About

The WBEA’s Community Odour Monitoring
Program (COMP)

The Wood Buffalo Environmental Association (WBEA) monitors the air quality in the Regional Municipality of Wood Buffalo (RMWB) 24 hours a day, 365 days a year, through a network of 30 ambient air monitoring stations. Each station contains multiple analyzers that continuously measure the concentration of different pollutants, along with meteorological parameters such as wind speed, wind direction, temperature, humidity, and atmospheric pressure.

The WBEA was repeatedly approached by members of different communities in the RMWB about the odours they experienced. Currently, analyzers can measure the concentration of specific pollutants or groups of pollutants, but it cannot measure if an odour is present or how strong an odour would be.

The WBEA created an App which allows people to directly provide information about the odours they experience. The App allows the WBEA to connect the information people provide about odours to the ambient air data being collected at WBEA air monitoring stations.

The App was launched in September 2017. This is the second annual report released by the WBEA and covers the year of 2019. Last year's report can be found here.

COMP App Information

Below is an explanation of the information collected in the App and then used by the WBEA to compare with the ambient air data collected at each station. The WBEA wants to develop an understanding of the odours people are experiencing and has provided categories for users to describe their experience.

Odour Type

Once an odour is at a concentration high enough to be detected by an individual, the type of odour can be described. The odour type is completely subjective based on the person, and within the COMP App there are currently seven options: Ammonia/Cat Urine, Asphalt/Tar, Fecal/Septic, Fuel/Solvent, Smoke/Burnt, Sulphur/Rotten Eggs, and Other. Users are to select the odour type that best describes, to them, the odour they are experiencing.

Odour Intensity

The intensity of an odour is the perceived strength of the odour that is being experienced by the individual and is not necessarily related to its concentration. For example, a particularly pungent odour at a low concentration may be perceived to be more intense than a less pungent substance at a higher concentration. The intensity may also depend on the individual’s sensitivity to odours.

Activity

Activity is included so that users can provide information about what they are doing when they encounter the odour; they can indicate whether they are indoors, outdoors, or driving.

Duration of Odour

Duration of odour is the length of time the user experiences the odour. This is to provide context about whether someone had a brief encounter with an odour, or experienced a long-lasting, persistent smell.

Location of Odour

It is necessary to collect the position where the user experienced the odour so that the WBEA can compare the data to the closest ambient air monitoring station. It is also used to compare multiple observations to each other if they are submitted from the same area.

Time Odour Detected

To compare odours experienced by users to the data the WBEA collects at their ambient air monitoring stations, the WBEA needs to know the date and time the user encountered the odour.

Energy & Environmental Response Reference Number (Optional)

If an odour is particularly strong and a user wants to file a report with the Alberta Government, they can call their 24-hour Energy & Environmental Response line, whose number is listed on the main page of the App. When a user files a report, they will be provided with a Reference Number. The user can enter that Reference Number into the App, to show a report was filed. It is an optional field.

About Odours

Some humans have a sensitive sense of smell and can detect odours even when chemicals are present in very low concentrations. Most odours that occur in ambient air (i.e., outdoor air that is not on an industrial site) are caused by very small traces of chemicals. The ability to smell a particular odour varies from person to person due to variations in their sensitivity and depends on the concentration of the pollutant.

Meteorology and Odours

Atmospheric conditions and weather can affect pollutants that have been released into the air. As an air pollutant, which may or may not have an odour, is transported from the source from which it was emitted to a community, the pollutant mixes into the surrounding air so that it arrives at a much lower concentration than it was when it initially emitted. The concentration of an air pollutant that reaches a community is due to many variables, including the amount of the pollutant released at the source, the height of the source, the distance from the source to the community, the surrounding topography, and local weather conditions. The most important weather influences are wind speed, wind direction, precipitation, sunlight, and the amount of turbulence in the atmosphere. Generally, strong winds disperse pollutants, whereas light winds can allow pollutants to build up over an area. The wind direction determines where emissions are transported.

Odour Causing Compounds

Hydrogen Sulphide & Total Reduced Sulphur Compounds

Total Reduced Sulphurs (TRS) are a large group of sulphur-containing compounds, including hydrogen sulphide (H2S) and mercaptans. Many TRS compounds can produce offensive odours at low concentrations. Due to the sulphur, TRS compounds tend to have a smell similar to rotten eggs. Concentrations of H2S and TRS are measured in parts per billion (ppb).

Non-Methane Hydrocarbons (NMHC)

Hydrocarbons are a large group of compounds, which are either measured as total hydrocarbons (THC), or due to new monitoring technology, can be split into methane (a single carbon atom = C1) and non-methane hydrocarbons (the sum of all C2 to C12 hydrocarbon compounds). Methane itself does not have an odour – a smelly chemical is usually added to methane to allow you to smell it when you are using Natural Gas. Methane from industrial combustion does not have the additive, so will not have an odour. Methane is also present naturally in the air, at a concentration of about 1.8 parts per million (ppm).

However, many other hydrocarbons besides methane, called the “non-methane hydrocarbon” (NMHC) portion, may have odours and may have them at very low concentrations. Depending on the substance, they may smell like rotten cabbage, smelly socks, or eggs. Concentrations of NMHC are measured in parts per million (ppm).

Sulphur Dioxide (SO2)

The WBEA monitors sulphur dioxide (SO2) due to sulphur emissions from the oil sands industry. SO2 is emitted when fuel containing sulphur is combusted. Generally, concentrations of SO2 are not high enough for people to smell it. However, we use ambient air concentrations of SO2 to indicate the potential presence of an industrial plume. That industrial plume may contain other, more odorous compounds which may be the cause of the odours people are experiencing. This can help distinguish the industrial odours from other local sources like construction, road work, and sewage plants. Concentrations of SO2 are measured in parts per billion (ppb).

WBEA Air Monitoring Stations Map

Air Monitoring Stations These are all the Air Monitoring Stations the WBEA operates.

Community Air Monitoring Stations The Community Air Monitoring Stations are the stations the WBEA operates within the communities of the RMWB. The WBEA used the data from community stations to compare to the submitted COMP odour observations.

Summary of Observations:

In 2019, a total of 415 odour observations were submitted from 95 unique users. The bar below shows the observations sorted by the different information users submitted to the app about the odours they experienced. The most common odour type identified was ammonia (120), followed closely by asphalt (114). Most odours were ranked highly on the 1-10 intensity scale, with 89 odours receiving a ‘strong’ intensity, while almost half of odours (191) were reported to have a long (>60 minutes) duration. Odours were mostly experienced during daylight hours, and during all days of the week. In 2019, the most odour observations were submitted during the months of July to September. This could possibly be because more people are outside during these months and are more likely to notice whether odours are present. For activity type, most users reported they were outdoors (217) when they experienced the odour, followed by driving (152). For Location, 206 observations were submitted from the Fort McMurray area, 154 from Highway 63/Industrial area North of Fort McMurray, 41 from Fort McKay, 8 from Fort Chipewyan, 5 from Anzac, and 1 from Conklin. There were no observations submitted from Janvier in 2019.

Community Breakdown

This section provides the breakdown of odour observations received in each community within the Regional Municipality of Wood Buffalo. The map shows the location of all the observations received between January 2019-December 2019. The histograms show the distribution of the number of observations received at different ambient concentrations of the pollutants of interest. For the most part, observations are submitted when ambient concentrations are low.

The last part of the Community Breakdown is the pollution and wind roses; they’re used to show the prevailing wind direction (wind rose) when observations were submitted, and the prevailing wind direction plus ambient concentration of pollutants (pollution rose) when observations were submitted.

Odour Event Days

Odour event days are days that have at least four odour observations submitted from the same geographical location, by different users. In 2019, there were eight days that met these criteria, all of which were in Fort McMurray. Of the eight events, seven had indicators of an industrial plume, and five were on days that also had exceedances of the 1-hour Alberta Ambient Air Quality Objective (AAAQOs) for H2S at an air monitoring station North of Fort McMurray. Select a day below for the details of each odour event day.

Event Day

June 23, 2019

On June 23, 2019, four odour observations were submitted from three different users; three from the Timberlea and one from Thickwood Heights. Two of the observations reported the odour type as ‘Asphalt’, one as ‘Sulphur, and one as ‘Fuel’.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea.

Three of the observations were submitted between the hours of 08:20 and 09:30 with one later report at 20:53. During the times of the three earlier observations, at Patricia McInnes TRS concentrations increased at almost 2 ppb, SO2 increased from 0.3 ppb to 12 ppb at Patricia McInnes, and NMHC levels increased from zero to 0.2 ppm. These were some of the highest NMHC concentrations observed at the site for the year. The 20:53 observation was also associated with an increase in TRS, SO2, and NMHC at Patricia McInnes AMS.

Wind direction was from the north-northwest and north during the times of odour observations. Wind speeds were moderate and in the range of 10 to 15 km/h.

There was one exceedance of the 1-hour Alberta Ambient Air Quality Objective (AAAQO) for H2S on June 23, 2019, which occurred at 05:00 at an air monitoring station North of Fort McMurray.

Conclusion:

Increase in the parameters SO2, TRS and NMHC did coincide with observations of odours and were likely an indicator of an industrial plume which also could be carrying other odour-causing compounds. NMHC concentrations were very high for this period. The observations coincided with wind direction from the north (the direction of the industrial facilities) and moderate wind speeds.

August 5, 2019

On August 5, 2019, ten odour observations were submitted from seven different users: seven from the Timberlea area and three from downtown. Four of the observations reported the odour type as ‘Ammonia’, three reported the odour type as ‘Asphalt’ and three reported as ‘Other’.

The air monitoring station (AMS) closest to the Timberlea observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

Eight of the observations were submitted between the hours of 08:30 and 11:20 with two later reports between 20:30 and 22:00. TRS concentrations increased at Patricia McInnes going from 0.3 ppb to 1.8 ppb at 10:00. At Athabasca Valley TRS concentrations went from 0.3 to 1.8 ppb. SO2 also increased moderately during this period from 0.3 ppb at both sites to 4.1 ppb at Patricia McInnes and 2.1 ppb at Athabasca Valley. NMHC levels increased from zero to reach 0.3 ppm at both sites. These were some of the highest NMHC concentrations observed at either site for the year. The 20:30 to 22:00 observation period was also associated with an increase in TRS, SO2 and NMHC.

Wind direction was from the north, north-northwest and west-northwest during the times of odour observations. Wind speeds were moderate and in the range of 10 to 15 km/h.

There were two exceedances of the 1-hour Alberta Ambient Air Quality Objective (AAAQO) for H2S on August 5, 2019. They occurred at 21:00 and 22:00 at an air monitoring station North of Fort McMurray.

Conclusion:

The increase in SO2, TRS and NMHC did coincide with observations of odours and were likely an indicator of an industrial plume which could be carrying other odour-causing compounds. NMHC concentrations were very high for this period. The observations coincided with wind direction from the north (the direction of the industrial facilities) and moderate wind speeds.

August 26, 2019

On August 26, 2019, twelve odour observations were submitted from twelve different users: six from Timberlea, four from Thickwood, and two from downtown. Ten of the observations reported the odour type as ‘Ammonia’, one reported the odour type as ‘Asphalt’, and one reported as ‘Sulphur’.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

The observations were submitted between the hours of 09:50 and 21:20 with eight reports between 12:17 and 14:40. TRS concentrations increased slightly at Patricia McInnes going from 0.4 ppb at 11:00 to 0.8 ppb at 14:00. At Athabasca Valley TRS concentrations increased from 0.8 to 1.6 ppb. SO2 also increased during this period from 0.3 ppb at both sites, reaching 11 ppb at Patricia McInnes and 8 ppb at Athabasca Valley. During the 11:00 to 14:00 time period NMHC levels increased from zero at both sites to 0.17 ppm at Patricia McInnes and 0.10 ppm at Athabasca Valley.

Wind direction was from the north during the times of odour observations. At Patricia McInnes wind direction was northwest at 09:00 with light wind and at 12:00 it was from the north with a wind speed of 14 km/h.

There were six exceedances of the 1-hour Alberta Ambient Air Quality Objective (AAAQO) for H2S on August 26, 2019. They occurred at 06:00, 17:00, 18:00, 19:00, and 20:00 at an air monitoring station North of Fort McMurray.

Conclusion:

The increase in SO2, TRS and NMHC did coincide with observations of odours and were likely an indicator of an industrial plume which could be carrying other odour-causing compounds. The observations coincided with a wind direction change from northwest to north (the direction of the industrial facilities) and an increase in wind speeds.

August 29, 2019

On August 29, 2019 five odour observations were submitted from five users: three from the Timberlea area, one from downtown, and one from the airport. One of the observations reported the odour type as ‘Ammonia’, one reported the odour type as ‘Asphalt’, one reported ‘Fecal’ and two as ‘Other’. There were also three reports from the highway/industrial area on this date with two reporting a ‘Sulphur’ odour and one ‘Ammonia’.

The air monitoring station (AMS) closest to the Timberlea observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

The observations were submitted on five different hours between the hours of 00:00 to 19:00. At the time of the 10:55 odour observations winds were from the south and south-southwest but there was a spike in SO2 concentration at both sites with concentrations reaching 18 ppb at Athabasca Valley. TRS concentrations at Patricia McInnes were near background for the entire day but reached 3 ppb at Athabasca Valley at 11:00. NMHC levels were near zero at both sites during the period.

The earlier odour observations were associated with south and south-southwest wind direction. Winds did switch to the north around noon and the later odour observations were associated with northerly winds. Wind speeds were less than 10 km/h at both sites for the day.

There were no exceedances of the Alberta Ambient Air Quality Objectives (AAAQOs) for H2S on August 29, 2019.

Conclusion:

It is not clear what source(s) was responsible for the increase in SO2 and TRS (Athabasca Valley) with winds from the south. This day is difficult to characterize because of the diverse nature of the reports.

August 30, 2019

On August 30, 2019 seven odour observations were submitted from seven different users: three from the Timberlea, one from Thickwood, and three from downtown. Two of the observations reported the odour type as ‘Ammonia’, three reported the odour type as ‘Asphalt’, one as ‘Sulphur’, and one as ‘Fuel’. There were also four reports from the highway/industrial area on this date with all reporting an ‘Asphalt’ odour.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

The observations were submitted between the hours of 15:00 and 17:00 with five coming between 15:20 and 15:50. TRS concentrations at both monitoring sites increased from less than 0.5 ppb to 1.3 ppb at Patricia McInnes and to 3.4 ppb at Athabasca Valley. SO2 concentrations also increased from near zero to 15 ppb at Athabasca Valley and 6 ppb at Patricia McInnes. NMHC levels increased slightly from zero to 0.2 ppm at both sites during the same period. Elevated concentrations of TRS, SO2 and NMHC persisted for the rest of the day at both sites but no further odour observations were received.

Winds were from the west-southwest prior to the observations and switched to north and north-northeast at both sites during the reporting period with moderate wind speeds of 13 to 19 km/h.

There was one exceedance of the 1-hour Alberta Ambient Air Quality Objective (AAAQO) for H2S on August 30, 2019, which occurred at 23:00 at an air monitoring station North of Fort McMurray.

Conclusion:

Increase in the parameters SO2, TRS and NMHC did coincide with observations of odours and were likely an indicator of an industrial plume which could be carrying other odour-causing compounds. The observations coincided with a wind direction change from west-southwest to north (the direction of the industrial facilities) with moderate wind speeds.

September 5, 2019

On September 5, 2019 seven odour observations were submitted from seven different users: two from Timberlea, four from Thickwood, and one from downtown. Five of the observations reported the odour type as ‘Ammonia’, one reported the odour type as ‘Asphalt’ and one as ‘Sulphur’.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

The observations were submitted between the hours of 18:00 and 21:00 with six coming between 20:00 and 21:00. TRS concentrations at both monitoring sites increased from less than 0.5 ppb to over 1 ppb at Patricia McInnes and to 2.5 ppb at Athabasca Valley. SO2 concentrations also increased from near zero to 9 ppb at Athabasca Valley and to 2.8 ppb at Patricia McInnes. NMHC levels were near zero at both sites during the period.

Winds were from the west prior to the observations and switched to north and north-northwest at both sites during the reporting period with strong wind speeds of more than 20 km/h.

There were two exceedances of the 1-hour Alberta Ambient Air Quality Objective (AAAQO) for H2S on September 5, 2019. They occurred at 19:00 and 23:00 at an air monitoring station North of Fort McMurray.

Conclusion:

Increase in the parameters SO2 and TRS did coincide with observations of odours and were likely an indicator of an industrial plume which could be carrying other odour-causing compounds. The observations coincided with a wind direction change from west to north (the direction of the industrial facilities) with strong wind speeds.

September 17, 2019

On September 17, 2019 nine odour observations were submitted from eight different users: three from Timberlea, five from Thickwood, and one from Beacon Hill. Eight of the observations reported the odour type as ‘Ammonia’, and one reported it as ‘Fuel’.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS, located downtown, is the closest to Beacon Hill.

The observations were submitted between the hours of 15:00 and 19:00, with five submitted between 16:00 and 17:00. SO2 concentrations at both monitoring sites increased from less than 1 ppb to over 7 ppb. TRS concentrations showed little change at Patricia McInnes (~0.5 ppb) but increased from 0.3 to 2.2 ppb at Athabasca Valley during this period. NMHC levels were near zero at both sites during the period. Winds were from the north prior to the observations at both sites with wind speeds less than 10 km/h.

There were no exceedances of any Alberta Ambient Air Quality Objectives (AAAQOs) for H2S on August 29, 2019.

Conclusion:

Increases in the parameters SO2 and TRS, at Athabasca Valley, did coincide with observations of odours and were likely an indicator of an industrial plume which also could be carrying other odour-causing compounds. Winds were light and blowing from the north (the direction of industrial facilities).

October 18, 2019

On October 18, 2019, seven odour observations were submitted from six different users; one from downtown, one from Timberlea, and five from Thickwood Heights. The earliest observation at 08:30 reported the odour as ‘Fuel’, the two 14:00 observations reported the odour as ‘Fecal’ and the four observations between 16:50 and 18:40 reported the odour type as ‘Asphalt’.

The air monitoring station (AMS) closest to the Timberlea and Thickwood observations is Patricia McInnes AMS in Timberlea, while Athabasca Valley AMS is downtown.

From 15:00 to 18:00, TRS concentrations increased from background to 2.8 ppb at Patricia McInnes AMS and to 1.7 ppb at Athabasca Valley AMS. SO2 also increased during this period from near zero at both sites to 3 ppb at Patricia McInnes AMS and 2.4 ppb at Athabasca Valley AMS. NMHC levels briefly spiked at Athabasca Valley AMS to 0.5 ppm at 10:00 and increased between 16:00-18:00 to 0.2 ppm. NMHC levels were low at Patricia McInnes for the entire period.

Wind direction was from the north-northwest and north during the times of afternoon odour observations. Wind speeds were light to moderate and less than 10 km/h.

There were no exceedances of the Alberta Ambient Air Quality Objectives (AAAQOs) for H2S on October 18, 2019.

Conclusion:

The 16:50 to 18:40 odour observations, all characterized as “asphalt” were associated with an increase in the parameters SO2, TRS and NMHC and were likely an indicator of an industrial plume which could be carrying other odour-causing compounds. The observations coincided with a wind direction from the north (the direction of the industrial facilities) and moderate wind speeds. The 08:30 observation described the odour as ‘fuel’ and wind direction was from the southwest, while the 14:00 observations characterized the odour as ‘Fecal’ and wind direction was from northwest. It is likely these earlier observations were a result of a non-industrial source.
