Association continues to monitor air quality


The Southeast Saskatchewan Airshed Association (SESAA) is continuing with its efforts to track air quality in this region.

SESAA is a non-profit organization of public, industry, government, and non-government members that was incorporated in 2005. The organization's goal is to collect credible, scientifically defensible air quality data for the southeast region, and to make this data available to stakeholders.

"SESAA had a very good year in 2013 and now has six air monitoring stations operating in the region, providing real-time data," said executive director Terry Gibson.

The existing monitoring stations are located near Glen Ewen, Stoughton, Wauchope, Wawota, Weyburn and Esterhazy. Data from the monitoring stations are posted on the organization's website.

Information from the six monitoring stations on August 13, for example, showed that air quality was listed as good in all six areas. Readings on the air quality index ranged from nine at Esterhazy to 13 at Weyburn. A reading between zero and 75 is classified as "good."

The report for Stoughton, for example, stated that there weren't any known harmful effects to soil, water, vegetation, animals, visibility or human health. Different components of air quality are also tracked at each station.

The organization recently agreed to operate the SaskPower continuous air monitoring station in Estevan.

"The addition to the SaskPower site, and the new instrument provided by the Ministry of the Economy will expand the network to a total of eight continuous air monitoring stations," said Gibson. "This will provide a very good understanding of the ambient air quality in the region."

The site of the next station will be determined by SESAA's science committee.

Gibson said they haven't had any surprises in the information from the monitoring stations. The instruments are set up to capture data for specific parameters, and he said they have a pretty good idea of what to expect.
