Arctic Wastewater Research
chercheur principal: Challen Urbanic, Jane
Année(s) de permis: 2012 2011 2010 2009
Résumé: The objective of this research is to assess the performance of lagoons and wetlands in the treatment of municipal wastewater in Canada's Arctic. A secondary objective is to determine the occurrence of trace contaminants in northern wastewaters. Samples will be taken from the influent (raw sewage) and effluent (treated wastewater) of each lagoon and wetland system in the communities where the r...


Arsenic sequestering by microbial activity in wetlands adjacent to the Terra Mine tailings lake, Northwest Territories
chercheur principal: Drysdale, Jessica A
Année(s) de permis: 2009
Résumé: The objective of this study is to identify how arsenic is bound in the sediments, and determine the role of microbial activity in arsenic mobility. It is anticipated that the results of this research will benefit the design of a constructed wetland, which is expected to be part of site remediation. The researchers propose to sample sediments and surface and pore water from the Ho-Hum Lake wetla...


Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
chercheur principal: Nicholson, Barbara
Année(s) de permis: 1992
Résumé: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...
