Monitoring activities have collected bulk suspended sediment samples using continuous flow centrifuges and Phillips Tube samplers in the Lower Athabasca River and tributaries respectively. Further, in the absence of pre-development monitoring for this region, high fidelity dated lake sediment cores were used to assess the natural range in contaminant deposition to this region and to obtain a historical perspective of contaminant loadings. All sediments (suspended river and lake cores) have been analyzed in the laboratory for sediment quality variables as per Appendix B in the Integrated Monitoring Plan (cores were also analyzed for paleo indicators of ecosystem health such as diatoms). In addition, as the Lower Athabasca river bed sediments are known to shift and migrate downstream, bathymetric maps of the bed-channel morphology over time was also completed.
Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In partnership with the provinces, territories and other agencies, WSC operates over 2500 active hydrometric gauges across the country, maintains an archive of historical information for over 7600 stations and provides access to near real-time (water level and stream flow) provisional data at over 1700 locations in Canada. Monitoring activities are underway to collect suspended sediment samples in the Lower Athabasca River.
Provides public access to archived sediment data daily loads, daily concentration, instantaneous concentration for stations of interest using search criteria. The sediment monitoring program discontinued in 1989. Archived sediment data are disseminated both online and offline via MS Access file.
This data set demonstrates some variation in the data parameters, both in time and with distance along the mainstem Athabasca and two tributaries (Ells and Steepbank Rivers). For the mainstem Athabasca (bulk suspended sediment samples collected via continuous flow centrifugation), these variations are not considered unusual for a dynamic mobile bed river. For the Ells and Steepbank Rivers (bulk suspended sediment samples collected via long-term time-integrated Phillips Tube samplers), however, some spatial and temporal trends were evident. Eight polycyclic aromatic hydrocarbon parameters for the Ells River and thirteen for the Steepbank River showed increasing trends as you move downstream (for periods where samples were collected at multiple sites).
Monthly estimates of drug metabolites in wastewater in select Canadian cities, by type of drug, presented as load per capita. The 95% confidence interval, standard error, and imputation rate of the load per capita are included as well as the detection rate of the drug metabolites in wastewater.
The Great Lakes Basin Integrated Nutrient Dataset compiles and standardizes phosphorus, nitrogen, and suspended solids data collected between the 2000-2019 water years from multiple Canadian and American sources around the Great Lakes. Ultimately, the goal is to enable regional nutrient data analysis within the Great Lakes Basin. This data is not directly used in the Water Quality Monitoring and Surveillance Division tributary load calculations. Data processing steps include standardizing data column and nutrient names, date-time conversion to Universal Time Coordinates, normalizing concentration units to milligram per liter, and reporting all phosphorus and nitrogen compounds 'as phosphorus' or 'as nitrogen'.
Placer mining involves washing stream gravel to separate and save free gold particles. Usually a placer mine must discharge excess effluent water, which contains some residual suspended fine silt and clay particles, from a settling pond, back into the stream. This study examines the applicability of introducing placer effluent through a diffuser to lessen environmental impact. A diffuser is a mechanism which introduces effluent fluid into the main current of a receiving stream so that mixing and dispersion are facilitated.
The Agri-Environmental Indicator Risk of Water Contamination by Coliforms provides two variables including the Soil Coliform Load and the Coliform Risk to Water. The Soil Coliform Load indicator is the estimated accumulation of coliforms on the soil and the Coliform Risk to Water indicator is the relative risk of coliforms getting into the waterways.
Products in this data series present results for predefined areas as defined by the Soil Landscapes of Canada (SLC v.3.2) data series, uniquely identified by SOILLANDSCAPEID values.
Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment quality objectives and identify emerging issues are included in this dataset. The Great Lakes are joined together by river systems known collectively as connecting channels, including the St. Marys River, the St. Clair River (and Lake St. Clair), the Detroit River, the Niagara River, and the St. Lawrence River. Uniquely, the connecting channels originate from the outflow of one or more large, oligotrophic lakes rather than the accumulation of a network of tributaries.
This Alberta Official Statistic describes the Full Load Equivalent (FLE) by each institution and academic year within Alberta's Publicly Funded Post-Secondary Education System. FLE is a measure used so that we can make comparable calculations across different institutions, across different programs. The FLE is measured by taking the load of the student enrolled (instructional hours + practicum hours) and dividing by the full load of that program. This results in a comparable metric to be able to use across the system.
