A modeling-based method for assessing the potential impact of calcium magnesium acetate (CMA) on the dissolved oxygen in streams through biodegradation is presented. The method was applied to two example Illinois streams--the Kaskaskia River and the Boneyard-Saline Branch-Salt Fork-Vermilion river system, both of which receive urban and rural runoff. These two examples were chosen as pessimistic, involving small streams potentially receiving relatively large amounts of CMA biochemical oxygen demand. The method predicts that the oxygen degradation in the stream may be severe under the worst conditions, which involve the largest number of small successive snowfalls since records have been kept, after each of which CMA is assumed to have been applied, as well as stream ice cover, which prevents reaeration. Both example streams are predicted to go anaerobic over part of their length. However, if only the stream ice cover is assumed not to exist, thus allowing aeration, the dissolved oxygen impact is, although significant, insufficient to violate the prevailing stream standard of 5 mg/L. The results suggest that in Illinois streams the oxygen-depletion impact of CMA may be severe but that such instances will be relatively uncommon; more often the impact will be well within that which can be assimilated by the stream.
