Driving in the winter in certain areas of the world is tough due to the icy conditions. In order to make life easier, we use road salt - it helps melt ice by reducing the freezing point of water. But have you ever thought about the impact road salt has on the environment?
It is commonly known that road salt is harmful for plants and animals. But another impact that most people don’t know about is that it pollutes groundwater. When salt is applied to roads, it can wash away with snow or rain, and end up in water sources like streams, rivers, and aquifers. This leads to abnormally high concentration of salt in those water sources, which can be detrimental to the health of people, plants, and animals that rely on the impacted water sources.
Road Salt
But it's not just the direct impact on water quality that we have to worry about. Road salt can also harm the environment by killing plants that grow alongside the road. Without these plants, the soil can erode and cause other problems.
So, knowing the negative impact of road salt on the environment, what can we do to reduce the pollution caused by road salt? One solution is to use alternative de-icing agents like calcium magnesium acetate or potassium acetate. These alternatives are less toxic and don't have the same impacts on the environment as road salt.
Another solution is to use road salt more efficiently. This can mean applying it more sparingly, using it only on high-traffic areas, or combining it with other de-icing methods like sand or grit. It is unnecessary to use excess road salt, as that harms the environment more than it needs to.
Finally, communities can invest in infrastructure that captures and filters salt before it gets into waterways. This can include catch basins, filters, and other types of treatment systems. However, this solution will be costly and time-consuming, as installing new infrastructure is expensive and is a long process.
Road salt is an important tool for keeping us safe in the winter, but it's important to consider the environmental impact it can have. By using alternative de-icing agents, using road salt more efficiently, and investing in infrastructure that filters salt out of the water, we can reduce the pollution caused by this necessary winter tool. Think about how much road salt is used, and how much road salt needs to be used. The next time winter comes, be sure to use road salt efficiently!
