A Salty Situation - Protecting Our Water in Halton Hills
While road salt continues to be an effective and economical winter maintenance product, it also has undesirable effects. These include damage to infrastructure and vehicles, environmental impacts on land and water, and potential impacts to ground water. By practicing 'Salting Responsibly,' we can ensure the safety of our roads, walkways, and parking lots while also mitigating impacts to our environment and drinking water sources.
Environment and Climate Change Canada (ECCC) released a “Code of Practice for the Environmental Management of Road Salts” (Environment and Climate Change Canada, 2004). As part of the Code of Practice, Halton Hills maintains a Salt Management Plan (SMP) and reports status annually.
The Clean Water Act, 2006 was established to guarantee clean, safe, and sustainable drinking water for Ontarians by safeguarding sources of municipal drinking water, such as lakes, rivers, and wells. Source Protection Plans (SPPs) include policies that suggest or mandate actions to mitigate activities identified as threats to drinking water. Halton Hills is part of three Source Protection Regions, each with SPPs approved by the Ministry of the Environment and Climate Change.
Through its Salt Management Plan, the Town adheres to best practices, including:
Direct Liquid Application
What is it?
- Application of a brine solution directly on the roads surface.
- Brine is applied to designated roads in advance of a winter event, and when conditions are favourable.
* Salt Brine: A 23.3% sodium chloride solution.
Why we do this?
-
Prevents the accumulation of black ice, frost, and packed snow.
-
Helps to prevent snow from bonding to pavement.
Tips on How to Salt Responsibly Around Your Property
Road salt works well to melt ice and snow around your property but it also has long-term impacts on the environment. Check out these tips to clear your driveways, walkways and sidewalks and keep safe while using less salt!
-
Shovel or plow snow before applying salt. Salt will not work to melt the snow.
-
Spread salt sparingly and evenly, but remember, a little goes a long way! Using more salt won't yield better results. If you see salt left on the ground after the snow and ice clears, you are using too much. A few tablespoons of salt for a one-metre square area should do the trick.
-
Use alternative products to salt such as, grit, sand, or non-clumping kitty litter to help create traction.
-
Keep storm drains clear to help melting snow drain away from your property.
- Ensure your salt is contained in a proper container with a lid to prevent rain and snow from entering.
