Includes bibliographical references (page 5). "Measurements of eutrophication indicators dissolved oxygen, phosphorus, chlorophyll, ammonia, Secchi depth were made in Hamilton Harbour 1988-1991. The data indicate beneficial responses to preliminary control of combined sewer overflows and operational improvements at sewage plants. Dissolved oxygen is resistant to change. Most water quality aspects have not improved sufficiently to restore uses to the Harbour. Pore water ammonia linked to discharges at STPs may have the potential to cause apparent toxicity in sediment assessments"--Abstract.
