ozone

As ozone season begins, the region has already exceeded federal air quality standards. Environmental advocates are urging residents to change small behaviors in their lives while cities work to fix the problem.

Leaders say they need to take critical steps to address poor air quality in the region.

Ozone levels in Dallas-Fort Worth are the highest they’ve been in the past three years.

As of July 18, the region reported 17 days that ground-level ozone, or smog, exceeded levels considered healthy for all populations. In 2023, the area reported 13 ozone air quality alerts.

Given the number of times Dr. Jeffrey Jarvis saw highway signs blaring “OZONE ALERT” this summer, they may as well have been broken, he said.
