To protect the air quality and residents of Central Indiana, the Office of Sustainability is issuing a Knozone Action Day for the remainder of today, July 21, 2021, as well as tomorrow, July 22, 2021. During Knozone Action Days, the air quality may become unhealthy for sensitive individuals, especially active children, the elderly, and anyone suffering from lung disease, asthma, COVID-19, or other serious health problems.
Indiana air quality has been impacted by wildfire smoke moving southwest across the state. Local air quality experts examine levels of fine particulate matter, or PM2.5, to determine safety. This matter includes microscopic dust, smoke particles, and soot.
The air quality forecast indicates that elevated levels of fine particles will intensify this afternoon and evening over southern Indiana and then recirculate back across the state tomorrow. Local partners are monitoring the data and will call public health advisories as needed.
