July’s air quality hasn’t been great around Northern Utah, and it could get worse in the coming week. 

Both Weber and Davis counties have spent most of the month under mandatory air quality actions from the Utah Department of Environmental Quality.

In both counties, all but five days so far this month have had unhealthy air for sensitive groups, and all but three days had a mandatory air quality action, according to the UDEQ.

Two of the three days without a mandatory air quality action were Wednesday and Thursday of this week. Both days saw decreases in levels of micrograms of pollution per cubic meter, according to UDEQ’s website.

However, local air quality could take a turn for the worse in the next few days, as legal fireworks will once again start Friday and ending Thursday, July 27.

Over the Fourth of July, Weber County’s air pollution dramatically spiked to 790 micrograms per cubic meter. The airborne pollution in Weber County was over 10 times worse than what it was in nearby places. 

Davis County’s highest level during the July 4 holiday was 77 micrograms per cubic meter, while Salt Lake County reached only 29 micrograms per cubic meter. 

Utah’s first round of legal firework season started on July 1 and ended July 7. The next and final round of legal fireworks starts Friday and will last until July 27.

Fireworks can be used from 11 a.m. to 11 p.m. during that time period. On Pioneer Day, Monday, July 24, firework use is extended to midnight. 

If you choose to use fireworks in the coming week, be sure to check and see what is allowed in your Weber or Davis county city.
