Résumé: This licence has been issued for the scientific research application No.5551. The overall objective of the research is to eventually determine the environmental chemistry of the elevated metal concentrations, which will in turn determine the environmental risk that these measured concentrations pose (i.e. will answer, at least in part, the questions: do these sites require remediation, and in w...

Résumé: This licence has been issued for the scientific research application No.4544. The objectives of this research are: 1) To investigate the environmental chemistry of the borrow pits and immediate surrounding areas to determine what, if any, environmental risk do the elevated concentrations represent; 2) To investigate the environmental chemistry of an undisturbed area around the Inuvik to Tukto...

Résumé: The purpose of the project is to work in collaboration with Northwest Territories (NWT) communities to collect water quality data to answer community concerns and questions about the health of NWT waters, to enhance understanding of cumulative impacts and to contribute to decision making. There are three associated objectives: 1) collect water quality data at locations throughout the NWT, to ...

Résumé: Climate change and industrial contaminants are two principal concerns for Arctic residents. The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater e...

Résumé: Long term goals of this research: 1. Identify and quantify the physical, chemical and ecological processes that affect contaminant transfer in Arctic aquatic food webs in response to observed and predicted Climate Variability & Change (CVC) in the Husky Lakes Watershed (HLW). 2. Provide people and regulators of Inuvik and Tuktoyaktuk with tools to effectively monitor selected highly valued compo...

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) select wastewater systems. Samples will be taken during the perio...

Résumé: Northward flowing rivers are thought to be major ways in which contaminants are introduced to the Arctic Ocean. As part of an on-going study, river water and sediments will be collected over the course of the year and assessed for the presence of contaminants. A total of 12 rivers in the Canadian arctic mainland will be sampled in this study, including the Mackenzie, Coppermine, Burnside, Ellice...

Résumé: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...
