These projects mostly use bird species diversity and population performance as indicators of ecosystem health. In part using student energies, data bases are maintained tracking key demographic parameters of important focal species. Some of these…

The objective of this study is therefore to evaluate the impact of freeze-thaw cycles on oxygen migration within saturated covers over tailings, by simulating a tailings cover system in the laboratory through column experiments. Covers for waste…

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…

"The following report endeavours to evaluate the technical and economic feasibility of utilizing the waste heat from a 500 KWe bioenergy gasification plant in the Haines Junction area and, when possible, the secondary option of using heat from…

[T]his report explores a hybrid-applied solution: the use of saturated covers, which involve lifting an elevated water table into a tailing impoundment that maintains saturation within the tailing profile without allowing excess water directly along…

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…

The purpose of this document is to report the results of the Bioremediation Project conducted by the Industrial Research Chair in Mine Life Cycle at Yukon College, between February 2013 to January 2014, to the industrial partners Alexco Resource…

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…

Passive treatment systems (PTS) present a potential low-cost solution to treating mine-impacted waters (MIW) and impeding release of contaminants, such as metals and sulphate, into receiving waters in remote mine sites in Yukon. Nevertheless, the…

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…

"Northern Canadian communities are at the forefront of climate change. Permafrost thaw is one of the major threats that they face. Many communities, particularly those within the discontinuous permafrost zone, have ground temperatures just…

Throughout northern Canada, a variety of documents speaking to climate change adaptation have been published. These range from peer review articles over presentations, websites, and reports to online tools. This project represents an effort to tie…

In situ immobilization of metals using soil amendment processes is increasingly being considered as an effective and low cost remediation alternative (Mench et al. 2007, Kumpiene et al. 2008, Fellet et al. 2011). Leonardite is a carbon-rich material…

Four (4) pilot anaerobic bioreactors were commissioned at the Minto mine site in the summer of 2014 by Amelie Janin, NSERC Industrial Research Chair at Yukon College, and Capstone staff. Installation was completed on August 7th, 2014 and operation…
