Urgent Call to Prevent Environmental and Health Risks from Proposed Contaminated Soil Land Treatment Facility in the Alsek Valley
A local company, Castle Rock (supported by Dakwakada Capital Investments), has proposed a contaminated soil Land Treatment Facility (LTF) in close proximity to Kluane National Park, a UNESCO World Heritage Site, and sensitive natural habitats. This project raises significant concerns regarding public health, environmental preservation, and community well-being.
Key Issues with the Proposed Site Location
Extreme Wind Conditions: The Alsek Valley corridor is known for exceptionally high winds, with recent studies indicating gusts 3-5 times stronger than those in nearby Haines Junction. This high-wind environment poses a serious risk of airborne contaminants, including heavy fertilizers and sulfates required for soil treatment in cold climates, to become widely dispersed. Airborne pollutants could compromise both human health and the fragile ecosystem surrounding Kluane National Park.
High Risk of Contaminant Leaching: The site is situated on highly permeable gravel and sand soil. In the event of a leak, contaminants would rapidly seep into the groundwater, which lies just 40 feet below the surface. This groundwater feeds directly into Bear Creek and Summit Creek, which flow into the Dezadeash River—an important water source that winds through Kluane National Park and drains into the ocean. This contamination pathway endangers not only local ecosystems but also marine environments.
Proximity to Critical Natural Habitats: The proposed facility is located only 500 meters from Bear Creek and Snake Creek and within 2 kilometers of the park boundary. This area provides primary denning grounds for bears and moose, serves as a migratory route for bird species, and is the only known habitat for the endangered Draba flower. The risk of contamination would have far-reaching impacts on these species and the overall biodiversity of the region.
Lack of Consultation and Land Use Planning: This project is moving forward without community consultation or an established land use plan, despite Champagne and Aishihik First Nation (CAFN) previously declaring that no further development should occur in the area until a comprehensive land use plan is created. Local government employees have reported being instructed not to discuss the project, leaving the community without transparency or representation in the decision-making process.
Economic Impact: Real estate agents, lawyers, and financial institutions have warned that this project could reduce property values and hinder mortgage approvals for current and prospective residents. The risks associated with living near a contaminated soil treatment facility create an economic burden for the community.
Environmental and Health Risks Supported by Research
Research underscores the health and environmental risks of siting an LTF in high-wind, high-drainage areas:
Airborne Contaminants and Bioaerosols: Studies have shown that high winds can spread airborne contaminants over large areas, posing respiratory and ecological risks. Bioaerosols containing harmful microorganisms and heavy metals can be carried into residential areas and natural habitats, causing long-term environmental degradation.
Permeability of Gravel and Sand Soils: Due to the high permeability of gravel and sand, contaminants can rapidly enter groundwater systems. Unlike clay, which offers a natural barrier, gravelly soils allow for quick migration of hazardous substances, increasing the likelihood of contaminant spread.
Proposed Actions and Our Request for Support
While we recognize the need for a contaminated soil treatment facility, it must be in a suitable location that prioritizes environmental safety and community well-being. We request:An immediate halt to the current project to allow for a comprehensive review.Consideration of an alternative site with a clay-based foundation, located away from high-wind areas, residential communities, and critical water sources.Full transparency and meaningful engagement with local residents, CAFN, environmental experts, and stakeholders.
We urge you to lend its support in opposing this unsuitable project location and advocating for a more responsible alternative. The potential consequences to Kluane National Park, the Alsek Valley ecosystem, and our community are too serious to overlook.
