AMS 15 - CNRL Horizon

The Horizon Monitoring Station is located south of Canadian Natural Resources Ltd.'s Horizon site, near Fort McKay (Latitude, Longitude: 57.303689, -111.739489). The Horizon monitoring station was installed in 2007.

The Horizon station contains analyzers that continuously measure Sulphur Dioxide (SO2), Total Reduced Sulphur (TRS), Nitric Oxide(NO), Total Oxides of Nitrogen (NOx), Nitrogen Dioxide (NO2), Total Reduced Hydrocarbons (THC), Particulate Matter 2.5 (PM2.5), wind speed and direction, relative humidity, and temperature. Time integrated sampling includes Volatile Organic Compounds (VOCs) and  Particulate Matter 10 (PM10) samplers. 

For more information regarding the Anzac Air Monitoring Station, please see the station site documentation.

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.

Historical Monitoring Data

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 & Parks (AEP) in real time, or as soon as becoming aware of it.

3 - AEP uses the data and information from WBEA to follow up as appropriate.
