As the freeze and thaw season has made its way into our lives again, treacherous walking and driving becomes a routine ordeal. Properly maintaining walkways, roads and parking areas by clearing the snow in a timely fashion is the best way to help prevent accidents, but we often use deicing salts to maintain these areas too. They work to decrease the freezing point of water, preventing ice from forming in temperatures from 20 to -30F depending on the formulation. Deicing salts certainly have their benefits, but they can also cause unnecessary issues for plants, ground water and aquatic life. Sodium chloride is the most commonly used formulation, but there are many others. Some even include things like beet juice, or cheese brine to help slow corrosion and improve application. Using deicing salts properly is key to best performance and reducing the negative impacts on the environment, so be sure to apply them at the proper temperatures, only in critical areas, and sparingly. There are formulations specific to temperature such as calcium chloride which are more appropriate for negative temperatures, but again be sure to read the application directions. Avoid leaving piles of the deicer, and try to remove all snow rather than applying on snow. If there is dry salts leftover that can be swept up, it can be reused when stored properly. This is a great way to help prevent excess from entering our groundwater and waterways.
