Results are in for air quality in the region.
Over the first six months of 2018, Fort Saskatchewan had the worst air quality in the heartland. There was 858 hours of moderate risk air quailty and six hours of high risk.
"We did see a higher percent of time in the moderate category compared to the first six months of last year," said Fort Air Partnership (FAP) executive director Nadine Blaney.
From January 1 to June 30 in 2017, the overall air quality was at low risk readings 93 per cent of the time. During the same time in 2018, the overall region was at low risk readings 79 per cent of the time.
The difference can largely be attributed to wintertime inversions in March. A wintertime inversion is a weather condition where cold air, along with pollutants, is trapped near the ground by a layer of warm air.
Bruderheim, followed closely by Lamont County, had the most time with low risk readings. Gibbons has the most amount of high risk air quality with 12 hours.
