Polluted Snow Can Degrade the Bay

Posted on Apr 16, 2010

While snow may appear to be as pure as, well, the driven snow, it is anything but. Plowed snow can contain pollutants like road salt, motor oil, trash and grime gathered from city streets, even air pollution scrubbed from the atmosphere by falling snow. As the snow melts, these pollutants can end up in Casco Bay, damaging water quality and marine life.
