Objectives for this project were:<br />
1. monitor the quality <strong>and</strong> quantity of CSOs over several rain events;<br />
2. assess the toxicity of CSO discharges;<br />
3. characterize one sludge sample from sediment deposits on the bottom of the combined sewer<br />
overflow pipe;<br />
4. compare measured contaminant concentrations to the CSO water quality estimates developed in the<br />
GVRD’s Stage 1 Liquid Waste Management Plan (LWMP) Report;<br />
5. identify key contaminants within the CSOs which would be appropriate for initial dilution zone <strong>and</strong><br />
receiving water assessment studies; <strong>and</strong>,
