CMA IN WINTER MAINTENANCE: MASSACHUSETTS CONFRONTS ENVRIONMENTALL ISSUES

Nowhere are the problems caused by heavy use and improper storage of road salt better recognized than in southern Massachusetts. In recent years, millions of dollars have been spent there to remedy and prevent sodium contamination of private and municipal drinking water supplies and to protect sensitive agricultural areas. Calcium magnesium acetate (CMA) deicer is among the remedies. Districts 6 and 7 have three winters' experience using CMA. District 6 reports an average of 260 lb of CMA per lane-mile was used to provide the same level of service as 300 lb of salt per lane-mile. District 7 CMA application rates ranged from 205 to 300 lb per lane-mile. Both districts agree that the greatest drawback of CMA is its purchase price (over $600 per delivered ton). Another drawback is that CMA often takes longer to get started than salt, especially in colder, drier storms.
