Fate of heavy metals in lagoon and wetland wastewater treatment systems and quantification of relative impacts to downstream aquatic systems
Principal Investigator: Jamieson, Rob
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4511. The overall objective of this study is improved understanding of heavy metals in Sewage Disposal Facilities (SDFs) and Solid Waste Disposal Facilities (SWDFs) in the NWT. The proposed study aims to answer the following questions: 1) What is the existing treatment capacity of SDFs in NWT for heavy metals? 2) Are SDFs “...


Developing New Tools for Assessing Legacy Pollutants and their Ecological Consequences in Lakes Near Northwest Territories Mines
Principal Investigator: Blais, Jules M
Licensed Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...


Gordon Lake Assessment Project
Principal Investigator: Doucet, Michael
Licensed Year(s): 2016 2015
Summary: The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake and potentially six Gordon Lake south sites. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials. In addition, samples of biota (includin...


2005 Aquatic Efects Monitoring Program
Principal Investigator: Wytrychowski, Scott I
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The purpose of the 2005 Aquatic Effects Monitoring Program is to initiate a long-term aquatics sampling program in order to produce a data set that will be used in trend analyses to track the overall effects of the project on the aquatic ecosystem of Lac de Gras and to confirm predictions made during the Environmental Assessment. This is achieved by conducting consistent annual sampling at fixed m...


Mercury Concentration of Two Lakes on the Yellowknife River System Affected by the Bluefish Hydrodam
Principal Investigator: Puznicki, Wayne
Licensed Year(s): 1997
Summary: The objective of the study is to assess the concentration of mercury in fish, water and sediment in Bluefish and Duncan Lakes; to provide information to the Yellowknives Dene First Nation to make decisions relating to the use of fish and water from these lakes; and to correlate traditional knowledge with scientific data. Bluefish & Duncan Lakes are about 50 km to the northeast of Yellowknife. Tr...
