As we march through the thick of winter, salt — that granular ally against slips and skids — becomes a near-ubiquitous sight on pavements and roads. But what seems a necessary defense against ice’s peril carries with it an environmental toll, one that the City of Charlotte is urging residents to consider. In a recent statement, the city shared methods for reducing salt use, thereby protecting our streams and lakes from rising chloride levels that threaten aquatic ecosystems.
The traditional throwing of salt can lead to over-application and, in the aftermath of a thaw, all that excess gets washed away into our water systems. In Charlotte’s strategic stance, they’re not just tossing salt willy-nilly; they calibrate their equipment ensuring brine and salt are spread at the proper rates.
For those looking to tread lightly on the environment, creating a brine solution — a mix of salt and water — before snowfall or an icing event is recommended. This preemptive strike helps prevent ice from gripping the ground too tightly. When temperatures lurk above 18 degrees Fahrenheit, this is a solid choice; dip below 15 degrees, and alternative materials or strategies may be required…
