Abstract	Reported is an examination of the use and effects of chlorides as de-icing products for removal of snow and ice from roads immediately following storms. Increasing evidence of detrimental side effects led to a closer look and more careful evaluation of the overall significance of the so-called "bare pavement maintenance." The side effects include deterioration of concrete highway structures, corrosion of automobile and shoe leather, chloride contamination of ground and surface water supplies, damage to roadside vegetation, and toxicity to fish and wildlife of excessive chloride. The chemistry involved is discussed as well as the application problems. Alternative programs are suggested. A bibliography is presented in the report as are selected data tables indicating Tons of Salt Used per Mile for Winter of 1969-1970 for Eastern Massachusetts, Effective Mixture Ratios of Sodium Chloride and Calcium Chloride, Established Sodium and Chloride Limits for Water Supplies, and Snow and Ice Control Costs.
