CHEMICAL DEICERS MAY RANGE FROM UREA TO ROCK SALT. ABOUT THE ONLY REQUIREMENTS ARE THAT THE SUBSTANCE BE SOLUBLE IN AND LOWER THE FREEZING POINT OF WATER. CHLORIDES ARE DISCUSSED IN APPLICATIONS TO STREETS AND HIGHWAYS, WATER SUPPLIES, AND SEWAGE AND WASTE. NITROGEN AND PHOSPHORUS DEICERS ARE NOT SATISFACTORY FROM THE STANDPOINT OF FUTURE SURFACE WATER QUALITY. HOWEVER, A NONCORROSIVE MIXTURE HAS BEEN PATENTED FOR THE CHEMICAL REMOVAL OF ICE AND SNOW AT AIRPORTS. A FEW OTHER DEICERS ARE DISCUSSED.
