Air quality study in Yorkton  
The Great Plains Air Zone continuously monitors air within the geographic boundaries of our area.  One of the monitoring stations is located in Yorkton, Saskatchewan where GPAZ has been collecting air quality data and making it public on our website since May 2017. Periodically, we have detected levels of Hydrogen sulfide (H2S) that are above the air quality objective, which is approximately .011 parts per million (ppm). At this level, people may notice an unpleasant smell but risks to health don't come until a much higher level is reached, near 1 part per million (ppm) (which is almost 1000 times higher than the readings collected in Yorkton). Even though there is not a risk to human health in Yorkton, GPAZ and the Ministry of Environment conducted a study in the summer of 2017 to better understand the readings and to locate sources of Hydrogen Sulfide emissions near the city.

This is a map of the area North West of Yorkton, Saskatchewan. The dots are study locations. 





In the summer of 2017, the Great Plains Air Zone and Saskatchewan Ministry of Environment cooperated to monitor and interpret air quality data from the Yorkton area.  Continuous air quality monitoring for significant air pollutants is being collected 365 days a year by the Great Plains Air Zone and communicated the the public on its website www.gpaz.org
During calm evenings Hydrogen sulfide (H2S) levels reached or exceeded the Saskatchewan ambient air quality objective a number of times at an amount that resulted in increased unpleasant odours but not health concerns.  As a result of this information the Saskatchewan Ministry of Environment conducted continuous monitoring from June 14 to August 30th and more focused mobile monitoring for H2S on August 29th/30th.  The ambient air quality standard for H2S was exceeded at a level that would cause unpleasant odours, but not negative health effects.
Based on the measurements taken at the continuous stationary sites and using mobile monitoring, it appears that H2S is coming from a number of natural sloughs as well as from an industrial area of Yorkton.  When the weather conditions are just right (calm winds, evening inversion conditions) the combined levels can reach a level that is above the standard of .011 parts per million (ppm).  At this level, it may result in an increase in people noticing unpleasant odours but it is not a level that would start to cause health impacts, which is 1 part per million (ppm). For more information on the safe levels of exposure to H2S, please click here: http://work.alberta.ca/documents/WHS-PUB-CH029.pdf  Sloughs are a source of H2S because it is created when vegetation rots where there is no air. As plants rot underwater, H2S is released.
