Passive biological treatments have been proposed as an efficient and cost effective treatment of metal bearing water discharged from mine sites after closure. However, concerns are typically expressed around biological treatments and their…

Coupling energy storage systems with renewable generation systems has a variety of advantages including: increasing the penetration of renewables, reducing curtailment, providing energy security, lowering greenhouse gas emissions and providing an…

The objective of this project was to identify landscape hazards in Pelly Crossing and nearby surroundings by compiling geoscience data from various field studies and scientific reviews (i.e., surficial geology and hydrology). This data was used to…

Declines in American Kestrel (Falco sparverius) populations are widely reported, and Breeding Bird Survey (BBS) data suggest that the North American population declined significantly from 1984 to 2007. Potential factors include the spread of West…

The goal of Yukon Passive Water Treatment Workshop was to foster discussions between mines environmental personnel, regulators, project managers, consultants, design engineers, and other affected stakeholders to identify the gaps that need to be…

The overall goal of this project was to assess, in three stages, the use of fish otolith microchemistry as a potentially new monitoring tool to be applied around Yukon mine sites. High quality environmental assessments are critical to sound land and…

This report presents the results of a project that aims to understand and, if possible, recommend actions to remediate the issues caused by the formation of sinkholes at km 82 and km 102-103 of the Dempster Highway. At km 82, this has resulted in…

Climate change is a significant challenge for northern communities, where the impacts of a warming climate are already having considerable effects (Huntington and Weller, 2005). Many people living in small, isolated communities in northern Yukon are…

The revegetation needs in the Yukon are projected to grow in the next few years as new mining projects go through the environmental assessment process, and plans for the revegetation of large-scale abandoned mines begin to take shape. Revegetation…

In this review, we evaluate the challenges encountered and the adaptations required for the successful treatment of mine-impacted waters in cold climates with Passive Treatment Systems (PTSs). Engineered PTSs are modeled on natural wetlands, which…

Passive treatment systems offer a low cost and low maintenance means of remediating water contaminated by a variety of industrial and domestic factors. Natural wetlands demonstrate an innate ability to remove contaminants derived from mining/…

As passive water treatment technologies are increasingly being considered as a part of mine site closure in Yukon, it is important for industry to share with the government the questions they have, and vice versa. Efforts are currently underway by…

Climate change is a significant challenge for northern communities, where the impacts of a warming climate are already having considerable effects (Huntington and Weller, 2005). Many people living in small, isolated communities in northern Yukon are…

The Northern Mine Remediation project began with the formation of the Yukon Mining Research Committee (YMRC) in 2012. As representatives of the mining industry they wanted to create a platform for industry, Yukon College, First Nations, and…

Constructed wetlands (CWs) have been employed as passive treatment systems for metal contaminated mine drainage in Canada. However, relatively few CWs have been documented in northern environments and further studies are needed to understand the…
