Summary: This licence has been issued for the scientific research application No.4988. The objectives of this project are to determine: 1) From the outer Slave River Delta (SRD) (river-water dominated) to the apex of the SRD (runoff dominated), what the current status of nutrients and contaminants in SRD wetland ecosystems are; 2) How trace elements (e.g., mercury) move through SRD wetland food webs; an...

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 lagoon and wetland system in the communities where the r...

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...

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...
