The Idaho Department of Environmental Quality issued an air quality advisory for Ada, Canyon, Gem, Payette, and Washington counties, warning residents of unhealthy conditions through 3 p.m. MDT Wednesday, July 22. The advisory alerts residents across the Treasure Valley and surrounding regions to take precautions as air quality deteriorates due to increased particulate matter and smoke.
Children, older adults, and individuals with respiratory or heart conditions face elevated health risks during the advisory period. The DEQ recommends that these vulnerable populations limit prolonged or strenuous outdoor activity until air quality improves. Residents in Ada County and neighboring jurisdictions should monitor conditions closely and adjust outdoor plans accordingly.
Open burning is prohibited throughout the affected counties under Idaho air quality regulations during the advisory. The restriction aims to prevent further degradation of air quality during a period when the Air Quality Index is forecast to reach unhealthy levels.
The DEQ Boise Regional Office can provide additional information at 208-373-0550. Residents seeking real-time air quality data can check the agency’s website for current conditions and forecasts specific to their location.
Air quality advisories are common during summer months in Idaho when weather patterns trap smoke from wildfires and other sources. Planning outdoor events and activities requires checking current air quality forecasts before committing to extended time outside.
