A 1995-1999 research program investigated passive wetlands treatment for metal-contaminated mine drainage at the United Keno Hill Mine in Yukon. Government of Yukon researchers constructed a pilot wetland, transplanted local sedges (Carex aquatilis), and monitored metal removal over one season. Initial results showed reductions in zinc, cadmium, manganese, and nickel concentrations, indicating potential for this treatment method in northern climates.
Use Cases
- Modeling metal attenuation in wetlands based on sediment analysis results
- Evaluating plant species suitability for bioremediation based on Carex aquatilis colonization data
- Assessing passive treatment system performance in cold climates based on the pilot study findings
Strengths
- Research spans multiple years (1995-1999) with follow-up investigations
- Focuses on a specific, hardy plant species (Carex aquatilis) for northern applications
- Reports concrete initial results for zinc, cadmium, manganese, and nickel removal
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Monitoring was limited to one season for the pilot wetland
