INDIANAPOLIS, Ind. – For the third day in a row, the City of Indianapolis has declared today a Knozone Air Quality Action Day.

High temperatures and little air movement means the ground-level ozone levels may be high. Ground-level ozone is the primary contributor to smog in urban areas. Smog is formed when harmful emissions from sources like cars, lawnmowers, and power plants react with sunlight.

As a result, the air quality may become unhealthy for individuals, especially active children, the elderly, and anyone suffering from lung disease or other serious health problems. Residents are encouraged to reduce prolonged or heavy exertion outdoors today.

The alert is in effect for the following counties: Marion, Bartholomew, Boone, Brown, Delaware, Hamilton, Hancock, Hendricks, Jackson, Jennings, Johnson, Madison, Monroe, Morgan and Shelby.

Residents can help prevent Knozone Action Days by reducing their contribution to ground-level ozone through these simple actions:

  • Reduce vehicle idling
  • Use active forms of transportation (walking, biking, or public transportation)
  • Fill gas tanks and mow after 7 p.m.
