Quebec River Water Quality Monitoring Data

Physicochemical monitoring data from all stations in Quebec and St. Lawrence River water quality networks. The dataset includes parameters such as total phosphorus, nitrogen compounds, chlorophyll a, and fecal coliforms, used to calculate the Bacteriological and Physicochemical Water Quality Index (IQBP). Follow-up is conducted annually.

Use Cases

• Calculate the Bacteriological and Physicochemical Water Quality Index (IQBP) using parameters like total phosphorus, nitrogen compounds, and fecal coliforms.
• Analyze spatial trends in water quality by comparing chlorophyll a and pheopigments measurements across different monitoring stations.
• Monitor temporal evolution of water quality by tracking annual changes in parameters such as turbidity, suspended matter, and pH.
• Correlate land use categories from drainage area attribute tables with physicochemical parameters like dissolved organic carbon and conductivity.

Strengths

• Data originates from all stations in official monitoring networks for Quebec and the St. Lawrence River.
• Includes a defined set of 14 physicochemical and bacteriological parameters for water quality characterization.
• Annual follow-up ensures regular temporal monitoring of water quality evolution.

Limitations

• Specific row count, column count, and temporal coverage are not provided in the input.
• Data may have geographic bias, being limited to Quebec and the St. Lawrence River.
