Check for Ozone Action Days

Introduction to Air Quality

          Air quality affects all of those living in the San Antonio region in one way or another. It concerns most citizens by way of health effects. The air quality issue for the San Antonio region has been that of ground-level ozone. Ground-level ozone is created when light winds, heat, and sunshine together with an adequate combination of pollutants (nitrogen oxides and volatile organic compounds); cause a chemical reaction that produces ozone pollution. Vehicle use contributes greatly to our ground level ozone issue. Please remember the things we all can do to help reduce ground-level ozone.
