This report investigates the impact of various discharge conditions on the water quality of the Toronto waterfront between 1976 and 1983. Authored by D. J. Poulton and M. Griffiths from Ontario's Great Lakes Section, the study utilizes key indicators to map the spatial and temporal variations in water quality. The primary argument focuses on how nutrient levels, turbidity, and conductivity reveal distinct zones affected by both dry and wet weather discharges, highlighting seasonal and long-term trends.

This report serves as a detailed technical assessment of water quality in a specific urban waterfront environment over a defined period. The methodology, focusing on established indicators like nutrients and turbidity, suggests a rigorous scientific approach to understanding environmental impacts. The scope, covering eight years of data and considering multiple influencing factors, points to a comprehensive study intended for environmental scientists, policymakers, and urban planners concerned with water resource management.
