St. Lawrence River Bacteriological Water Quality Monitoring

2026 data from an exploratory monitoring program assesses water health along the St. Lawrence River banks. The dataset determines risks to human health and suitability for swimming, highlighting improvements from wastewater overflow reduction or disinfection equipment installation.

Use Cases

• Map water health index values along the river to identify potential bathing site locations.
• Analyze bacteriological quality trends to measure impacts from wastewater overflow reduction efforts.
• Correlate monitoring results with rainfall events to assess pollution risks during wet weather.

Strengths

• Data is current, with a last update in March 2026.
• Sourced from the authoritative Government and Municipalities of Québec.
• Available in multiple geospatial formats including GPKG, GEOJSON, and ESRI REST for flexible analysis.

Limitations

• Specific data volume (row count) and feature details (columns) are unknown, limiting assessment of analytical scope.
• Relies on automated translation for original metadata, which may introduce ambiguities in data descriptions.
