From January through March 2023, Fort Air Partnership (FAP) recorded 12,716 hours of air monitoring data for use in calculating the Air Quality Health Index (AQHI) at seven stations in our Airshed.
- 10,157 (or 79.9%) of the hours were of low-risk AQHI.
- 2,249 (or 19.2%) of the hours were moderate-risk AQHI.
- 110 (or .009%) were high or very high-risk AQHI.
Summary of Exceedances
There were 59 one-hour exceedances of the Alberta Ambient Air Quality Objectives (AAAQO), 30 exceedances of the 24-hour, and six (6) exceedances of the three-day objective in the first three months of 2023.
Wintertime temperature inversions caused the majority of the exceedances. Three exceedances were caused by industry coupled with a wintertime temperature inversion.
Air quality measurements are compared continuously to both one and 24-hour AAAQOs. An exceedance of an AAAQO is reported to the Alberta Government, and the likely cause of the exceedance is investigated.
