To kick-off Air Quality Awareness Week, Air Central Texas urges everyone to be aware of the increased risk of fine-particle air pollution and ground-level ozone (often referred to as smog), and to take health precautions when levels are predicted to be high. Environmental Protection Agency and Texas Commission on Environmental Quality continue to offer free resources for the public to monitor the latest air quality forecasts.

Warm summer temperatures aid formation of ground-level ozone. The current ozone standard is 0.070 parts per million (ppm) on an 8-hour average basis. Air quality alerts are issued when ozone concentrations exceed, or are predicted to exceed, this level.

"[The Austin-Round Rock region is] close to exceeding the standard for ozone. If we exceed the standard this year and designated a dirty city like the Houston, Dallas and San Antonio areas, such designation has ramifications that will last for years. More than the impact on one’s health and bank account, a dirty city designation will limit our region’s ability to grow economically and could impact transportation planning." said Travis County Judge Sarah Eckhardt.
