CORROSIVE EFFECTS OF DEICING SALTS
A STUDY IS REPORTED OF THE CORROSIVE EFFECTS OF DEICING SALTS CONDUCTED IN MILWAUKEE. A REVIEW IS PRESENTED OF PUBLISHED INFORMATION AND ANALYSIS OF THE PROBLEM. PRESENT STUDIES SHOW THAT THE DEICING SALTS DO PENETRATE TO THE LEVEL OF WATER MAINS. THE CHEMICAL CORROSION ON LEAD SHEATH CABLES BY SODIUM HYDROXIDE WOULD BE EXPECTED TO CAUSE SIMILAR REACTIONS ON LEAD PIPE JOINTS. THE INCREASE IN STRAY AND GALVANIC CURRENT FLOW OWING TO THE LOWERING OF SOLID RESISTIVITY AND THE FORMING OF GOOD ELECTROLYTES WILL HAVE THE SAME CORROSIVE EFFECTS ON BURIED CAST-IRON PIPE AS WAS SHOWN FOR CABLES. THE INCREASED CORROSION RATES SHOWN FOR AUTOMOBILE PANELS TESTED IN CITIES USING DEICING SALTS, OVER CITIES NOT USING SALTS, WOULD PROBABLY SHOW SIMILAR RESULTS ON BURIED PIPE IN THE SAME CITIES. THE COSTS OF DEICING-SALT CORROSION ARE NOW HIDDEN IN CONSUMER GOODS PRICING, UTILITY OPERATING COSTS, AND TEXES.
