Alberta Environment conducts mobile air quality surveys each year as part of its air quality monitoring program. These surveys are unannounced and use the department’s mobile air monitoring program (MAML).

Air quality monitoring northwest of the town of Brooks was initiated by concerns of fugitive emissions from feedlots, wastewater treatment lagoons and irrigation operations in the area. The largest of these facilities is Lakeside Farm Industry (which includes Lakeside feedlot). As an integrated agribusiness, Lakeside Farm Industry is involved in feeding, slaughtering, processing cattle, farming and irrigating land for silage. Previous surveys in the area showed that the highest ammonia, hydrogen sulphide, hydrocarbons and particulate matter concentrations were measured downwind of Lakeside feedlot.

A Canadian National (CN) rail yard is located just south of the neighbourhood of Calder, in Edmonton. The yard handles on average 50 trains daily and operates 24 hours a day, throughout the year. Residence of Calder neighbourhood had concerns with diesel fume impacts on the air quality in the area, especially from trains that are left to idle for extended periods of time. To assess the quality of air in the Calder neighbourhood, Alberta Environment conducted mobile air monitoring surveys in the winter and summer of 2004 and the winter of 2005. The surveys were conducted on days with light wind. Monitoring locations were selected such that samples were collected upwind and downwind of the Calder yard. The surveys were unannounced and used the department’s Mobile Air Monitoring Laboratory (MAML). The MAML provides an air quality “snap shot” in time and space and thus was ideal for the type of monitoring conducted in this study.

As part of its air quality monitoring program, Alberta Environment conducts unannounced air quality surveys through out the province. Such a survey was conducted in the area of Tolko industries for two days in December of 2005 and two days in March of 2006. Tolko industries, located west of High Prairie, produce Oriented Strand Board (OSB) panels. OSB panels are produced from wood strands, flakes and wafers that are bonded using a synthetic resin. The process involves high temperature and pressure, during which pollutants may be released into the atmosphere; this would occur in addition to any fugitive emissions from the facility. The objectives of this study included the quantification of selected pollutants in the proximity of Tolko Industries and comparison of measured concentrations to Alberta’s Ambient Air Quality Objectives.

Data contained on the CASA Web site is archived data and may be at least one-month old. More current air quality data is available at individual organization's Web sites. At the present time, current air quality data is available for stations operated by Alberta Environment, the Wood Buffalo Environmental Association, the Parkland Airshed Management Zone, the West Central Airshed Society, the Fort Air Partnership, the Palliser Airshed Society, and the Peace Airshed Zone Association.
