The award-winning Ozone Alert! Program brings citizens, business, industry and government together to voluntarily reduce ozone-forming emissions on days vulnerable to high ozone levels.

This Air Quality Index (AQI) reflects Ozone. It also reflects the health concerns of and corresponds to the EPA’s national pollutant standard. AQI’s higher than 100 generally signify air quality unhealthy for sensitive groups and an exceedance of the pollutant’s standard.

Ozone is Good Up High but Bad Nearby.

Ozone is a gas found in the air we breathe and can be good or bad, depending where it occurs:

  • Good ozone is present naturally in the Earth’s upper atmosphere—approximately 6 to 30 miles above the Earth’s surface. This natural ozone shields us from the sun’s harmful ultraviolet rays.
  • Bad ozone forms near the ground when pollutants (emitted by sources such as cars, power plants, industrial boilers, refineries and chemical plants) react chemically in sunlight. Ozone pollution is more likely to form during warmer months. This is when the weather conditions normally needed to form ground-level ozone—lots of sun—occur.

Check back regularly for current ozone levels to protect your health and help us stay below the national standards.
