Surface Water Contaminants of Emerging Interest in Québec Since 2000

Québec's Main Directorate for Aquatic Environment Quality has monitored contaminants of emerging interest in surface water since 2000. The dataset includes sampling station locations, linked Excel files with contaminant concentrations, and associated drainage area land use data.

Use Cases

• Analyze contaminant concentration trends from linked Excel files across sampling stations over time.
• Correlate land use categories from the compiled table with detected contaminant types at specific stations.
• Map sampling station locations and their associated drainage area polygons for spatial analysis of contamination.
• Review station-specific reports produced from water samples to assess historical monitoring activities.

Strengths

• Monitoring data spans over two decades, with records beginning in 2000.
• Includes multiple linked data components: station locations, concentration files, reports, and land use tables.
• Data is provided in several interoperable formats including GEOJSON, CSV, and ESRI REST.

Limitations

• Specific row counts, column names, and sample concentrations are not directly provided in the core metadata.
• Primary analytical data resides in external Excel files linked per station, requiring separate access and integration.
• Land use data is compiled only for the last available year at the time of generation, limiting temporal comparison.
