Oil Sands Environmental Management Bibliography

The Cumulative Environmental Management Association (CEMA)partnered with the Oil Sands Research and Information Network (OSRIN) to create the new Oil Sands Environmental Management Bibliography, which includes documents relevant to the environmental management of oil sands development in Alberta. The majority of the documents focus on the mineable oil sands in the Athabasca deposit, though some documents relate to in-situ developments. This bibliography was last updated in November 2014.

Water quality issues associated with composite tailings (CT) technology for managing oil sands tailings

Year of Publication: 2001

Abstract:
In the oil sands industry, composite tails (CT) is a tailings management approach in which the fines or clay fraction of extraction tailings are mixed with the coarse sand fractions, such that, with the addition of a coagulant aid, a non-segregating deposit is produced. Various coagulant aids have been shown to be effective. In the process of coagulation, the fine solids aggregate. Under self-weight consolidation (aided by high proportion of sand grains), particle-free water is released from the deposit leaving the fines solids and some water trapped within the voids of the coarse solids matrix. The rate and degree of water release determines when the resulting deposit can be classed as a “dry” landscape for reclamation. The coagulation of the clays has been demonstrated with a variety of chemicals, both organic and inorganic. Depending on the particular coagulant aid, various changes in pH, salinity, cation and anion levels, buffering capacity and toxicity have been observed. The impacts of some of these coagulant aids on water quality are described and the potential influence of the CT release waters on operational aspects of oil sands operations and on eventual reclamation options are discussed.

Water quality issues in the oil sands region of the lower Athabasca River, Alberta

Year of Publication: 2013

Abstract:
I summarize the controversies about industrial pollutants in freshwaters near the oil sands industrial area of Alberta, the inadequacies in environmental monitoring that have led to widespread misconceptions, and recent attempts to correct the problems. Adequate data are available to show that mercury, other trace metals, and polycyclic aromatic compounds are being added by industry to the Athabasca river system and its watershed, although the relative contributions of industrial development and natural sources remain in question. Recent improvements in water monitoring by Environment Canada show promise of resolving the controversies, although independent governance for Canada's and Alberta's water monitoring programs in the lower Athabasca River will be necessary to rebuild public confidence in the data and their interpretation by government and industry. I document one success story in the Athabasca River: the elimination of dioxins from pulp mills in the mid-1990s has caused a consumption advisory for fish in the river to be repealed.

Water quality of the Athabasca oil sands area. Volume 1: Data collection and quality

Authors Akena, A. M.
Year of Publication: 1980

Abstract:
This report documents locations of Athabasca Oil Sands area water quality sampling sites; sampling, analytical and quality control methods used; the volume and availability of assembled data; and an extensive appraisal of the quality of the data base. The quality control measures taken proved to be very useful in identifying causes of variations in analytical data and, as far as this water quality data base is concerned, in producing valid and accurate data.

Water quality of the Athabasca oil sands area. Volume IV: An interim compilation of non-AOSERP water quality data

Year of Publication: 1981

Abstract:
Studies of the water quality of the Athabasca Oil Sands area (Figures 1 and 2) streams, rivers, and lakes have been conducted by numerous organizations and government agencies since the 1950’s. The earlier studies involved efforts by provincial and federal government departments interested in ascertaining the suitability of these surface waters for various uses and concerned with the protection of human health and aquatic environments. Groups involved in subsequent studies collected surface and groundwater samples with a greater interest in the development of the Athabasca oil sands. Unfortunately, most of the groups did not provide documentations of sampling sites or the wide variety of sample collection, storage, and analysis procedures they used. Subsequent to the establishment of the Alberta Oil Sands Environmental Research Program (AOSERP), a program established by an agreement between the governments of Alberta and Canada in February 1975 (amended September 1977), a number of AOSERP projects involving water quality sample collection and analysis were instituted. These projects followed AOSERPs general objectives (Smith et al. 1979) which were, specifically, the definition of baseline states and detection of changes that might be caused by the development of the Athabasca oil sands. Under the regional surface water quality monitoring program (AOSERP Project WS 1.2.1, formerly HY 2.8.1) the standardization of sampling sites, procedures, and analysis received significant attention. A documentation of the locations of the water quality sampling sites, sampling, analytical, and quality control methods used; the volume and availability of assembled data; and a comprehensive appraisal of the quality of the data base.

Water quality of the Athabasca oil sands area: A regional study

Authors Corkum, L. D.
Year of Publication: 1985

Abstract:
This report is part of a series of research reports that describes the results of investigations funded under the Alberta Oil Sands Environmental Research Program, which was established by agreements of the Governments of Alberta and Canada in February 1975. This ten year program was designed to direct and co-ordinate research projects concerned with the environmental effects of development of the Athabasca Oil Sands in Alberta. The objectives of this report are to summarize water quality constituents in the AOSERP study area and to examine relationships between these constituents and changes in land formation, hydrology, and development.

Water quality overview of Athabasca River Basin

Year of Publication: 1985

Abstract:
This report overviews major water quality patterns and trends for the Athabasca River and its major tributaries. In doing so it compares water quality data with surface water quality objectives, identifies spatial and temporal patterns, defines major factors affecting water quality, characterizes the relationship between basin hydrology and water quality and identifies river reaches with similar water quality characteristics. The data analyzed for this overview assessment include historical water quality records collected since 1970 at three fixed station network locations (Jasper, Town of Athabasca and Ft. McMurray), and the results of six basin wide synoptic sampling surveys done seasonally during 1984 and early 1985. The historical data define long term trends, whereas the synoptic surveys provide information on spatial patterns. Results indicate that except for the St. Regis Pulp Mill at Hinton, point source effluents from municipal and industrial plants have no broadly based influence on river water quality. In almost all instances, tributary streams account for 90% or more of all measured constituent 1oadings. At low river flows the Hinton Pulp Mill does affect river water quality for a distance of 50 to 75 km. Many of the Alberta Surface Water Quality Objectives (ASWQUO) are regularly exceeded, however most of these exceedances are not attributable to point or nonpoint source impacts. These provincial objectives do not account for regional variations in natural water quality. Comparison with Environment Canada's use specific water quality objectives indicate Athabasca River water can be used for all beneficial uses except contact recreation, which is 1imited much of the year by low water temperatures and high turbidity. Certain objectives for aquatic life and wildlife are occasionally exceeded, however, these violations are due to natural causes and pending further investigation are not thought to be significant. Three water quality zones can be defined for the Athabasca River. The Foothills Reach, between Jasper Park boundary and Ft. Assiniboine, is characterized by fast flow and good overall water quality conditions. Alkalinity and hardness 1evels are elevated, reflecting the mountain origin of the water; yet the suspended solids, organic carbon and nutrient contents are low. The Hinton pulp mill is the only significant anthropogenic impact. Coal mining activity in the upper tributaries has no broad based effect on the mainstem river system. In contrast, very different water quality conditions are experienced in the river reach situated between Ft. McMurray and Lake Athabasca. Suspended solid 1evels are high much of the year, as are associated parameters like organic carbon, particulate nutrients and metals. These constituents are derived from upstream tributaries and channel re-suspension, rather than municipal or industrial effluents. The lower reach al so has a unique major ion chemistry created by loadings from the Clearwater River. The intermediate reach between Ft. Assiniboine and Ft. McMurray is a transition zone. Along this stretch, alkalinity and hardness levels decrease, while most other constituent concentrations increase due to tributary loadings. Based upon statistical analysis of the historical water quality database three distinct water quality seasons are defined. These include the ice cover interval, and two open water periods, from ice off to July 31 and August 1 to freeze-up. Water quality in the early openwater season is controlled by local and mountain snowmelt runoff and a rising hydrograph. The 1ate openwater season is affected by a falling hydrograph, summer rainstorms in the Interior Plains and maximum instream biological activity. Except for some tributaries the existing database adequately defines baseline water quality conditions throughout the basin. Future work should emphasize expansion of the fixed station water quality monitoring network, definition of river assimilation processes, development of basin specific water quality objectives, further work on trace organic compounds and more detailed definition of parameter inter-correlation and discharge dependence.

Water resources use and management issues for the Peace Athabasca and Slave River basins: Best/worst analysis of survey questions about threats and actions

Authors Williams, M.
Year of Publication: 1996

Abstract:
Two of the objectives of the Other Uses Component of the Northern River Basins Study were to determine which water management problems or issues were of greatest concern to basin residents and to recommend a series of management actions to address these concerns. Information about water management issues and actions was collected as part of surveys conducted with a random sample of northern households (Project 4121-D3) and with various stakeholder groups (Project 4121-D4). As part of these surveys, respondents were asked to choose the best and worst examples of various sets of threats to water quality/quantity and of possible management actions. The responses to the two sets of Best/Worst questions were analyzed using logistic regression. This analysis produced the following estimates: 1) the probability that each of 11 possible threats to water quality/quantity will be selected as the area of most concern; and 2) the probability that each of 11 possible management actions will be selected as the most effective response to such concerns The probabilities produced by this analysis can be ranked from lowest to highest to determine the preferences of northern households and various stakeholder groups within the basin. The results of the analysis of threats to water quality and quantity showed fairly consistent results among stakeholder groups and among the 12 regions used in the household survey. The top two perceived threats to water quality/quantity proved to be: • discharges from pulp mills; and • industrial wastes/tailings ponds. There was considerable variability in the ranking o f the remaining threats, especially among stakeholder groups. Furthermore, the top two threats were perceived to be of much greater concern than all of the nine remaining threats. In terms of recommended management actions, there was much more variability in the results. Overall there was greatest support among households and stakeholder groups for developing a management plan for the entire basin. However, some groups placed higher emphasis on preserving and maintaining ecosystems or reducing industrial effluent loads.

Water resources use and management issues for the Peace Athabasca and Slave River basins: Implementation of stakeholder surveys February to April 1995

Authors Reicher, P.
Year of Publication: 1996

Abstract:
This report describes the implementation of a survey of: interest groups, industries and municipal governments, agriculture associations, agricultural service boards, commercial fishermen, commercial recreation business owners, river transportation operators, trappers, and general stakeholders such as environmental groups, recreation clubs, Native Friendship centres and professional associations. The objective of this project was to collect information about various stakeholders and their uses of the aquatic resource. The survey was designed to employ a variety of approaches so that stakeholder concerns, attitudes and values could be assessed in parametric (quantifiable) and non-parametric measures and to minimize the filtering of information by the subsequent analyses.

Water resources use and management issues for the Peace Athabasca and Slave River basins: Results of the household and stakeholder surveys January to April 1995

Year of Publication: 1995

Abstract:
This study was undertaken on behalf of the Northern River Basins Study in response to one of the 16 questions posed by the Study Board at the outset of the study. This question is who are the stakeholders and what are the consumptive and non-consumptive uses of water in the Peace, Athabasca and Slave river basins? This report attempts to answer this question using the results of surveys conducted with stakeholders and a random sample of households in the northern river basins. The information contained in this report is based on completed questionnaires from 718 households (53 percent response rate), and from 183 of 602 stakeholder groups (30 percent response). The results of the surveys are summarized below for individual stakeholder groups. General Public The key stakeholders are the residents of the Peace, Athabasca and Slave river basins. In 1991 there were 268,690 people living in the basins, with about 3,000 of these people living in the NWT. The main consumptive use of water for this group is drinking water. While 55 percent of basin residents obtain their drinking water supplies from municipal water systems and 31 percent use groundwater from wells, most of the remainder use water from surface-water sources including rivers, lakes and dug-outs. Between 40 and 55 percent of households that rely on surface water sources employ some form of water treatment. About 10 percent of people who use river water claim that this water has acquired a chlorine taste during the past 10 years, even though none of them use chorine as a water treatment method. About 72 percent of basin households participate in one or more types of water-based recreation. Total recreational activity amounts to about 1.80 million trips per year. About 34 percent of households use sites along the mainstems of the major rivers in the basin, including the Athabasca and Peace rivers. These sites account for 21 percent of trips to the three sites most preferred by basin residents. About 10 percent of households that participate in water-based recreation believe that the mainstems of the river have become dirtier over the last 10 years. About 54 percent of basin households go fishing and, on average, they catch 23.3 kilograms of fish per year. Walleye and northern pike account for 25 percent of the total catch. Just over one-third of fishermen eat all or part of their catch and average consumption is 13.6 kilograms per year, although much lower consumption is reported in the Smoky/Wapiti area. About 14 percent of households that participate in water-based recreation have observed various changes in fish populations over the last 10 years. These changes include reduced fish populations, smaller fish, more disfigurations and growths, and an oily taste to the fish Municipal and Local Government Some 321 licences for 28,800 acre-feet of water per year have been issued to municipal and local governments in Alberta for purposes of domestic consumption This use accounts for nine percent of licenced water withdrawals on the Athabasca River and 15 percent of withdrawals from the Peace River. Only three percent of local and municipal governments that responded to the survey believe that their treated drinking water does not meeting drinking water standards. Thirty-six percent of water plant operators believe that the quality of raw water supplies is the most important factor affecting the quality of treated water. About half of plant operators feel that the quality or quantity of their raw water supplies has deteriorated over the last 10 years. About 80 percent of municipal and local governments treat their sewage before release to surface water sources and 54 percent of these use only primary sewage treatment. About 31 percent of households that obtain drinking water from municipal treatment plants are concerned about the quality of this water and 28 percent use some form of additional treatment, usually filtration. Agriculture There are about 13,900 farms in the study area. About 26 percent raise livestock while 29 percent produce grains or oilseeds and 41 percent are mixed farmers. The remainder are specialty farms. Farms in the NRBS account for about 17 percent of Alberta cattle production. Watering of livestock and irrigation are the main uses of water. A total of 194 irrigation water licences for 7144 acre-feet of water have been issued in the Alberta portion of the basin. Irrigation accounts for two percent of water withdrawn from the mainstem of the Peace River. About 85 percent of grain and oilseed farms use herbicides. These farms are located mainly in the Peace River drainage above the Town of Peace River. Over 80 percent of these farms also use fertilizers. About 85 percent of livestock operations spread their manure onto their land. Industrial Water Users Industry is the biggest consumer of water in the region. Licences totaling 430,600 acre-feet of water have been issued for industrial purposes and 52 percent of this is from the Athabasca River mainstem and eight percent is from the Peace River. Water use practices vary by industry. Companies in the forest sector use between 40 and 80 percent of their allocations, recycle 40 percent and discharge about 60 percent of what they withdraw. In comparison, the majority of oilfield injection companies use more than 60 percent of their licence, recycle about 20 percent and return about 20 percent back to surface-water sources. Less than 10 percent of companies have seen any changes in water quality or quantity in the last 10 years. Companies in the oil and gas sector expect their need for water to decline in the next 10 years, while some forestry operations expect their needs to grow. Commercial Recreation Companies, Trappers, Commercial Fishermen and River Transportation Various companies and individuals are directly or indirectly dependent on water resources in the basins for their livelihood. Some of the 51 commercial recreation companies in the basin offer river tours, especially on the Peace and Clearwater rivers, and they are very concerned about water 1 quality and quantity. Although the other types of operations may not directly use northern rivers, any change in water quality or fisheries can affect the tourist potential of the region and affect their businesses. About 50,000 people per year use the services of commercial recreation operations in the basin, including one-quarter of all non-resident visitors to the area. The commercial fish harvest from lakes in the NRBS area amounts to about 1.4 million kilograms per year. This represents about two-thirds of the total Alberta commercial fish harvest. No commercial fishing occurs in the mainstems of the Peace, Athabasca or Slave rivers. There are about 400 active commercial fishermen in the basin, and they are not currently concerned about water quality in the basin. However, they believe that contaminated fish from river mainstems may move into lakes and affect commercial fish harvests in the future. Commercial fishermen eat part of their catch: about 48 kilograms of fish per year. There are about 2,400 active trappers in the NRBS area and they produce about $1.3 million in furs per year, mostly beaver, muskrat and coyotes. About one-quarter of these people trap within 10 kilometres of the river mainstems. In most parts of the basin, trapping along the mainstems of the river accounts for less than 10 percent of animals trapped. However, more than 50 percent of the harvest in the Peace-Athabasca Delta comes from river channels. Only 40 percent of trappers have observed a decline in furbearer populations in recent years, and part of this is due to natural cycles. The mainstem of the Athabasca River is still used as a transportation route, with volumes of freight depending on population growth and economic activity in the Peace-Athabasca Delta. Stakeholder Issues and Concerns The surveys provided an opportunity to explore the water management issues and concerns of importance to basin residents and stakeholders. Households in the basin generally believe that water quality is a problem in the basin. Only 16 percent agree completely or partially with a questionnaire statement that water quality is “not really a major issue at the moment”. In contrast, 38 percent agree with the statement that “pollution of northern rivers is only a concern in a few locations”, while 75 percent agree that “contamination of northern rivers is a major problem”. Nearly 40 percent of households throughout the basin see pulp mills as the most important factor affecting water quality in the basin. Most stakeholder groups also believe that pulp mills are the prime factor affecting river health. Other major factors of concern to households, in order of importance, include municipal sewage, other industries, logging, and agriculture. In most cases, northern residents feel that these activities have adversely affected fish populations and water quality by introducing contaminants and pollutants into northern rivers. About two-thirds of households concerned about these factors believe that they or members of their household have been directly affected. While impacts on drinking water and human health are of some concern, more households are worried about the effects that these activities are having on fishing and other recreational activities in the basin. In most cases, households feel that increased regulation should be used to better control activities that affect water quality and quantity. About 75 percent of households and 66 percent of basin stakeholders disagree with the statement that “existing water management regulations are interfering with economic development in the basin”. Nearly 55 percent of households throughout the northern river basins propose that water quality be used to assess river health, with measurements being taken on a monthly basis. In describing future monitoring, 40 percent prefer that government be responsible for monitoring water quality while 30 percent want an independent agency to do the job. Only three percent feel that industry should be responsible for monitoring. However, nearly half of households believe that industry should pay for water-quality monitoring. Households and stakeholders were give the opportunity to list up to three recommendations that they feel should be made by the NRBS Board. Sixty percent of households responded to this question. The most common recommendation, made by 23 percent of households who responded to this question, is that the NRBS Board recommend that effluent loads be reduced. Another 21 percent suggest that industrial activities be better monitored while 17 percent want the NRBS Board to recommend better enforcement of pollution laws. Twelve percent of households want the Board to recommend that certain activities, such as logging and the operations of dams, be stopped or better controlled. While only four percent of households think that the NRBS Board should recommend the development of a basin management plan, 80 percent of households and 75 percent of stakeholders agree with a statement that “no further effluent discharges be allowed until a basin management plan has been completed”. The results of the household survey suggest that basin residents want the NRBS Board to make recommendations that will act quickly to resolve current problems. Future Management of the Basin In the survey, northern households and stakeholder groups were also asked whether they supported the idea of establishing some sort of ongoing, intergovernmental and stakeholder committee responsible for the protection and use of the northern river basins. The survey included several questions about the functions of such a committee. Between 70 and 80 percent of households in all regions within the basin support the establishment of a management, committee. Some of the stakeholder groups are less supportive of this idea. More than 75 percent of households believe that a committee should be responsible for providing advice to the federal, provincial and territorial governments, coordinating and conducting research, preparing a basin management plan, developing regulations, developing education programs, and overseeing enforcement. In contrast, only 51 percent feel that the committee should issue licences or permits. Industrial stakeholders believe that the committee should only have an advisory, research and education role and should not be responsible for regulatory functions. Over 82 percent of households are willing to participate on the committee, either as a committee member or as formal or informal advisors. In contrast, less than 37 percent of industrial water users, municipal and local governments, and agricultural groups are willing to participate on the committee.

Water resources use and management issues for the Peace Athabasca and Slave River basins: Stakeholder screening survey

Authors Hoare, T.
Year of Publication: 1995

Abstract:
Project 4121-D1, the Stakeholder Screening Survey was undertaken to build on the data collected in Project 4101-B1. Project 4101-B1 identified stakeholder groups that use or have an interest in the Peace, Athabasca and Slave River systems and recommended a workshop process for identifying the concerns of the stakeholder groups about water use in the three river systems. In Project 4121-D1, these organizations were surveyed to elicit sufficient information about the stakeholder groups to plan stakeholder workshops and to identify in a preliminary way the issues that should be addressed in the workshops. As well, through the survey process, a more complete stakeholder list was developed.

Year of Publication: 1996

Abstract:
The objective of Project 4121-D3 was to undertake a survey with a random sample of people residing in the northern river basins in order to collect information about these people, their use of the aquatic resources of the basin, and their attitudes and opinions about present and future water management in the basins. This survey was undertaken to help answer Study Board question #3: Who are the stakeholders and what are their consumptive and non-consumptive uses of the water resources in the river basins? The household survey employed a sampling strategy and questionnaire that were developed as part of previous NRBS projects. The basic approach involved contacting a stratified, random sample of 1,200 households by telephone, soliciting their cooperation with the survey, mailing them the questionnaire, calling them to remind them to complete the survey and even conducting the survey over the telephone, if required. The study area was broken into 12 regions and initial intentions were to send questionnaires to at least 90 households in each region, and 180 in each of the two larger regions. As the project progressed, this number was increased to 100 for most regions and 200 in the larger regions. The questionnaire was pretested by 20 households before full implementation occurred. A total of 2,621 households were screened in order to find 1,400 that were willing to complete the survey. This represents a participation rate of 53.4 percent. At the end of the study, 714 questionnaires had been completed, representing a 51 percent response rate. The most common reason for not completing the questionnaire was that the household was no longer interested in the survey. Survey results were then coded into two data bases: one for written comments and the other containing numeric and coded information. Analysis of this information is to occur as part of future NRBS projects.

Water security problems in Canada's oil sands

Year of Publication: 2013

Abstract:
Systems methodologies are employed to investigate water quantity and quality problems in Canada’s oil sands from a multiple-objective-decision-making viewpoint. Because water is one of the most important elements for human survival, many countries consider water issues to be of vital concern with respect to national security. Likewise, Canada is not an exception in terms of addressing its water resources problems as being of great import. In particular, water issues, such as large-scale water usage and troublesome polluted water disposal concerns connected to Canada’s oil sands industries, must be resolved. In this paper, Canada’s oil sands are described with respect to their characteristics, scale, and location. Then, technologies for recovering bitumen from oil sands and processes for upgrading the bitumen are discussed in terms of water consumption and water disposal. In addition, the environmental impacts and challenges with regards to water quantity and quality in Canada’s oil sands are examined in order to understand conflicts that have arisen in recent years. Multiple-criteria decision analyses based on the ProGrid methodology are carried out in order to grasp the structure of the conflict over alternatives for using and treating the water resources in oil sands development in Canada. An evaluation matrix, comparing the multiple criteria, is built, and the Language Ladders with different weights are established to allow the various groups of experts to evaluate the alternatives. Based on their evaluations, alternative solutions for the utilization of the water resources in Canada’s oil sands are prioritized with respect to the critical criteria using the ProGrid methodology. In conclusion, the strategic issues in water resources are addressed and priorities are determined to enhance decision-making.

Water stewardship in the lower Athabasca River: Is the Alberta government paying attention to aboriginal rights to water?

Year of Publication: 2011

Abstract:
This paper examines the status of aboriginal rights to water in the Lower Athabasca River Basin. It starts from the premise that Aboriginal peoples living in the Athabasca oil sands region have constitutionally protected water rights, and inquires whether or not these rights are acknowledged and protected by the Alberta government. In the first part of the paper, we discuss the impacts of oil sands developments on Aboriginal water rights. We first review the sources of negative impacts of development on water resources, as described in the scientific literature, we then outline the effects of such impacts on Aboriginal peoples living downstream from these developments. First Nations have many concerns about the impacts of industrial water use and pollution on water resources, notably on the fish and wildlife populations on which they depend, on their transportation needs and on their health. We identify some of the ways in which they have brought these concerns forward to government. In the second part of the paper, we briefly address governments’ obligations, both substantive and procedural, to ensure the protection of the water rights of Aboriginal peoples. We suggest that the promise of rights recognition and rights protection embodied in section 35 of the Constitution Act, 1982 imposes an obligation on government to actively protect these rights, not only to refrain from infringing them. In the third part of the paper, we examine how the Alberta government is meeting its obligations to First Nations as it allocates and manages the region’s water resources in the Athabasca oil sands region while overseeing the development of oil sands resources. The issues are dealt with under the following headings: water management planning initiatives, approval of oil sands development and monitoring the impacts of industrial development on the Lower Athabasca River system. Of the various water management planning initiatives in the region, we review the following: the Muskeg River Comprehensive Water Management Plan, the Water Management Framework for the Lower Athabasca River, the Athabasca River Watershed Management Plan and the Lower Athabasca Regional Plan. We describe each initiative and assess whether they acknowledge the rights to water of First Nations, and whether they allow for adequate consultation with Aboriginal peoples and accommodation of their rights. Next, we discuss the approval process for oil sands development and ask whether it deals with potential impacts on aboriginal or treaty rights to water. These issues are examined more closely in a case study of the Kearl Oil Sands Project review and EUB decision. Finally, based on a review of the findings of several scientific reports released in the past two years, we briefly examine how government monitors the impacts of industrial development on the Lower Athabasca River system and on the water rights of Aboriginal peoples.

Water use in Canada's oil-sands industry: The facts

Authors Lunn, S.
Year of Publication: 2013

Abstract:
Canada's oil-sands industry is often perceived as having poor environmental performance. One focus area is the use of water for oil-sands production. Bitumen from oil sands is produced by surface mining or by in-situ thermal extraction. Both technologies are water-based. The oil-sands deposits are situated in northern Alberta, where the river basins have 87% of the provincial average annual water supply but only have 13% of the demand. Oil-sands operators have made significant progress in improving freshwater use productivity (intensity), and water use represents a small percentage of natural supply. For in-situ production, the 2010 freshwater use productivity for the industry was 0.43 units of freshwater per unit of bitumen produced. As an example of continuous improvement, the Imperial Oil Cold Lake in-situ oil-sands operation has improved freshwater use productivity by 90% since 1985 through produced-water recycling and the use of deep saline groundwater. The in-situ oil-sands industry will remain a relatively small water user into the future (2030) using an estimated 0.04 to 0.09% of available supply from the three river basins where it is situated. For oil-sands mining, most of the source water comes from the Athabasca River. The average water-use productivity for oil-sands production between 2006 and 2011 was 2.5 units of Athabasca River water per unit of bitumen and synthetic crude oil produced (3.6 for all freshwater sources). In 2011, the oil-sands mining industry used 0.54% of the annual Athabasca River flow and 3% of the lowest 2011-2012 winter weekly flow. For growth forecasts to 2030, it is estimated that the oil-sands mining industry will require 1.4% of the average annual flow of the Athabasca River. Overall, by 2030, it is projected that the entire oil-sands industry will use less than 0.4% of Alberta's average annual water supply to produce 80% of Canada's total oil production.

Water-yield estimates for critical loadings assessment: Comparisons of gauging methods versus an isotopic approach

Year of Publication: 2008

Abstract:
An isotope mass balance technique is applied to quantify water yield and refine a steady-state critical acid loadings assessment for 49 lakes in hydrologically complex, wetland-rich terrain of northeastern Alberta. The approach uses physical and climatological data combined with site-specific measurements of evaporative isotopic enrichment of 2H and 18O in lake water to measure lake residency and ungauged runoff to lakes. Mean water yields to individual lakes across the region over a 3-year period are estimated to range from 5 to 395 mm·year–1, with a standard deviation of two times the predicted estimates based on interpolation of gauged stream flow from broad-scale watersheds in the area. Comparison of the method with longer-term Water Survey of Canada hydrometric data suggests very similar average water yields for moderate- to large-sized watersheds. However, the isotope-based estimates appear to capture extreme low water yields in flat, disconnected areas and extreme high water yields in other areas thought to be related to stronger connections to regional groundwater flow systems. For aquatic ecosystems of northeastern Alberta, an area expected to be affected by acid deposition from regional oil sands development, continued refinement of the technique is important to accurately assess critical loads for ungauged systems, particularly those in low-yield settings.
