• Description:
  A literature review was conducted on the following deicers used for snow and ice control: magnesium chloride (e.g., FreezGard Zero®, Ice-Stop™ CI, Caliber™ M1000, Ice Ban™ M50), calcium chloride (Liquidow*Armor*), sodium chloride (road salt and Ice Slicer®), Calcium Magnesium Acetate (CMA®), Potassium Acetate (CF7®), CMAK™ (mixture of CMA and Potassium Acetate), Sodium Acetate (NAAC®), and sanding materials. These deicers were evaluated for chemical contaminants, environmental effects, human health effects, corrosion, application rates, performance, cost, and advantages and disadvantages. For most of the deicers reviewed there were gaps in available information. Thus, additional studies would be necessary to further elucidate the potential impacts of the deicers. A summary of the water quality data collected by the U.S. Geological Survey (USGS) and the Roaring Fork Conservancy in the Roaring Fork watershed in Colorado is also provided. A qualitative worker survey was also conducted. Questionnaires were sent to 126 employees of the Colorado Department of Transportation and Roaring Fork Transit Authority having daily contact with deicers. Of the 69 employees that responded to the survey, 26% reported minor symptoms including eye, skin, respiratory, and intestinal irritation. It was not possible, based on the qualitative nature of the survey, to determine whether the symptoms were related to deicer use.
