Water Quality Monitoring on Tributaries in the Athabasca River Oil Sands Region

Ells River (EL1, ELLS RIFF 2, ELLS RIFF5 [2012-2015])
Mackay River (MA1 [2012-2015], MA2 [2013-2015])
Steepbank River (STB RIFF1, STB WSC, STB RIFF7, STB RIFF10 [2012-2015])
Firebag River (FI1, FI WSC [2012-2015])
Muskeg River (MU1 [2012-2015]), MU6 [2012-2015]), MU7 [2012])
High Hills River (HIHI1 [2013-2015])

Water quality of tributaries in the Athabasca River oil sands region is heavily influenced by the presence of the underlying Cretaceous bedrock, which is comprised of shale, sandstone and limestone. The waters are moderately hard (average alkalinity of 114 mg l-1 CaCO3) because of their mineral content, particularly magnesium (average 8.62 mg l-1), calcium (average 28.06 mg l-1) and bicarbonate (138.53 mg l-1). This mineral content results in an average conductivity of 245 +/- 4 µS cm-1 and total dissolved solids concentration of 140 +/- 2 ppm. Concentrations of nitrogen and phosphorus (indicators of nutrient status) are typically low to moderate, averaging 0.14 mg l-1 total phosphorus, 0.03 mg l-1 total dissolved phosphorus, 0.92 mg l-1 total nitrogen, 0.09 mg l-1 nitrogen as nitrate+nitrite, and 0.04 mg l-1 nitrogen as total ammonia.

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.

Oil Sands Sediment Exposures of Embryo-larval Fathead Minnows

Dataset contains laboratory-studied fathead minnow egg and larval survival rates when exposed to sediments collected from 18 sites in the Athabasca watershed (2010-2014). A controlled laboratory study examined the impacts on fathead minnow eggs and larval development when exposed to collected sediments at concentrations of 1, 5 and/or 25 g/L. Sediments and water were renewed daily, and eggs were assessed as they hatched (in about 5 days), and as the larval fish grew to 8-9 days post hatch (dph), and 15-16 dph. The data in the file present the mean survival (and standard deviation).

The river bed sediments in the Lower Athabasca are known to shift and migrate downstream. Numerical modelling of water quantity and quality (including sediments) requires accurate river channel cross-sectional geometry within the area of study. Such cross-sectional geometry prior to 2012 was limited for the Lower Athabasca River restricting modelling accuracy and efficiency. As such, in order to better understand the bed sediment dynamics of the lower Athabasca River and to support model development (e.g., calibration/validation of sediment/bitumen erosion/transport/deposition), high resolution swath bathymetry data were collected form bank to bank during open water seasons (2012-2014) covering approximately 115 km from Fort McMurray to the mouth of the Firebag River.

This data set provides pesticide sample analyses results for stream sediment samples for the province’s Pesticide Monitoring Program. The sampling includes sampling a total of nine rivers across PEI, with three of the rivers being sampled each year. Sediment samples are collected once in July, twice in August (once during a normal/dry weather and once during wet weather), and once in September. The two samples in July and September are collected during dry weather.

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.

Mainstem Athabasca River Biomonitoring

Benthic macroinvertebrates, comprising insects, crusteaceans, molluscs and worms, represent a group of organisms used widely in environmental monitoring programs as early warning indicators to assess the effects of change in water quality or physical habitat conditions on aquatic ecosystem health. An interpretive report (Culp et. al., 2018) was released in 2018 which included assessments of the benthic and supporting data from 2012-2015. An excerpt from the executive summary regarding the mainstem benthic invertebrate results is provided below and the full report can be found online at https://open.alberta.ca/publications/9781460140314).

The Great Lakes Sediment Database (also known as the National Water Research Institute (NWRI) Sediment Archive) is an archive of data on the sediments of the Great Lakes, their connecting channels, and the St. Lawrence River which was collected by NWRI and in cooperation with other agencies between 1960 and 1975. It is housed in Environment and Climate Change Canada's Canada Centre for Inland Waters in Burlington, Ontario. The data has been subdivided into two groups according to location and purpose:

1.Great Lakes Basin Sediment Data: physical and geochemical data for sediment samples and cores collected lakewide in lakes Ontario, Erie, St. Clair, Huron (including Georgian Bay), Michigan and Superior between 1960 and 1975 by R.L. Thomas, A.L.W.

Shallow groundwater and the interaction of these waters with surface water in the mineable area of the Athabasca oil sands region are being examined to assess the role and importance of groundwater in the regional river ecosystems. Groundwater quality chemistry data is available from 182 shallow groundwater samples collected below the Athabasca, Ells, Muskeg and Steepbank rivers and 2 monitoring wells near an existing tailings impoundment. Additionally 5 surface water samples were also collected for comparative purposes. All samples were collected between 2009 and 2011 and include analyses for up to 60 parameters, including electrical conductivity, pH, temperature, and dissolved oxygen concentration, major ions, trace metals, total concentrations of naphthenic acids, fluorescence intensity using synchronous fluorescence spectroscopy (SFS) and others.
