"Hamilton Harbour is one of the 17 Areas of Concern in Canada designated by the International Joint Commission as requiring a Remedial Action Plan. This position paper was written in response to a proposal to artificially aerate the hypolimnion of Hamilton Harbour. The causes of eutrophication problems and the causes of hypolimnion oxygen depletion are reviewed. The priority of oxygen depletion as a problem to be repaired specifically is examined and found to be low. Interactions between nutrient and contaminant issues exist but their importance is likely small compared to benefits to be derived from better wastewater treatment. The plan of increasingly stringent sewage treatment and/or diversion is supported. Artificial aeration does not seem likely to solve any problems"--Management perspective.
