Summary: 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 wastewater system identified earlier in the application. ...

Summary: This project aims to address a local concern about the release of contaminants resulting from an enduring fire at the Inuvik dumpsite by complementing the monitoring of Inuvik’s dumpsite for non-standard contaminants, and by reaffirming the drainage pathways from the dumpsite. Water samples (40-80 l) will be collected from two streams that clear the melt water from the dumpsite area, and the t...

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...

Summary: The Sewage Discharge Assessment will be carried out to meet the needs of the Hamlet of Tuktoyaktuk's water licensing requirements as issued by the NWT Water Board. The objective of the Sewage Discharge Assessment is to evaluate the potential impacts of sewage discharges on fish and benthos in the receiving environment by comparing reference and effluent exposed communities. Water, sediment and ...

Principal Investigator: Dyke, Larry

Summary: This project is intended to determine the amount by which fluids disposed of in abandoned oil well drilling mud disposal pits (sumps) have migrated into surrounding frozen ground. The sumps are not presently considered to pose any kind of environmental hazard but they do offer a unique opportunity to determine the effectiveness of permafrost as a containment for waste fluids. The main activity i...

Principal Investigator: Fehr, Alan
Licensed Year(s): 1995
Summary: The researchers will determine what impact sewage effluent from the Hamlet of Aklavik is having on the water quality and biota downstream. A literature review on the entire Delta will be completed. Interview with people having camps on the Delta and field observations will give an idea of past and present distribution of wood frogs. Water quality samples will be taken and wetland biota describe...

Principal Investigator: Den Dulk, Jan
Licensed Year(s): 1994
Summary: The researcher will conduct hydrogeological research in an attempt to determine the fate of sewage infiltration from the containment lagoon in Igloolik. Standard hydrogeological measurements will be taken to determine the quality (and hopefully the quantity) of the subsurface flow. This may include taking water samples for analysis (nutrients and bacteria) at the University of Guelph....

Principal Investigator: McNaughton, Duane
Licensed Year(s): 1992
Summary: The researcher will drill and complete some 20 observation wells in the vicinity of the Fort Resolution sewage infiltration pit. Sample groundwater and analyze it for sewage derived contaminants and coliform bacteria. A report will be prepared with recommendations based on the findings and submitted to relevant agencies in the N.W.T....
