A sampling program by the Government and Municipalities of Québec assessed the effects of a spill on sediment quality. It compared analysis results from samples taken before, during, and after the spill near overflow outlets, fish habitats, and downstream deposition zones. The dataset was last updated on April 17, 2026.
Use Cases
- Compare sediment contamination levels based on sampling before, during, and after the spill.
- Assess impacts on fish habitat based on station distribution near overflow points.
- Evaluate downstream deposition effects based on stations located several kilometers away.
- Analyze physico-chemical parameters to understand changes in sediment quality.
Strengths
- Data is structured for comparison across three distinct time periods: before, during, and after the spill.
- Sampling stations are distributed to assess impacts at specific locations: near outlets, in fish habitat, and downstream.
- Available in CSV and XLSX formats for flexible analysis.
- Licensed under CC-BY-4.0 for open use.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific spill event in the Sorel Islands delta.
