Sudbury area lakes in Ontario have been monitored since 1981 for water chemistry. Twenty-two lakes were selected as a non-acidified reference set for intermittent baseline monitoring. The Government of Ontario provides data on acidity, nutrients, clarity, and metals.
Use Cases
- Monitor long-term pH and alkalinity trends based on acidity measurements
- Analyze the natural buffering capacity of lakes based on selected reference lakes
- Assess nutrient and metal concentrations in freshwater ecosystems based on water chemistry sampling
Strengths
- Data collection spans over 40 years, starting in 1981
- Includes 22 lakes specifically selected as a non-acidified reference set
- Water chemistry sampling includes multiple key components: pH, alkalinity, sulphate, nutrients, colour, clarity, organic matter, metals, and ions
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
