Current air monitor readings across the state are rising as the Canadian wildfire plume moves from north to south. Forecast models are all pointing toward very high levels Wednesday.

Note: IDEM’s AQAD forecast is based on data from ozone air quality monitors located throughout the state. IDEM encourages residents of counties within or bordering the AQAD region(s) to heed the forecast. Air quality information for all Indiana counties can be found at SmogWatch.IN.gov. 

Some municipalities have additional open burning restrictions on AQADs. For more information, see idem.IN.gov/openburning/laws-and-rules.

IDEM encourages everyone to help reduce PM_2.5 by making changes to daily habits. You can:

• Carpool or use public transportation.
• Avoid using the drive-through and combine errands into one trip.
• Turn off engines instead of idling for long periods of time.
• Avoid using gas-powered equipment.
• Conserve energy by turning off lights and setting the air conditioner to a higher setting;
• Use propane gas instead of charcoal when grilling outdoors;
• Reminder: Indiana’s open burning laws make it illegal to burn trash and generally prohibit open burning, visit IN.gov/openburning for more information.

PM_2.5 is composed of microscopic dust, soot, and liquid that settles deep into the lungs and cannot be easily exhaled. Those people at risk are particularly vulnerable after several days of high PM_2.5 exposure. Everyone should reduce or avoid exertion and heavy work outdoors during these conditions. IDEM examines weather patterns and PM_2.5 readings to make daily air quality forecasts. Air Quality Action Days generally occur when weather conditions such as light winds, snow cover, higher humidity, and lower atmospheric inversions trap pollutants close to the ground.
