LOUISVILLE, Ky. (WDRB) -- An Air Quality Alert has been declared for Louisville and several counties in southern Indiana on Wednesday, July 19. 
The Louisville Metro Air Pollution Control District (APCD) and the Indiana Department of Environmental Management (IDEM) are forecasting high ozone levels in the unhealthy range. 

Ground-level ozone is formed when sunlight and hot weather bake vehicle exhaust, factory emissions and gasoline vapors. Ozone in the upper atmosphere blocks ultraviolet radiation, but ozone near the ground is a lung irritant that can cause coughing and breathing difficulties. 

The alert means sensitive groups like  children, seniors, active people, and anyone with heart and/or lung ailments should take precautions and remain indoors.  If they do go outside, sensitive groups should avoid exertion and heavy work.

Louisville is included in the alert along with several counties in Indiana including Brown, Clark, Floyd, Harrison, Jackson, Jefferson, Scott, and Washington. 

Help the air during Air Quality Alerts by doing the following: 

  • Walk, bike, carpool or use public transportation.
  • Avoid using the drive-through and combine errands into one trip.
  • Avoid refueling your vehicle or using gasoline-powered lawn equipment until after 7 p.m.
  • Turn off your engine when idling for more than 30 seconds.
  • Conserve energy by turning off lights or setting the air conditioner to 75 degrees or above.
  • Check on neighbors with breathing problems.
  • Put off lawn mowing until the alert ends.
