Quebec Contaminated Land Sites and Rehabilitation Records

Quebec's contaminated land directory compiles information on sites affected by industrial, commercial, or accidental spills, including rehabilitated areas. The data is georeferenced within the province's Operations Management Assistance System (SAGO). It is maintained by the Government and Municipalities of Québec.

Use Cases

• Map georeferenced intervention sites to analyze spatial patterns of contamination from industrial and commercial activities.
• Track rehabilitation status of contaminated land parcels over time using site records.
• Cross-reference contaminated land files with other environmental datasets via the SAGO system identifiers.

Strengths

• Data is georeferenced, allowing for spatial analysis and mapping of contaminated sites.
• Includes records on both active contaminated sites and rehabilitated land.
• Managed by the authoritative Government and Municipalities of Québec.

Limitations

• The dataset is not an exhaustive inventory, only compiling cases brought to the ministry's attention.
• Sample data and specific column schema are unavailable for review prior to download.
• Data is provided in multiple formats (PDF, GPKG, FGDB) which may require specialized tools for full use.
