EXECUTIVE SUMMARY EXECUTIVE SUMMARY

Dover Operating Corp. (Dover OPCO) proposes to develop and operate a commercial scheme for the recovery of bitumen from the McMurray formation approximately 95 km northwest of Fort McMurray, Alberta. This scheme will include the use of in situ steam assisted gravity drainage (SAGD) extraction, well pairs and two on-site steam generation and oil water treatment plants. The Project is submitted under the name of the Dover Commercial Project (the Project).

This report presents the baseline information on water quality conditions for the Project Aquatics Regional Study Area (RSA).

Water and sediment quality samples were collected within and near the LSA in 2009 and 2010, to characterize existing baseline water and sediment quality conditions. Historical baseline water and sediment quality data were compiled and summarized along with the results of the baseline sampling program. A detailed analysis of the data is included in this section.

The Water Quality Baseline study results indicate that water and sediment quality within and near the LSA are similar to those documented by other studies in the Oil Sands Region.

Larger waterbodies and watercourses, (i.e., Namur and Gardiner lakes and the Ells River) are generally mesotrophic, while smaller waterbodies and watercourses are typically eutrophic. Most of the measured concentrations were below water quality guideline values, although concentrations of total phenolics, total iron and total manganese in water were frequently above water quality guidelines. Less frequent guideline exceedances were observed in concentrations of fluoride, sulphide and total arsenic, barium, chromium, copper, lead, mercury, selenium, silver and zinc. Water quality in the RSA and LSA is similar to that observed in the region and reflects local background conditions

Most bottom sediments contained higher proportions of sand than silt and clay. Arsenic, fluorene and phenanthrene concentrations were occasionally measured above sediment quality guidelines. Sediment quality in the LSA is similar to that observed in the region and reflects local background conditions.

1 INTRODUCTION

Dover Operating Corp. (Dover OPCO) proposes to develop and operate a commercial scheme for the recovery of bitumen from the McMurray Formation approximately 95 km northwest of Fort McMurray, Alberta. The project is located in Townships 92, 93, 94, 95 and 96, Ranges 15, 16, 17 and 18 West of the Fourth Meridian (W4M) as shown on Figure 1. This scheme will include the use of in situ Steam Assisted Gravity Drainage (SAGD) well pairs and two on-site steam generation and oil/water treatment plants. The project is submitted under the name of the Dover Commercial Project (the Project).

The Project is within a 170 section (43,500 ha) area of land called the Dover Leases. The Project will be developed in five phases with each phase having 50,000 barrels per day (bpd) of bitumen capacity. Phase 1 will consist of the Dover North Plant (DNP) and associated well pads and infrastructure generally to the north of the plant. The Initial Surface Development Area (ISDA) will include these Phase 1 facilities, the access corridor and the source water well system.

Currently, 11 well pads are planned for the Phase 1 development. The access corridor consists of a permanent 51-km-long access road and a 67-km-long utility Right-of-Way (ROW) extending southeast from the DNP to other projects currently proposed and under review by the regulators. The source water well system includes 12 well pads and 20 km of infield access corridor consisting of both a permanent road and a pipeline corridor. The majority of this access corridor will also be used for SAGD well pad development as the Project progresses.

Phase 2 will involve an expansion of the DNP to 100,000 bpd capacity and associated SAGD well pads and infrastructure. An additional 140 well pads are ultimately planned for the northern portion of the Project to support continued development of Phases 1 and 2 of the Project.

Phases 3 to 5 will include construction and progressive 50,000 bpd expansions of the Dover South Plant (DSP) along with production pads and associated infrastructure. A total of 375 SAGD well pads are planned in the southern portion of the Dover Leases.

Both the northern and southern portions of the Dover Leases will undergo progressive development wherein SAGD well pads will be constructed, operated for typically 8 to 12 years and then reclaimed. Materials recovered during reclamation of pads will be re-used for new well pads to the extent possible. This progressive development and reclamation will result in a likely scenario of 175 well pads being either in construction, operation, or reclamation at any one time when the Project is in full production.

1.1 STUDY AREAS

1.1.1 Aquatics Regional Study Area

The Aquatics Regional Study Area (RSA) was based on potential effects from construction and operation of the Project on flows and water levels in watersheds in which the Project is located, including surface water/groundwater interactions. This RSA also contains other projects and activities that are considered in the Baseline and Planned Development Cases.

The Aquatics RSA is shown on Figure 2 and includes the following major watersheds and lakes:

Ells River basin (effective drainage area of 2,450 km2): The Ells River originates from Gardiner Lakes, and drains south (immediately east of the Project) and then to the east before discharging to the Athabasca River about 42 km east of the Project. The drainage for Joslyn Creek is within the Ells River basin but is 30 km to the east and it joins the Ells River very close to the mouth. Since this drainage is affected by proposed oil sands mining developments in its downstream reach, it was excluded from the RSA.

MacKay River basin (effective drainage area of 5,570 km2): The MacKay River basin drains the western and southern portions of the RSA. The MacKay River basin includes the Dover, Dunkirk, and MacKay sub-basins. The Dover River drains the majority of the southern Lease Area. The western of the Project area is drained by the Dunkirk River, a south-flowing tributary of the MacKay River at the upper MacKay River watershed. The MacKay River generally flows to the northeast before discharging into the Athabasca River about 45 km east of the Project. The Dover and Dunkirk rivers intersect at approximately 20 km and 90km upstream of the Athabasca River confluence, respectively.

Gardiner Lakes (Upper Gardiner Lake and Lower Gardiner Lake, total surface area of 50 km2): Gardiner Lakes are the headwaters for the Ells River, with the river originating at the outflow of Lower Gardiner Lake.

Namur Lake (surface area of 37 km2), Big Island Lake (surface area of 16 km2) and Sand Lake (surface area of 14 km2): These three large lakes are located in the headwaters of the Ells River system and all drain to the Gardiner Lakes.

The total area of the Aquatics RSA is approximately 796,000 ha. Namur Lake and Gardiner Lakes are considered to be regionally important as are the Ells and MacKay rivers (Westworth 1994).


Golder Associates

The northern portion of the RSA is comprised generally of uplands sloping to the northwest towards the Birch Mountains. This area is characterized by numerous small streams and drainages flowing to the southeast. A secondary direction for streams is along glacial striations that run from southwest to northeast. The southern portion of the RSA tends to have less variation in topography and a greater occurrence of wetlands. Many of the smaller unnamed streams tend to be poorly defined.

1.1.2 Local Study Area

The Local Study Area (LSA) covers approximately 62,000 ha and includes the Project footprint and the access corridor to the southeast (Figure 2). The LSA corresponds to that used for the terrestrial components.

These two study areas were used to define the level of detail of the baseline water and sediment quality study, with information collected and evaluated in detail for waterbodies and watercourses within and in the general vicinity of the LSA and compilation of historical water quality information compiled for the RSA.

1.2 STUDY OBJECTIVES

The following objectives were identified for the water quality and sediment quality components of this study:

compile existing information on water quality within the RSA;

compile existing information on sediment quality within and near the LSA;

describe and discuss existing water and sediment quality within and near the LSA;

where possible, discuss seasonal variation in water quality; and

compare existing water and sediment quality in the LSA with relevant guidelines for the protection of aquatic life, human health and wildlife health.

2.3 METHODS

This section outlines the methods used to characterize water and sediment quality in the study areas, including field sampling, data compilation and analysis.

2.3.1 Field Sampling

At each waterbody site, a composite sample was collected with a 1 L bottle which was used to collect six grab samples from each of three randomly selected locations, for a total of 18 L. All water collected at a waterbody was added to a clean 20 L pail and was mixed before filling sample bottles provided by the analytical laboratories.

At watercourse sites, individual grab samples were collected from just below the water surface, at approximately mid-channel.

Field parameters including dissolved oxygen, pH, specific conductivity and water temperature were measured at each water quality sampling site near the water surface. Single measurements were taken at stream sites and the median of measurements taken at each of the three random sites on each lake were assigned to the composite samples. Field measurements were made using a field-calibrated multi-meter (YSI 556 or equivalent).

Water samples were collected, preserved, stored and shipped in accordance with established technical procedures for water quality sample collection that are consistent with standard methods (APHA 1992; Environment Canada 1993). For dissolved parameter testing, 1 L water samples were collected and filtered on the same day. Preservatives were added to sample bottles as required by the analytical laboratories. Summer and fall 2009 water quality samples were submitted to ALS Environmental in Fort McMurray, Alberta for analysis of parameters described below.

Water quality samples collected in winter and spring 2010 were split into two parts and shipped to separate laboratories for analysis: one part to the Alberta Innovates – Technology Futures in Vegreville, Alberta, for ultra low detection analysis of methyl mercury; and one part to the Maxxam Analytics in Fort McMurray, Alberta, for analysis of all other parameters described below. These samples were analyzed for a suite of detailed chemical parameters, which provide a broad profile of in-stream water quality and are generally consistent with the parameter list used by the Regional Aquatics Monitoring Program (RAMP 2010). Individual water quality sample results from the program are provided in Attachment A.


Golder Associates

The analytical parameters analyzed for water quality include the following:

Conventional: pH, conductivity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), hardness, total alkalinity, Dissolved Organic Carbon (DOC), Total Organic Carbon (TOC) and colour.

Major ions: bicarbonate, calcium, carbonate, chloride, magnesium, potassium, sodium, sulphate and sulphide.

Nutrients and biological indicators: ammonia, nitrate, nitrite, Total Kjeldahl Nitrogen (TKN), total and dissolved phosphorus, Biochemical Oxygen Demand (BOD) and chlorophyll a.

Organics: naphthenic acids, total phenolics and total recoverable hydrocarbons.

Total and dissolved metals: aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, chromium, cobalt, copper, iron, lead, lithium, manganese, mercury, methyl mercury, molybdenum, nickel, selenium, silver, strontium, thallium, titanium, uranium, vanadium and zinc.

Sediment samples were collected using an Ekman grab. Three grab samples were collected and mixed in a metal pan to prepare a composite sample. Sample jars and bags were filled and submitted to ALS Environmental in Fort McMurray, Alberta, for analysis of particle size, carbon and organic content, total metals, Polycyclic Aromatic Hydrocarbons (PAHs) and alkylated PAHs. These parameters are also generally consistent with those used by RAMP (2010). Individual sediment quality sample results from the program are provided in Attachment B.

Quality Control samples were also collected during each sampling period. Blanks were used to assess potential sample contamination during collection, shipping and analysis; duplicate samples were used to check intra-site variation and precision of field sampling methods; and split samples were used to test the precision of laboratory analyses. Details of the Quality Control program are provided in Attachment C.

2.3.2 Data Analysis

2.3.2.1 Water Quality

Results of the 2009 to 2010 water quality sampling program were combined with available historical data, and the seasonal median, minimum and maximum values were calculated. Consistent with RAMP (2010), seasons were defined as winter (November through March), spring (April and May), summer (June through August) and fall (September and October). Historical metals data associated with high analytical detection limits relative to recent detectable results (e.g., mercury and silver prior to 2001) were removed from the data sets prior to this summary, as such results are not representative of baseline conditions and would not add value to the baseline analysis.

Water quality data were evaluated by comparing concentrations of individual parameters with published water quality guidelines for the protection of freshwater aquatic life, human health and wildlife health (AENV 1999; CCME 1999; Health Canada 2008; U.S. EPA 2002, 2003a,b). In cases where several guidelines were available for a parameter, the most stringent guideline was used, as recommended by Alberta Environment (AENV 1999), unless otherwise noted. A summary of the relevant water quality guidelines is provided in Table 2.

Water quality guidelines have been developed for many parameters, typically based on measured responses of standard test species (fish and invertebrates) to known concentrations of chemicals. Guidelines for nutrients (e.g., total phosphorus [TP] and total nitrogen [TN]), which are non-toxic, correspond to levels, below which the harmful effects of nutrient enrichment (e.g., algal blooms) are unlikely. Chronic guidelines provide protection from long-term, sub-lethal effects (e.g., reduced growth or impaired reproduction). Acute guidelines are intended to protect aquatic organisms from short-term, usually lethal effects.

Concentrations of parameters measured to evaluate baseline water quality may be affected by several factors. Natural conditions associated with surficial geology, interactions between surface water and groundwater, physical features of the waterbody and its drainage basin, local weather and seasonal hydrological changes and many other factors can influence baseline water quality. For example, many elements can be tightly bound to suspended sediments during spring runoff, resulting in elevated concentrations of metals (e.g., aluminum, iron and manganese) and nutrients (e.g., TP) in surface water. Consequently, it is common to measure some water quality parameters above regulatory guidelines in remote areas that are not directly affected by human activities. However, these parameters are generally not bioavailable to aquatic organisms.

Parameter concentrations that are slightly higher than water quality guidelines under baseline conditions are generally not considered to be of concern to aquatic life. Guidelines based on laboratory toxicity testing tend to be conservative, because such guidelines frequently incorporate a safety factor. Moreover, aquatic species are adapted to the natural levels of chemicals present in the waters they inhabit. Therefore, concentrations of water quality parameters that are greater than guidelines do not necessarily indicate that water quality has been compromised by human activities or natural factors.

Three qualitative scales were used to categorize the trophic status of watercourses and waterbodies in the results section of the report. A total phosphorus scale developed by Vollenweider and Kerekes (2002) was used to categorize the trophic status of waterbodies (Table 3). This scale also defines Canadian Council of Ministers of the Environment (CCME [CCME 2004]) trigger ranges for management of freshwater systems. A total phosphorus scale developed by Dodds et al.

Finally a chlorophyll a scale developed by Mitchell and Prepas (1990) was used to also categorize the trophic status of waterbodies (Table 4).

2.3.2.2 Sediment Quality

Sediment quality data were evaluated through a comparison of individual parameter concentrations to the CCME guidelines shown in Table 5. These guidelines include the CCME Interim Sediment Quality Guidelines (ISQG) and Probable Effects Levels (PEL) (CCME 1999).

Sediment quality can be influenced by a number of different factors. The surficial geology, physical features of the lake or stream, seasonal hydrological changes and biological factors can all influence sediment quality. This can result in concentrations of parameters exceeding guideline criteria under baseline conditions.

Parameter concentrations that are higher than sediment quality guidelines under baseline conditions are generally not considered to be of concern. As in the case of water quality guidelines, sediment quality guidelines based on laboratory testing tend to be conservative, because such guidelines frequently incorporate a safety factor. Moreover, aquatic species are adapted to the natural levels of chemicals present in the waters they inhabit, which, in the case of sediment quality, tend to reflect local geological conditions.

3 RESULTS AND DISCUSSION

3.1 WATER QUALITY

Baseline water quality within and near the LSA, and for two large waterbodies upstream of the LSA that are of traditional importance to stakeholders, is described in the following sections. A summary of the water quality data for waterbodies and watercourses within the RSA is provided in Attachment D. This data provides a historical overview that is used for comparison with data collected specific to this study.

3.1.1 Namur Lake and Gardiner Lakes

Namur Lake and Gardiner Lakes are large waterbodies in the headwaters of the Ells River watershed located near the northernmost extent of the LSA. The available water quality sample analyses for selected parameters in these lakes are summarized in Tables 6 and 7; a summary including all available water quality parameters is provided in Attachment E.

Namur Lake and Gardiner Lakes had pH values that were generally near-neutral to slightly alkaline, with maximum laboratory pH measurements of 8.7 in water samples collected in summer. However, there was a single fall field pH measurement in Namur Lake which was unusually high, and may reflect a measurement error. Dissolved Oxygen (DO) levels were observed below the acute or chronic guideline ranges for the protection of aquatic life in both lakes in spring, suggesting oxygen depletion under ice prior to spring break-up, and in Namur Lake in fall, which may indicate oxygen depletion due to stratification in late summer.

Some seasonal concentrations of fluoride were above the chronic aquatic life guideline in Namur Lake and Gardiner Lakes, while concentrations of other ions with water quality guidelines were below respective guideline values in all samples. Concentrations of TP in these lakes were observed above the chronic guideline for the protection of aquatic life in all seasons, with more frequent exceedances observed in Gardiner Lakes during winter and summer. Total nitrogen (TN) concentrations were above the chronic guideline in both lakes in winter, spring and summer. Chlorophyll a concentrations in the lakes were generally higher in summer than in winter, although high concentrations were observed in winter. Based on observed concentrations of chlorophyll a and median concentrations of TP, Namur Lake is mesotrophic to meso-eutrophic. The Gardiner Lakes are potentially eutrophic based on TP concentrations, but are mesotrophic based on chlorophyll a concentrations.

Naphthenic acids concentrations were non-detectable in Namur Lake samples and were not analyzed in Gardiner Lakes samples. Total phenolics concentrations in Gardiner Lakes were above wildlife health or chronic aquatic guidelines in winter, spring and summer, and in all seasons in Namur Lake, with the highest concentrations observed in summer. Total aluminum, barium, chromium, copper, iron, lead, manganese, mercury and zinc were above one or more water quality guidelines in a sample collected during spring in Namur Lake, which is likely related to inputs of suspended sediments during spring freshet. Of the limited metals data available for Gardiner Lakes, total manganese was measured at a concentration above the human health guideline in one sample collected during summer. With one exception, concentrations of PAHs in Namur Lake samples were below detection limits. A single detectable concentration of phenanthrene was below the water quality guideline in a sample collected in fall.

3.1.2 Small Waterbodies Within and Near the Local Study Area

A summary of available water quality sample analyses for selected parameters are provided in Table 8 for other small waterbodies within and near the LSA; a summary including all available water quality parameters is provided in Attachment E.

Smaller waterbodies within and near the LSA vary from slightly acidic to alkaline, with field measured minimum and maximum pH values outside water quality guideline ranges. Concentrations of DO were observed below acute and chronic guidelines for the protection of aquatic life in winter and summer, suggesting oxygen depletion under ice in winter and high sediment oxygen demand in some waterbodies in summer.

Observed concentrations of fluoride and sulphide were often above the chronic aquatic life guideline, while concentrations of other ions with water quality guidelines were below respective guideline values in all samples. Concentrations of TP and TN were observed above the chronic guideline for the protection of aquatic life in all seasons. Observed chlorophyll a concentrations were higher in summer than in spring and winter. Based on observed concentrations of chlorophyll a and TP, most of these small waterbodies are eutrophic.

Naphthenic acids concentrations were non-detectable in 24 of 27 samples and total phenolics concentrations were often above wildlife health or chronic aquatic guidelines in all seasons. Total aluminum, arsenic, chromium, copper, iron, manganese, mercury, silver and zinc were observed to be above one or more water quality guidelines in at least one season, and guideline exceedances appear to be more frequent in winter and spring than in summer and fall. However, the concentration associated with the chromium exceedance may have been a result of sample contamination and may not be representative of baseline conditions. Concentrations of PAHs were generally below detection limits, and detectable PAH concentrations were below water quality guideline values.

3.1.3 Ells River

Available water quality sample analyses for selected parameters for the Ells River within and near the LSA are summarized in Table 9. A summary including all available water quality parameters is provided in Attachment E.

The Ells River varies from slightly acidic to alkaline, with field-measured minimum and maximum pH values commonly outside water quality guideline ranges (Table 9). River water is generally well oxygenated, although DO levels were observed below acute or chronic guidelines for the protection of aquatic life in winter, spring and summer.

Observed seasonal maximum concentrations of fluoride were occasionally above the chronic aquatic life guideline, while concentrations of other ions with water quality guidelines were below respective guideline values in all samples. Maximum concentrations of TN were observed above the chronic guideline for the protection of aquatic life in all seasons, while TP concentrations were observed above the same chronic guideline in winter, spring and fall. Chlorophyll a concentrations were low, although data are limited. Based on observed concentrations of TP, the Ells River appears to be mesotrophic near the LSA.

Naphthenic acids concentrations were non-detectable in all samples and total phenolics concentrations were observed above wildlife health and chronic aquatic guidelines in all seasons. Total aluminum, chromium, iron, manganese and zinc were observed above one or more water quality guidelines in at least one season. However, the concentration associated with the chromium exceedance may have been a result of sample contamination and may not be representative of baseline conditions. Guideline exceedances generally appear to be more frequent in spring than in other seasons, likely reflecting suspended sediment input during spring freshet. Concentrations of PAHs were below detection limits in all Ells River samples.

3.1.4 Other Watercourses Within and Near the Local Study Area

Available water quality sample analyses for selected parameters in other watercourses within and near the LSA are summarized in Table 10; a summary including all available water quality parameters is provided in Attachment E.

Other watercourses within and near the LSA vary from slightly acidic to slightly alkaline, with field-measured minimum pH values below water quality guideline ranges in winter and summer (Table 10). These waters are generally well oxygenated, although DO levels were observed below acute and chronic guidelines for the protection of aquatic life in all seasons.

The limited amount of available sulphide concentrations were all above the chronic aquatic life guideline, while concentrations of other ions with water quality guidelines were below respective guideline values in all samples. Concentrations of TP and TN were observed above the chronic guideline for the protection of aquatic life in all seasons. Based on observed concentrations of TP, most of these smaller watercourses appear to be eutrophic.

Naphthenic acids concentrations were non-detectable in 44 of 49 samples and total phenolics concentrations were often above wildlife health and chronic aquatic guidelines in all seasons. Total aluminum, chromium, copper, iron, manganese, selenium and zinc were observed above one or more water quality guidelines in at least one season. However, the concentration associated with the chromium exceedance may have been a result of sample contamination and may not be representative of baseline conditions. Guideline exceedances by metals are generally more frequent in winter and spring than in summer and fall, with the exception of total iron which is elevated year-round. Concentrations of PAHs were generally below detection limits, and detectable PAH concentrations were below water quality guideline values.

3.2 SEDIMENT QUALITY

Available sediment quality sample analyses for selected parameters in waterbodies and watercourses within and near the LSA are summarized in Table 11; a summary including all available sediment quality parameters is provided in Attachment F.

3.2.1 Waterbodies Within and Near the Local Study Area

Sediments in most waterbodies sampled within and near the LSA contained higher proportions of sand than silt and clay. Total organic carbon content was generally low, ranging from 0.5 to 3.5%. Naphthenic acids concentrations were below detection limits.

Total arsenic concentrations were above the ISQG in some samples, while concentrations of other metals, when detectable, were below the ISQG. Concentrations of PAHs were generally low or below detection limits, with some detectable concentrations of naphthalene, fluorene and phenanthrene above the ISQG. Concentrations were not observed above PEL values.

3.2.2 Watercourses Within and Near the Local Study Area

Sediments in most watercourses sampled within and near the LSA contained higher proportions of sand than silt and clay. Total organic carbon content ranged from less than 0.4 to 9.9%. Naphthenic acids concentrations were below detection limits.

Total arsenic concentrations were above the ISQG in some samples, while concentrations of other metals, when detectable, were below the ISQG. Concentrations of PAHs were generally low or below detection limits, with some detectable concentrations of naphthalene and phenanthrene greater than the ISQG. Concentrations were not observed above PEL values.

4 SUMMARY

Water and sediment quality samples were collected within and near the LSA in 2009 and 2010. Historical baseline water and sediment quality data were compiled and summarized along with the results of the baseline sampling program.

Overall, the baseline study results indicate that water and sediment quality within and near the LSA are similar to those documented by other studies in the Athabasca Oil Sands Region. Most of the measured concentrations were below guideline values for both water and sediment samples. Larger waterbodies and watercourses, (i.e., Namur and Gardiner lakes and the Ells River) are generally mesotrophic, while smaller waterbodies and watercourses are typically eutrophic. Concentrations of total phenolics, total iron and total manganese in water were frequently above guidelines. In bottom sediments, concentrations above the ISQG were occasionally measured for arsenic, napthalene, fluorene and phenanthrene but likely reflect local geological conditions.

8 GLOSSARY

Acute Acute refers to a stimulus severe enough to rapidly induce an effect; in aquatic toxicity tests, an effect observed in 96 hours or less is typically considered acute. When referring to aquatic toxicology or human health, an acute effect is not always measured in terms of lethality.

Alkalinity A measure of water’s capacity to neutralize an acid. It indicates the presence of carbonates, bicarbonates and hydroxides, borates, silicates, phosphates and organic substances. It is expressed as an equivalent of calcium carbonate. The composition of alkalinity is affected by pH, mineral composition, temperature and ionic strength. However, alkalinity is normally interpreted as a function of carbonates, bicarbonates and hydroxides. The sum of these three components is called total alkalinity.

Baseline A surveyed or predicted condition that serves as a reference point on which later surveys are coordinated or correlated.

Basin A geographic area drained by a single major stream; consists of a drainage system comprised of streams and often natural or artificial (constructed) lakes.

Bioavailability The amount of chemical that enters the general circulation of the body following administration or exposure.

Biochemical Oxygen Demand

An empirical test in which standardized laboratory procedures are used to determine the relative oxygen requirements of wastewaters, effluents and polluted waters.

Bitumen A highly viscous, tarry, black hydrocarbon material having an API gravity of about 9 (specific gravity about 1.0). It is a complex mixture of organic compounds. Carbon accounts for 80 to 85% of the elemental composition of bitumen, hydrogen 10%, sulphur 5%, and nitrogen, oxygen and trace elements form the remainder.

Chlorophyll a One of the green pigments in plants. It is a photo-sensitive pigment that is essential for the conversion of inorganic carbon (e.g., carbon dioxide) and water into organic carbon (e.g., sugar). The concentration of chlorophyll a in water is an indicator of algal concentration.


Golder Associates

Chronic The development of adverse effects after extended exposure to a given substance. In chronic toxicity tests, the measurement of a chronic effect can be reduced growth, reduced reproduction or other non-lethal effects, in addition to lethality. Chronic should be considered a relative term depending on the life span of the organism.

Concentration Quantifiable amount of a chemical in environmental media.

Conductivity A measure of the capacity of water to conduct an electrical current. It is the reciprocal of resistance. This measurement provides an estimate of the total concentration of dissolved ions in the water (specific conductance is normalized to 25°C).

Dissolved Organic Carbon (DOC)

The dissolved portion of organic carbon water; made up of humic substances and partly degraded plant and animal materials.

Dissolved Oxygen (DO)

Measurement of the concentration of dissolved (gaseous) oxygen in the water, usually expressed in milligrams per litre (mg/L).

Drainage Basin A region of land that eventually contributes water to a river or lake.

Ekman Grab Cube-shaped mechanical device with a spring-loaded opening that is lowered to the bottom of a waterbody and triggered to close as to collect a sample of the bottom substrate.

Environmental Impact Assessment

A review of the effects that a proposed development will have on the local and regional environment.

Epilimnetic Localized in the surface layer of a waterbody.

Eutrophic The nutrient-rich status (amount of nitrogen, phosphorus and potassium) of an ecosystem.

Grab Sample A single sample collected at a particular time and place that represents the composition of the water only at that time and place.

Groundwater That part of the subsurface water that occurs beneath the water table, in soils and geologic formations that are fully saturated.

Headwater The source and upper reaches of a stream; also the upper reaches of a reservoir. The water upstream from a structure or point on a stream. The small streams that come together to form a river. Also may be thought of as any and all parts of a river basin except the mainstem river and main tributaries.

Hydrology The science of waters of the earth, their occurrence, distribution, and circulation; their physical and chemical properties; and their reaction with the environment, including living beings.


Golder Associates

Hyper-Eutrophic Trophic state classification for lakes characterized by high primary productivity and high nutrient inputs (particularly total phosphorus). Hyper-eutrophic lakes are characterized by abundant plant growth, algal blooms and oxygen depletion.

Initial Surface Development Area

The surface area containing all of the facilities that will be required for access and initial development of the subsurface bitumen associated with Phase 1 of the Dover Commercial Project; including the Dover North Plant, Phase 1 well pads gathering corridors and associated infrastructure, the main Dover Access Road and Utility Corridor and the wells, pipelines and infrastructure required for the non-saline water well system.

Invertebrates Any animal lacking a backbone, including all species not classified as vertebrates.

ISQG (Interim Sediment Quality Guideline)

Recommended maximum concentration of a chemical in sediment, intended to be protective of aquatic organisms.

In Situ Also known as “in place”. Refers to methods of extracting deep deposits of oil sands without removing the groundcover. The in-situ technology in oil sands uses underground wells to recover the resources with less impact to the land, air and water than for oil sands mining.

Local Study Area Defines the spatial extent directly or indirectly affected by the project.

Mesotrophic Trophic state classification for lakes characterized by moderate productivity and nutrient inputs (particularly total phosphorus).

Naphthenic Acid Generic name used for all the organic acids present in crude oils.

Nutrients Environmental substances (elements or compounds) such as nitrogen or phosphorus, which are necessary for the growth and development of plants and animals.

pH The degree of acidity (or alkalinity) of soil or solution. The pH scale is generally presented from 1 (most acidic) to 14 (most alkaline). A difference of one pH unit represents a ten-fold change in hydrogen ion concentration.


Golder Associates


Polycyclic aromatic hydrocarbons are a large group of organic compounds comprised of two or more aromatic rings and by-products of combustion. They are found in crude oil and a variety of products such as bitumen, asphalt, coal tar pitch volatiles, and unrefined or mildly refined mineral oils. Polycyclic aromatic hydrocarbons (PAHs) are emitted into the Canadian environment from both natural and anthropogenic sources. Forest fires, which release approximately 2000 tonnes of PAHs per year, are the single most important natural source of PAHs in Canada. However, since releases from that source are generally widely separated in time and space across the country, they do not result in continuous exposure in any specific area. Anthropogenic sources are numerous and result in emissions of PAHs into all environmental compartments

Probable Effects Level (PEL)

Concentration of a chemical in sediment above which adverse effects on an aquatic organism are likely.

Runoff The portion of water from rain and snow that flows over land to streams, ponds or other surface waterbodies. It is the portion of water from precipitation that does not infiltrate into the ground, or evaporate.

Sediments Solid material that is transported by, suspended in, or deposited from water. It originates mostly from disintegrated rocks; it also includes chemical and biochemical precipitates and decomposed organic material, such as humus. The quantity, characteristics and cause of the occurrence of sediment in streams are influenced by environmental factors. Some major factors are degree of slope, length of slope soil characteristics, land usage and quantity and intensity of precipitation.

Specific Conductivity A measure of the capacity of water to conduct an electrical current. It is the reciprocal of resistance. This measurement provides an estimate of the total concentration of dissolved ions in the water (specific conductance is normalized to 25°C).

Spring Freshet A spring thaw event resulting from snow and ice melt in rivers.

Steam Assisted Gravity Drainage

An in-situ oil sands recovery technique that involves the use of two horizontal wells, one to inject steam and a second to produce the bitumen.


Golder Associates

Suspended Sediments Particles of matter suspended in the water. Measured as the oven dry weight of the solids, in mg/L, after filtration through a standard filter paper. Less than 25 mg/L would be considered clean water, while an extremely muddy river might have 200 mg/L of suspended sediments.

Total Dissolved Solids (TDS)

The total concentration of all dissolved compounds solids found in a water sample.

Total Kjeldahl Nitrogen (TKN)

The sum of organic nitrogen; ammonia, NH3 and ammonium, NH4+

Total Recoverable Hydrocarbons

A term that refers to groups of petroleum hydrocarbons recovered using a solvent-specific extraction procedure. Hydrocarbons may include a wide range of fuels, oils and greases.

Total Suspended Solids (TSS)

A measure of the total concentrations of suspended solids in water.

Toxic A substance, dose or concentration that is harmful to a living organism.

Trophic Pertaining to part of a food chain, for example, the primary producers are a trophic level just as tertiary consumers are another trophic level.

Waterbody A general term that refers to ponds, bays, lakes, estuaries and marine areas.

Watercourse A general term that refers to riverine systems such as creeks, brooks, streams and rivers.

Watershed The entire surface drainage area that contributes water to a lake or river.

QUALITY ASSURANCE/QUALITY CONTROL RESULTS

Dover Commercial Project C-1 Quality Assurance/Quality Control December 2010

1 QUALITY ASSURANCE/QUALITY CONTROL

1.1 INTRODUCTION

Quality Assurance and Quality Control (QA/QC) practices determine data integrity and are relevant to all aspects of a study, from sample collection to data analysis and reporting. Quality Assurance encompasses management and technical practices designed to ensure that the data generated are of consistent high quality. Quality Control is an aspect of QA and includes the procedures used to measure and evaluate data quality, and the corrective actions to be taken when data quality objectives are not met. This appendix describes QA/QC practices applied during this study, evaluates QC data, and describes the implications of QC results to the interpretation of study results.

1.2 QUALITY CONTROL/QUALITY ASSURANCE PRACTICES

1.2.1 Quality Assurance

Quality Assurance applicable to this study cover three areas of internal and external management, as described below.

1.2.1.1 Field Staff Guidance

Field work was completed according to approved specific work instructions (SWIs) and established technical procedures (TPs). SWIs are standardized forms that describe exact sampling locations and provide specific sampling instructions, equipment needs and calibration requirements, required technical procedures, sample labelling and shipping protocols and laboratory contacts. They also provide specific guidelines for field record keeping and sample tracking. TPs are consistent with standard field methods described in the relevant scientific literature (e.g., Environment Canada 1993; American Public Health Association [APHA] 1992), and outline sample collection, preservation, handling, storage and shipping protocols.

During field work, field data were recorded on standardized field data sheets or in a bound field book, according to established field record-keeping procedures. Samples were documented and tracked using chain-of-custody forms and receipt of samples by the analytical laboratory was confirmed.


Golder Associates

One field crew member was responsible for managing the sample shipping process to ensure that:

all required samples were collected;

chain-of-custody and analytical request forms were completed and correct;

proper labelling and documentation procedures were followed; and

samples were delivered to the appropriate locations in a timely manner.

1.2.1.2 Laboratory

One member of the project team was designated as the lab liaison. To ensure that high quality data were generated, laboratories used for the sample analysis are accredited by the Canadian Association for Laboratory Accreditation Inc. (CALA). Under CALA’s accreditation program, performance evaluation assessments are conducted annually for laboratory procedures, methods and internal quality control.

1.2.1.3 Office Operations

Office-related QA included use of appropriately trained personnel for each task and senior review of work products at appropriate milestones, use of standardized data manipulation/summary tools, filing of data and project information according to standardized protocols and establishment of a data management system to ensure an organized consistent system of data storage, QC and retrieval.

1.2.2 Quality Control

1.2.2.1 Field Quality Control Procedures

The water quality field QC program consisted of the collection and analysis of field blanks, and duplicate and split samples. Each QC sample type is described below:

Field blanks consist of de-ionized water provided by the analytical laboratory, which is exposed to the sampling environment at the sample site and handled in the same manner as the surface water samples collected during the field program (e.g., preserved, filtered). Field blanks are used to detect potential sample contamination during sample collection, handling, shipping and analysis.


Golder Associates

Travel blanks consist of de-ionized water provided by the analytical laboratory in a set of sample bottles that is the same as would be used for a field sample, which is brought to the sample site but is not exposed to the sampling environment (i.e., travel blank sample bottles are neither opened in the field nor preserved/filtered) and shipped in the same manner as the surface water samples collected during the field program. Travel blanks are used to detect potential sample contamination during sample shipping, handling and analysis without influence of direct exposure to the sampling environment.

Duplicate samples are additional samples collected at the same time and location as surface water samples collected during a field program, using the same sampling methods. They are used to check within-site variation.

Quality Control samples collected during the field program accounted for approximately 10% of the total number of samples submitted for analysis. These samples were handled, stored and shipped along with field-collected surface water samples, and were submitted “blind” to the analytical laboratories, with the exception of travel blanks. Quality Control samples were analyzed for the same set of parameters as the samples collected from surface waters.

1.2.2.2 Office Quality Control Procedures

Key elements of office QC procedures included the following:

comparing sample data entered into the project database and data in report tables against final laboratory reports;

creating backup files before each major operation as data were being manipulated; and

verifying the accuracy of calculations performed to generate summary statistics.

Initial Data Screening

Upon receipt of water quality data from the analytical laboratory, a series of standard checks were performed to screen for potential data quality issues. These allowed potential re-analysis of samples to verify questionable data, or generate data for missing parameters. The following data checks were performed:

verification that all required parameters and samples were analyzed;

verification that data are reported using the appropriate units;


Golder Associates

logic checks: presence of zero values, comparisons of TDS and conductivity, hardness and alkalinity, total and dissolved phosphorus, total and dissolved metals, measured and calculated TDS;

checking blanks for evidence of contamination (see next section);

checking duplicate samples for evidence of unacceptable variation (see next section); and

checking field-collected data for completeness, and unexpected values and trends.

If results of initial data screening indicated that there were deficiencies or potential data quality issues, the analytical laboratory was contacted and re-analysis of the parameters in question in the affected samples was requested. If data were verified by the analytical laboratory, but remained questionable based on the above evaluation, qualifiers were added to affected concentrations in the project data set and they were excluded for consideration during data summary and analysis.

Similarly, historic data were assessed to identify data points that were associated with high analytical detection limits relative to recent detectable results. These data were flagged and removed from the data summary reports produced for the baseline report. Laboratories were not contacted regarding historical data as laboratory hold times for reanalysis would be exceeded.

Quality Control Data Evaluation

Field Blanks and Travel Blanks

Concentrations in field and travel blanks were considered notable if they were greater than or equal to five times the corresponding Method Detection Limit (MDL). This threshold is based on the Practical Quantitation Limit defined by the United States Environmental Protection Agency (U.S. EPA 1985), and takes into account the potential for reduced accuracy when concentrations approach or are below MDLs. This criterion was not applied to pH and conductance, which is expected to be above the laboratory-reported MDL in the deionized water used to prepare blanks.

The implications of notable results in blanks to data quality were evaluated relative to concentrations observed in surface waters sampled during the field program. The aim of this evaluation was to determine whether contamination was limited to a blank or was apparent in the corresponding water samples as well and whether it was severe enough to warrant qualifying the affected data. To address these questions, notable concentrations in blanks were interpreted as follows:

If the blank had a detectable concentration of a parameter that was higher than those in the corresponding surface water samples, it was assumed that the concentration in the blank was the result of an isolated field or lab error. In this case, the corresponding water samples were considered uncontaminated.

If the detectable concentration in the blank was less than 20% of the typical surface water concentration, the data for the corresponding water samples were considered acceptable for the parameter in question.

If the detectable concentration in a single blank was greater than 20% of the typical surface water concentration, but below those in the corresponding water samples, the water samples were considered potentially contaminated and the constituent results in question were compared to other available data to determine the significance of the potential contamination.

Duplicate Samples

Differences between concentrations measured in duplicate water samples were calculated as the relative percent difference (RPD) for each parameter. Before calculating the RPD, concentrations below the MDL were replaced with the MDL value in cases when only one of the concentrations for a given parameter was detectable. The RPD was calculated using the following formula:

RPD = (difference in concentration between duplicate samples/mean concentration) x 100

The RPD value for a given parameter was considered notable if:

it was greater than 20%; and

concentrations in one or both samples were greater than or equal to five times the MDL.

These criteria are consistent with those used by analytical laboratories for their internal QC procedures and take into account the potential for data accuracy error as parameter concentrations approach MDLs. The number of parameters with

exceedances of the assessment criteria was compared with the total number of parameters analyzed to evaluate and rate within-site variation as follows:

low, if less than 10% of the total number of parameters were notably different from one another;

moderate, if 10 to 30% of the total number of parameters were notably different from one another; or

high, if more than 30% of the total number of parameters were notably different from one another.

1.3 QUALITY CONTROL RESULTS

1.3.1 Field and Travel Blanks

Concentrations in the summer 2009 field and travel blanks were generally non-detectable or less than five times the MDL, with the exception of naphthalene in the field blank prepared August 19, 2009 (Table C-1). However, the observed naphthalene concentration in the field blank was greater than those observed in the corresponding surface water samples. The surface water samples collected in August 2009 are, therefore, considered free of contamination. No concentrations in the fall 2009 field and travel blanks were greater than five times the MDL, indicating that the corresponding field samples were free of contamination.

Concentrations of total mercury and total and dissolved chromium, copper, lead and zinc were greater than five times the MDL in the field blank prepared on February 25, 2010. However, the observed mercury concentration in the field blank was greater than those observed in the corresponding surface water samples and the observed total and dissolved lead and zinc concentrations were less than 20% of the typical surface water concentrations observed in the corresponding surface water samples. The analytical results for surface water samples collected in February 2010 are therefore unaffected by contamination for total mercury and are considered of acceptable quality for total and dissolved lead and zinc.

The total and dissolved chromium and copper concentrations observed in the February 25, 2010 field blank were greater than 20% of the typical surface water concentrations observed in the corresponding surface water samples, indicating that the surface water sample concentrations for these constituents may be affected by contamination up to the level observed in the field blank. The observed concentrations of chromium in the spring 2010 surface water samples were higher than those detectable in surface waters in the region and above water quality guideline values, indicating that the potential contamination was notable. Total and dissolved chromium results potentially affected by this contamination were flagged and interpreted with this limitation in mind. The observed concentrations of copper in the spring 2010 surface water samples were comparable to those detectable in surface waters in the region and below water quality guideline values, indicating that the potential contamination was of limited significance.

Concentrations of total bismuth and lead were greater than five times the MDL in the field blank prepared on May 17, 2010. However, the observed total bismuth and lead concentrations in the field blank were greater than those observed in the corresponding surface water samples. The surface water samples collected in spring 2010 are, therefore, considered free of contamination.

1.3.2 Duplicate Samples

Duplicate samples were collected in summer and fall 2009 and spring 2010. A duplicate sample was not collected in winter 2010 due to the limited number of accessible sampling stations with sufficient water available for collection. Based on the RPDs, notable variations observed between concentrations in duplicate samples were as follows (Table C-2):

August 14, 2009 duplicate samples at Site WC-7: none.

September 29, 2009 duplicate samples at Site WB-4: total iron.

May 19, 2010 duplicate samples at Site LC4: total aluminum.

The two parameters with notable differences account for about 1% of the total number of parameters analyzed. Based on these results, within-site variability was rated low for the 2009/2010 water quality baseline monitoring program.
