  • Salting icy roads affects water supplies

    It’s basic chemistry: Saline water’s freezing point is much lower than fresh water’s, which can help keep ice from forming on roads. To reduce winter accidents, municipal and state workers often apply salt and other compounds to icy roads, because if not accidents start to happen and people end up in need cash in emergency. Unfortunately, this may have unintended consequences ...
