A nearly 90,000-acre wildfire is affecting air quality across the state, with the Colorado Department of Public Health and Environment issuing an Ozone Action Day Alert for several counties, including Douglas, Jefferson, Denver, and others [^1]. The alert, which is in effect from 4:00 PM Sunday, July 5, to 4:00 PM Monday, July 6, warns of ozone levels in the Moderate to Unhealthy for Sensitive Groups range due to hot and sunny weather [^2]. [The Aspen Acres fire](https://foco-observer.com/colorado/wildfire/aspen-acres/) (southwest of Pueblo) is one of the sources of the air quality concerns, it has grown to 89,054 acres as of July 5, with 14% containment, and is still considered active [^1]. Despite the fire being in the southern part of the state, local residents are advised to reduce prolonged or heavy outdoor exertion, especially those with lung disease, such as asthma, and to limit driving gas and diesel-powered vehicles to help reduce ozone pollution [^2].
