Water Quality Index (WQI) of Canadian Environmental Sustainability Indicators (CESI)
Staff from all regions of Environment Canada’s Water Quality Monitoring and Surveillance Division met with representatives from the provinces (November 30 - December 1, Montreal), to discuss the Water Quality Index (WQI) and work together to improve it. Organized by Julie Boyer and Jean-François Bibeault, the workshop was an opportunity to present 2010 WQI results, statistics relevant to the WQI, as well as work on water quality and indicators. Among other presentations, Malcolm Conly, Prairie and Northern Region, presented the Peace-Athabasca Delta Ecological Monitoring Program; Paul Klawunn, Ontario Region, presented problems regarding the Niagara River; and Aaron Todd, Ontario Ministry of the Environment, shared the importance of monitoring chlorides and developing recommendations specific to the sites for this anion. This annual meeting also included an intensive session on the process for validating and checking scientific data, encouraging a discussion of the relevance of standardizing data quality assurance and control practices.
Canadian Council of Ministers of the Environment (CCME) Water Quality Monitoring Sub-Group Restarted
On November 30, Paul Klawunn (new sub-group co-chair), Chris Lochner and Jean-François Bibeault hosted an informal meeting to discuss restarting this dormant CCME sub-group. The meeting was held during the annual Canadian Environmental Sustainability Indicators (CESI) meeting in Montreal (see above), capitalizing on the attendance of many provincial and territorial water quality monitoring colleagues. The sub-group has been dormant since former EC chairs moved on, and re-initiation of the group was enthusiastically supported by all present. A follow-up teleconference has been planned to formalize the initiatives discussed at the meeting.
First National Canadian Aquatic Biomonitoring Network (CABIN) Science Forum, Vancouver, British Columbia
The 1st Canadian Aquatic Biomonitoring Network (CABIN) Science Forum was held in Vancouver late in 2010, bringing together users from a variety of sectors and backgrounds to enhance monitoring programs and national transfer of knowledge between CABIN pioneers and more recent users and partners. The Forum was a resounding success with 150 registered participants from all provinces, Yukon and Northwest Territories. Of the participants, 65% were CABIN users/partners and 35% were people interested in getting involved in CABIN. A webinar was offered on the first day, providing a cost-effective way to encourage participation from across the country, with 34% of participants using this approach. Proceedings will be made available in January and will include abstracts, as well as discussion of the successes and challenges of the program. See the CABIN website.
Lake Winnipeg Basin Initiative (LWBI) Presentation to Manitoba Environmental Industries Association
Nancy Hnatiuk, Manager of the Lake Winnipeg Basin Office, recently provided an overview and update on the LWBI to approximately 30 members of the Manitoba Environmental Industries Association (MEIA). MEIA is a non-profit organization that connects business, government and interested stakeholders with environmental issues and opportunities. Members include environmental technology and service companies, engineering and environmental consulting firms, government departments and crown corporations, law firms, businesses, research companies, associations and community organizations. Following the presentation, discussion topics included the application and future role of science, as well as the need for government action on nutrient management.
Urban Contaminant Study in Northern British Columbia
Dr. Ian Droppo took part in collaborative research meetings on an urban street dust sediment study for the city of Prince George, British Columbia, where a mix of industrial, commercial and residential land uses contribute to a spatially diverse distribution of sediment quality with possible management implications and health-related effects.
Well over 400 samples have been collected and are currently being analyzed for grain size distribution, mineralogy and metal concentrations (with sequential extraction) with the end results contributing to EC’s research mandate in urban water management.
Phosphorus in Canadian Aquatic Ecosystems
The first national assessment of nutrient concentrations in Canadian watersheds was completed using data taken from water quality monitoring sites operated by Environment Canada and sites operated jointly by Environment Canada and federal, provincial and territorial partners. The web content provides an initial synthesis of the state of (2004-2006), and trends in (1990-2006), nutrients in Canada’s watersheds, as a complement to the water quality index (Canadian Environmental Sustainability Indicators). A more detailed report on the situation of all nutrients measured in the watersheds will follow. In summary, elevated concentrations of total phosphorus were measured in some regions of Canada, with close to one-third of assessed sites classified as eutrophic or hypereutrophic. For more information, see the Fresh Water Quality Monitoring website.
Funding to Investigate Innovative Wastewater Disinfection
Ian Droppo, Peter Seto, Cheng He and John Gibson, with researchers from Queen’s University, the University of Toronto, Trojan Technologies, and the Ontario Ministry of the Environment, were successful in obtaining a 4-year funded NSERC Collaborative Research and Development Grant to investigate the relationship between physico-chemical-microbial structure and UV disinfection of biological flocs in municipal wastewater. Much of the investigative study will take place within the Wastewater Technology Centre of Environment Canada and will include graduate students from the universities working on-site and co-supervised by EC staff. This research is expected to lead to development of an innovative, more cost-effective technology for wastewater disinfection. It is also thought this technology may also enhance the opportunity for wastewater reuse initiatives.
Canada-U.S. Technical Working Group on Viruses in Wastewater
Health Canada hosted a meeting in Ottawa that brought together scientists and technical program staff from the U.S. Food and Drug Administration (U.S. FDA), Health Canada, the Canadian Food Inspection Agency (CFIA) and Environment Canada to discuss issues related to the survivability of viruses in municipal wastewater effluent. The focus was on viruses that pose public health risks from food-borne illnesses resulting from consumption of bivalve molluscan shellfish from marine waters potentially impacted by sanitary sewage. Studies conducted in both Canada and the U.S. were presented and technical discussions were held on analytical methods, wastewater treatment methods to address virus reduction, and acceptable dilution ratios to reduce risk.
At this meeting, the U.S. FDA tabled the initial draft of their Supplemental Report of the Audit of Wastewater Treatment Plant (WWTP) and Prohibitive Zone Classifications. This is the long-awaited second report stemming from the U.S. FDA's audit of the Canadian Shellfish Sanitation Program (CSSP) conducted in 2009 in Atlantic and Pacific regions, although the first draft focuses almost exclusively on WWTPs in Atlantic Canada. A second draft, to be received in the coming weeks, will include findings from the audit in British Columbia. Initial findings are positive, but suggest that there are a few outstanding technical and policy issues to be addressed, related to the classification of shellfish growing areas adjacent to WWTPs. Some of these technical issues will be incorporated into the work of the Canada-U.S. Working Group, and the CSSP agencies (CFIA, EC and Fisheries and Oceans Canada) will respond accordingly to the science results to make any necessary changes to program policy.
New Funding from the Canadian Space Agency
Caren Binding and Robert Bukata have been awarded $127K over two years from the Canadian Space Agency under their Government Related Initiative Program to further develop and promote the operational use of remote sensing in EC water quality research and monitoring activities. Several decades of research and development in aquatic optics and remote sensing have culminated in the ability to produce, in near real time, water quality products from earth-orbiting aquatic colour satellite sensors such as NASA’s MODIS and the European Space Agency’s MERIS. These products are providing prompt and detailed observations of, for example, the development and progression of algal blooms in Lake of the Woods, and have been used to monitor inter-annual trends and spatial variability of coloured water quality parameters within the Great Lakes.
Groundwater Contamination - FCSAP Technical Expert Support Meeting
Greg Bickerton presented Groundwater Contamination Discharging to Surface Water & Associated Ecological Effects: Update on NWRI Research Activities as an invited speaker at the Technical Expert Support Meeting organized by the FCSAP (Federal Contaminated Sites Action Plan) Secretariat held in Ottawa. The presentation highlighted several active projects that examine groundwater contamination discharging to surface water ecosystems (led by Jim Roy and Greg Bickerton) and the potential use of artificial sweeteners as groundwater tracers of human wastewater effects (led by Dale Van Stempvoort). Recent and future investigations (with research scientists Lee Grapentine and Patty Gillis) of the ecological effects of contaminated groundwater on benthic ecosystems were also discussed. This inaugural meeting was attended by technical staff from all Environment Canada regions and presentations were provided by specialists from various federal departments and academia.
ISO Accreditations for Environment Canada Laboratories
The Quality Management Systems (QMS) used in EC's Newfoundland and New Brunswick microbiology laboratories were evaluated in September and October by the Canadian Association for Laboratory Accreditation (CALA). These evaluations completed the ISO 17025 accreditation and initial year evaluation cycle of all EC-owned and operated microbiology laboratories in Eastern and Western Canada and demonstrated that the QMS developed by the national Marine Water Quality Monitoring Laboratory Management Team was sound and providing a high level of quality control and quality assurance for the large number of marine water samples processed annually.
These samples are collected and analyzed to support evaluation of environmental conditions in bivalve molluscan shellfish growing areas and meet Environment Canada's responsibilities under the Canadian Shellfish Sanitation Program.
In October 2010, the ISO/IEC 17025 accreditation of the Quebec Laboratory for Environmental Testing (QLET) was renewed for a two-year period by CALA. This year, the scope of accreditation was broadened with the addition of three inorganic chemistry parameters: ammonia nitrogen, major ions by ion chromatography and ultra-trace mercury by cold vapour fluorescence spectroscopy. This accreditation provides the QLET Ultra-Trace Mercury Analysis Laboratory Centre of Excellence with external recognition of the laboratory's high-quality work in a very specialized field. Once again, QLET is proud to be recognized for its skill and innovation. This recognition bolsters the reputation of Environment Canada's services and leads clients to trust in their quality.
