Development of Management Objectives for Water and Effluent Quality

In support of its Environmental Management Act permit, AngloAmerican’s Trend Mine in northeastern British Columbia required the development of site-specific water quality objectives and trigger values. Borealis was responsible for the derivation of water quality objectives and trigger values of six parameters, specifically: nitrite, ammonia, phosphorus, cadmium, biochemical oxygen demand, and dissolved oxygen. These trigger values were developed for approval by provincial regulators and for use by environmental monitoring staff at the mine.
