Summary: The purpose of the Phase II ESAs is to further determine the current environmental and physical conditions at 10 sites along the Canol Trail and to reduce data gaps and allow development of the appropriate remediation strategies and costs. This will include the identification and quantification of environmental impacts to soil, sediment, surface water and groundwater, as well as the identificatio...

Summary: The objective of the work is to assist INAC with its ongoing work to clean up the abandoned mine sites, and to insure that remediation efforts are performing as planned. SENES will be carrying out the sampling for the Contaminants and Remediation Directorate (CARD) of Indian and Northern Affairs Canada (INAC). INAC CARD has the responsibility to manage the abandoned Great Bear Lake mine sites i...

Summary: 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...

Principal Investigator: Sealey, Heather N
Licensed Year(s): 2009
Summary: Arsenic was introduced to Ho-Hum Lake when it was used as a tailings pond during mining activities at Terra Mine, of the Silver Bear Mines Group. The objective of this study is to determine how arsenic is being removed from the lake water by a wetlands area. The intention for collecting data will include water and sediment sampling in Ho-Hum Lake, Moose Bay, and the wetlands between them. Seq...

Licensed Year(s): 2008
Summary: The overall objective of the program is to reduce liability of the Canol Trail by developing and implementing a remediation and/or risk management plan to mitigate existing or potential risks to human health and the environment from the trail. The primary focus will be on developing a logistics plan and inventorying materials, risks and hazards along the site for future assessments. The rese...

Principal Investigator: Livingstone, Stephen
Licensed Year(s): 2008
Summary: This license has been issued for the scientific research application #856. This research will collect environmental samples, and quantify and categorize waste materials left at the Sawmill Bay site in preparation for site remediation. Research will involve sediment, surface water, soil, and groundwater sampling. A detailed explanation of the research methodology can be found in the research a...

Principal Investigator: Fraikin, Chris
Licensed Year(s): 2005 2004
Summary: A field dye tracer study will be conducted to examine the mixing and dispersion characteristics of discharges from Imperial Oil, Norman Wells, to the Mackenzie River. This will be accomplished by injecting dye at the water release point under normal discharge conditions and measuring dye concentration at several river transects downstream of the discharge. The concentration profile at these tran...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...

Licensed Year(s): 2007 2006 2005 2004
Summary: This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...

Principal Investigator: MacNeill, Scott W
Licensed Year(s): 2003
Summary: This 5-day sampling program will involve fisheries, aquatic, and vegetation studies at/in the vicinity of the abandoned Port Radium Mine site. Concentrations of five biologically significant metals (antimony, arsenic, lead, nickel and zinc) will be dete...
