Air Quality - Ozone 101
Ozone is the primary air pollutant of concern in the Austin-Round Rock Metropolitan Statistical Area (A-RR MSA), which includes Bastrop, Caldwell, Hays, Travis, and Williamson Counties. Air quality readings taken from monitors within the A-RR MSA indicate that ozone levels have exceeded federal standards on numerous occasions. High ozone levels can negatively affect asthma and other upper respiratory illnesses. At-risk groups include children, the elderly, and those who work or exercise outdoors.
Information on ground-level ozone sources and how it is formed, the current status of ozone levels in the region, and initiatives being taken in Central Texas to maintain good air quality can be found at the following links:
