Removing Antibiotics from Wastewaters – A Research Collaboration with Queen’s University

Kirsten Exall and Vimal Balakrishnan are collaborating with colleagues at Queen’s University in Kingston, Ontario, on a study of Micellar Enhanced Ultrafiltration for the removal of sulfonamide antibiotics from wastewaters. The study uses nuclear magnetic resonance (NMR) and related techniques to examine the interactions of sulfonamides with micelles and improve understanding of factors that influence the efficiency of the removal process. Following a recent meeting, Drs. Exall and Balakrishnan had the opportunity to tour the new facilities of GreenCentre Canada, a national Centre of Excellence for Commercialization and Research. The not-for-profit centre provides a state-of-the-art facility to develop Green Chemistry discoveries and assist with technology transfer, product development and commercialization. Green Chemistry focuses on design and application of chemical products and processes that eliminate or minimize damage to the environment while reducing waste and energy consumption. While the current focus is primarily on bringing together academic researchers and industry, the GreenCentre is also interested in facilitating collaborations involving science-based government departments and assisting with technology transfer.

Peace-Athabasca Delta – Environmental Monitoring Program

The Peace-Athabasca Delta – Environmental Monitoring Program (PAD-EMP) Steering Committee, facilitated by Parks Canada, has participation from ten First Nations communities, two ENGOs (World Wildlife Fund and Ducks Unlimited), Environment Canada, Indian and Northern Affairs Canada, the Department of Fisheries and Oceans, the Province of Alberta and the Government of the Northwest Territories. Given the influence of upstream and regional industrial development (e.g., oil sands, hydro power) and climate change, the PAD-EMP is in the process of designing a comprehensive ecological monitoring program to support effective environmental stewardship by providing long-term data and information to evaluate and report on the Delta’s ecological integrity. The design of the monitoring program will incorporate the most current and best understanding of both western science and traditional ecological knowledge. A "State of Vulnerability" report for the PAD will be written as a precursor to finalizing an ecological monitoring program.

International Lake of the Woods and Rainy River Watershed Task Force

In response to local concerns regarding water quality and management issues in the Lake of the Woods and the Rainy River watershed, the governments of Canada and the United States requested that the International Joint Commission (IJC) review and make recommendations on the bi-national management of the watershed and the potential role of the IJC in this management. The International Lake of the Woods and Rainy River Watershed Task Force was appointed by the IJC to assist it in this task. Melanie Neilson, Water Quality Monitoring and Surveillance-Ontario, has been appointed as the Canadian Co-Chair of the Task Force, and Gail Faveri, Boundary Water Issues, as a member.

Since receiving its mandate on July 13, the Task Force has been extremely active holding numerous meetings and conference calls, drafting a work plan and a citizen engagement plan, and meeting with existing IJC Boards. As directed by the IJC, the Task Force will have a strong focus on outreach and engagement with the public, government agencies and First Nations. To this end, extensive public consultations are to take place in the watershed throughout the next year and a Citizens Advisory Group is being established. The final report of the Task Force to the IJC is due July 15, 2011. 

Ottawa River Summit 2010

Myriam Rondeau, principal specialist in fluvial geochemistry of the Quebec Fresh Water Quality Monitoring team, attended the first Ottawa River Summit, held in Gatineau. Organized by Ottawa Riverkeeper and the National Capital Commission, the Meeting brought together some 70 attendees from municipalities and First Nations communities, as well as other delegates such as those from watershed organizations. The meeting was intended as a first step towards adopting a common vision and a plan to protect the Ottawa River. During the day, a number of participants talked about positive achievements that protect the Ottawa River throughout its watershed. Their presentations furthered the sharing of information and opened the way for future collaborations. Since 2004, the Quebec Fresh Water Quality Monitoring team has been operating a water sampling station at the mouth of the Ottawa River at Carillon.

Canadian Aquatic Biomonitoring Network (CABIN) Field Certification Course - Kakisa Lake, Northwest Territories

Dehcho participants practicing kick sampling during the Canadian Aquatic Biomonitoring Network field certification course | Photo: Environment Canada  A three-day CABIN field certification course was provided to Dehcho community members on and around the shores of Kakisa Lake in late August. This program was delivered in partnership with the Dehcho First Nations’ Aboriginal Aquatic Resources and Oceans Management Program (AAROM) and partially funded by Environment Canada (EC) using International Polar Year (IPY) resources. Classroom-based training activities were delivered at the Kakisa Lake band council office and three unique field training sites were selected for hands-on demonstration and training purposes. The CABIN training was led by Nancy Glozier and Sarah Hall with additional support provided from EC’s Yellowknife biologists Kerry Pippy and Annie Levasseur. Staff and learners were given on-site accommodations supported by the Dehcho First Nations, which further supported the successful delivery of the content and facilitated development of a strong rapport between instructors and participants. As a result, the ability to cooperate with local First Nations communities to conduct CABIN monitoring in the Northwest Territories has been greatly enhanced.
