mobile monitoring

WBEA’s Mobile Air Monitoring unit is used to temporarily record air quality at designated locations in the Wood Buffalo region. The mobile unit can also be dispatched during air quality events that require immediate air monitoring in a specific area or community.

The Mobile Air Monitoring unit contains analyzers that continuously measure SO2, H2S, THC, NH3, NO, NO2, NOX, PM 2.5, wind speed and direction, and temperature.

Our H2S analyzers are based on a scientific measurement principle (fluorescence after thermal oxidation) specified by AENV in the Air Monitoring Directive (AMD). The H2S analyzers also oxidize other sulphur compounds that are fluoresced and read as H2S.

Within the WBEA network, H2S is measured at some stations and Total Reduced Sulphur (TRS) is measured at other stations. TRS analyzers use the same measurement principle (fluorescence after thermal oxidation) as H2S analyzers, but operate at a different oxidizing temperature. The choice of analyzer for each station is mandated by AENV Reporting Requirements in the Approvals to Operate a Facility and by the AMD.

The Alberta Ambient Air Quality Objective (AAAQO) for H2S is based on odour perception.

All air quality monitoring data displayed on this site by the Wood Buffalo Environmental Association is directly from monitoring equipment output signals. Displayed data is generally indicative of ambient conditions, however, it has not been reviewed, validated, nor processed for baseline drift and other fluctuations by qualified technicians. Final processed and validated data values may vary from values displayed on this site. A displayed value of 'n/d' indicates air monitoring data is not available at the corresponding time due to scheduled maintenance and/or instrument calibration. Charted data is locked to the range of the analyzer by default, and can be unlocked by the appropriate control. To access quality-checked and validated historical data, please visit the Casa Data Warehouse: www.casadata.org

PLEASE NOTE: When ambient concentrations of any pollutant WBEA measures exceeds the Alberta Ambient Air Quality Objective, WBEA has an immediate Reporting Protocol that is put into action. WBEA analyzers continuously monitor ambient air, and in the event of an exceedence the following steps are taken:

1 - The data collection system automatically sends out alarm notifications to WBEA personnel and an independent third party alarm monitoring company. 

2 - The alarm company acknowledges the incoming alarm and reports the data and supporting information such as wind conditions, locations, time, etc, to Alberta Environment in real time, or as soon as becoming aware of it.

3 - As the provincial regulator, Alberta Environment uses the data and information from WBEA to follow up as appropriate.
