Description
Heightened nutrient levels along the Bow River downstream of Calgary have long been a concern. In the 1970s and 1980s, high nutrient levels resulted in excessive aquatic plant growth resulting in low dissolved oxygen and the occasional fish kill. In the past, the high nutrient levels were primarily managed by placing concentration limits on point source discharges. The decision (in 2005) to discharge treated wastewater from Strathmore to the Bow River was a turning point. The environmental approval for the activity was successfully appealed to the Environmental Appeals Board (2007), who in their ruling emphasized that such decisions ought to be managed in light of their cumulative environmental impacts, particularly given that water quality guidelines were being exceeded.
