Description:   The detrimental effects of slag on five aquatic species, discovered in bioassay tests, motivated Cominco to advance the startup of a land-based tail slag storage system.  The treated slag was traditionally discharged to the Columbia River, British Columbia, Canada at a rate of 360 tonnes/day.  The bioassays identified excessive copper and zinc levels, as well as slag caused physical abrasion, as the contributing factors to the detrimental effects.
