Step 9: Confirmatory Sampling

Navigate between each steps Step 1: Site Identification Step 2: Historical Review Step 3: Initial Testing Program Step 4: Initial Site Classification Step 5: Detailed Testing Program Step 6: Site Reclassification Step 7: Develop Risk Management Strategy Step 8: Implement Remediation/Risk Management Strategy Step 9: Confirmatory Sampling Step 10: Long-Term Monitoring

During Step 9, confirmatory sampling is conducted to ensure that risk management objectives (e.g., contamination has been removed or stabilized effectively) have been met during and immediately following the implementation of the Risk Management Strategy (RMS).

How to Prepare

  • Review:
    • the confirmatory sampling design;
    • other sampling reports (e.g., pre-activity, reference sites).

What to Do

  • Finalize and implement site-specific confirmatory sampling plans.
  • Develop and implement an adaptive management plan, if necessary.
  • Determine if the risk management objectives were achieved.
  • If long-term monitoring (Step 10) is not required, proceed to site closure; Prepare a final report that documents all activities carried out during site remediation, decommissioning, and clean-up, which includes drawings, records, and sampling data.

How Fisheries and Oceans Canada (DFO) Expert Support Helps

  • Review and provide advice on the results of the confirmatory sampling.
  • Advise on the effectiveness monitoring in relation to the protection of fish and fish habitat, as well as aquatic ecosystem sustainability.
  • Provide advice on the design and expectations associated with the long-term monitoring plan.
