The information collected is anonymous and will be used for research purposes only. The Wood Buffalo Environmental Association (WBEA) monitors air quality in the Regional Municipality of Wood Buffalo (RMWB). The WBEA is asking the public to participate in its Community Odour Monitoring Program (COMP), which seeks to gain a better understanding on how odour events in the region relate to our ambient air quality. The information you provide will populate a database that will be compared to the data collected at our ambient air monitoring stations throughout the RMWB. If you would like to make a complaint to the Alberta Government about an odour you are experiencing, please call their 24-hour Energy & Environmental Response Line at 1-800-222-6514.
