Ottawa River Basin Water Quality Monitoring Data for Nutrients and Metals

Long-term freshwater quality monitoring data for over eight sites in the Ottawa River basin spans 15 years or more. Environment and Climate Change Canada collected data on nutrients, metals, major ions, and other physical-chemical variables to assess status, trends, and regulatory effectiveness. Data from provincial sites is available through Quebec's Sustainable Development, Environment and the Fight against Climate Change Ministry.

Use Cases

• Analyze long-term trends in nutrient concentrations based on the 15+ year monitoring period
• Detect emerging water quality issues based on monitoring for metals and major ions
• Assess the effectiveness of remedial measures based on data collected to track regulatory decisions
• Establish regional water quality guidelines based on physical-chemical variable data

Strengths

• Data covers over eight monitoring sites
• Temporal coverage spans 15 years or longer
• Includes multiple variable types: nutrients, metals, major ions, and other physical-chemical data

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
