Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2006 2005
Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2003
Summary: In the Mackenzie Delta region, many of the drilling mud sumps constructed in the 1970s have partially or completely collapsed. The collapse of a sump can release contaminants previously immobilized in permafrost. The long-term degradation of many sumps...

Principal Investigator: Dyke, Larry
Licensed Year(s): 1998 1997
Summary: Field work this year will be devoted to 1) determining the maximum extent of potassium chloride migration from sumps examined in 1997, 2) examine the Mallik L-38 sump constructed in 1972 as one of the oldest sumps in the Delta, 3) examine the sumps in Parsons Lake area where topographic relief has added the potential for salt migration due to groundwater flow. Sumps along Kumak Channel, near the m...

Principal Investigator: Reimer, Kenneth J.
Licensed Year(s): 1997
Summary: The Environmental Services Group has been requested by Defence Construction Canada and DCLU, to continue conducting environmental investigations of former DEW Line sites. Personnel will collect soil, sediment, plant, water, paintchips and insulation samples from areas of suspected or known contamination. The samples will be analyzed for inorganic elements and PCB's. In addition a small-scale bio...

Principal Investigator: Falkner, Kelly K.
Licensed Year(s): 1994
Summary: The researchers will be tracking the fate of Mackenzie River waters through the Delta and into the Arctic Ocean by using natural geochemical markers. Water samples will be collected by drilling through the ice at 50 locations along the main channel of the river and out over the shelf. This information is important for understanding the circulation of Arctic Ocean waters, the processes of global ...

Principal Investigator: Jasper, Jesse
Licensed Year(s): 1993
Summary: The researchers will work in collaboration with other scientists to study water and sediment characteristics at certain Inland Water Directorate sites in the Mackenzie Delta. This study will be useful for evaluating impacts of hydrocarbon development as well as delta flooding on water flow, wildlife and vegetation in the delta. In addition, contaminants in water and sediments will be measured....

Principal Investigator: Washuta, A.S.
Licensed Year(s): 1993 1992
Summary: The information gathered at the ten NWT DEW Line Sites will be used to prepare detailed Contract Documents for each site's environmental clean up. During the site visits, the researchers will conduct overall site surveys and identify areas or structures requiring either clean up or demolition. The sites to be visited are Nicholson Pen., Clinton Pt., Cp. Young, Byron Bay, Jenny Lind Isl., Gladman...

Principal Investigator: Swyripa, Murray
Licensed Year(s): 1993
Summary: 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...

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: 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 ...

Principal Investigator: Smith, Daniel W.
Licensed Year(s): 1979
Summary: To sample treated and untreated domestic water supplies for physical and chemical analysis, (e.g. turbidity, color, temperature and trace elements analysis, e.g. lead, zinc, silver and cadmium)....
