Conduct effluent plume delineation: chapter 4
Reporting
Reporting of the study results should include the following:
1. Summary of information collected to aid in developing the conceptual model of effluent plume behaviour, including:
- description of the effluent in terms of flow, temperature, specific gravity and TSS (if applicable)
- description of the effluent discharge configuration and performance
- description of the receiving environment in terms of flows and currents, physical and chemical water quality (e.g., thermal and salinity variation horizontally and vertically), climatic conditions, and any other relevant site-specific parameters used to develop the conceptual model of plume behaviour
- confounding conditions, such as pulp and paper mill upsets, atypical climatic conditions
2. A conceptualized model of plume behaviour.
3. Documentation of tracer study conducted, including:
- pre-tracer laboratory testing, fluorometer calibration curve
- pre-trial field testing
- trial field tracer measurements
4. The Numerical model used and mapping depicting predicted plume envelopes for:
- maximum extent (1% and 0.1% effluent concentrations)
- long-term average conditions (1% and 0.1% effluent concentrations)
Computer animation is a useful option for depicting effluent plume behaviour in more complex receiving environments, such as estuaries and coastal locations.
The measured tracer concentrations should be provided in the appendix of the report.
