheet now. (Medium-sized 300 kb PDF file)
Why does road salt pose threat to drinking water?
Road salt helps keep roads, sidewalks, and parking lots clear of snow and ice but it also has the potential to contaminate our municipal sources of drinking water. Sodium and Chloride in salt and other de-icing material may be washed into rivers and lakes or seep into groundwater. That makes it important to use best management practices in the storage and application of road salt to reduce risk to water.
What can we do to reduce road salt use?
- Shovel first. By removing ice and snow by shoveling or other means, you will need less salt.
- Use salt wisely. A little goes a long way but it needs time to work. And remember that salt doesn’t work when it’s colder than 10 degrees below zero (Celsius).
- Prevent icy areas. Redirect downspouts away from driveways and parking lots.

Storage of snow:
Snow removed from roads and parking lots may be contaminated with salt, oil, grease and heavy metals. Storing large amounts of snow in one area concentrates the contaminants. Once the snow melts, these contaminants may reach groundwater or surface water. This poses a threat to drinking water sources. That’s why it’s important everyone consider how and where you store snow.
Salt, Snow, and Planning Policies
Road salt storage, road salt application, and snow storage are some of the 21 activities that pose potential threats to the safety and quality of our municipal drinking water sources. Everyone should have regard for the policies in the local source protection plans and consider how they can help protect our drinking water.
We encourage you to find out more about best management practices for reducing the impacts of snow and salt and other activities. Visit your local website at this link: www.sourcewaterinfo.on.ca
Thank you for all you do to keep local drinking water sources safe and clean.
All the best of the season to you.
