With winter here, salt is top of mind for me. Let’s talk about the cost of using salt (and ice melter and de-icing products).
The obvious one is the cost of purchasing it. For that reason alone, it makes sense to spread only what you need and only when you need it. And did you know you can sweep up leftover salt to save for another time?
Not that money is a big deal for me, but if we’re talking money, it’s hard to put an exact dollar amount on the environmental cost of using salt.
According to the Environmental Commissioner of Ontario’s 2018 report (Volume 2 – Clean Water – Chapter 2 : page 87) the hidden cost of salt on infrastructure and the environment range from $200 to $470 per ton of salt applied.
A National Post article “The awesome price we pay” outlines some of the costs of using salt. The author writes “Dalhousie University estimated that it costs it an extra $15,000 in cleaning and maintenance each year just to repair all the damage salt does to floors and baseboards”.
What are the hidden costs of salt?
- Your drinking water. Since this is my blog I’ll start with me. The salt and other de-icing products spread on the ground can eventually mix with me. Over time this will make me – groundwater – taste salty.
- Sore paws. Have you ever watched a dog trying to walk through salt? Salt trapped in their paws can irritate and crack their skin.
- Damage to buildings and concrete surfaces. Salt is toxic and will eat away at outside structures (brick/concrete/sidewalks), doorways and flooring may become damaged, increasing repair costs.
- Health of soil, plants and landscaping. If sprayed with salt, vegetation can lose its hardiness to the cold and be killed by freezing temperatures and high salt levels.
- Footwear and clothing. Salt stains and can ruin footwear and clothing.
- Vehicles, bicycles and wheelchairs. Salt accelerates rusting, causing damage and increasing repair costs.
- Health of waterways for aquatic life. Salt changes water density, which can negatively affect the seasonal mixing of lake waters. This mixing is important to increase oxygen levels required by aquatic life for survival.
That’s my list. Do you have an experience to share about the cost of salt? Also, check out the Region of Waterloo’s website for tips on clearing snow and ice.
