Air Quality Alert Issued for Central Ohio for July 23 Due to Elevated Ozone Levels

The Mid-Ohio Regional Planning Commission (MORPC) has announced an air quality alert for July 23, warning residents in Franklin, Licking, Delaware, and Fairfield counties of potentially unhealthy ozone pollution levels for sensitive individuals.

According to MORPC’s statement released on July 22, the Air Quality Index (AQI) is expected to reach 101, placing it in the “unhealthy for sensitive groups” category. The air quality scale, which runs from 0 to 500, uses this number to indicate elevated pollution levels.

The increase in ozone pollution is attributed to a ridge of high pressure that will reduce atmospheric mixing. Coupled with sunny skies, high temperatures in the 90s, and lingering wildfire smoke, these conditions are expected to intensify ozone formation and particle pollution across the Central Ohio region.

MORPC advises sensitive populations including children, the elderly, and individuals with asthma or chronic respiratory conditions like COPD to minimize outdoor exposure, especially during morning hours.
