Air Quality Action Day – Particulate Matter

The Indiana Department of Environmental Management (IDEM) has declared that Monday July 17th is an Air Quality Action Day statewide for  Particulate Matter (PM 2.5).

Current air monitor readings across the northern Indiana remain high for particulates and ozone as the Canadian wildfire plume continues to move slowly through the state. Particulates and ozone are expected to be Unhealthy for Sensitive Groups.

As of 10 am, the Air Quality Index had reached Unhealthy for everyone.



Particulate Matter (PM 2.5)

Unhealthy for Sensitive People

Fine particulate matter settles deep into the lungs and cannot be easily exhaled.

Under current conditions, everyone should take steps to reduce their exposure including shortening the amount of time active outdoors or choosing less strenuous activities.

Do your part to help clean the air by taking action!

  1. Carpool or use public transportation
  2. Avoid using gas-powered equipment
  3. Turn off engines instead of idling
  4. Do not burn trash or other debris
  5. Use propane gas instead of charcoal when grilling
