Local air quality affects how we live and breathe. Like the weather, it can change from day to day or even hour to hour. The U.S. Environmental Protection Agency (EPA) and others are working to make information about outdoor air quality as available to the public as information about the weather. A key tool in this effort is the Air Quality Index or AQI. USEPA and the Division of Air Quality use this standardized system to provide the public with timely and easy-to-understand information on local air quality and whether air pollution levels pose a health concern.

We do not attempt to answer all questions about air quality, however, we hope we have provided a basic explanation of air quality, air quality regulations, and the function of the DAQ.
