EPA Warns: Air Quality Hazardous in Parts of Northern Illinois

Wildfire smoke from Canada is drifting south and will impact air quality in Northern Illinois starting Thursday (6/5).

Illinois EPA Declares Air Pollution Action Day

According to a press release from the Illinois Environmental Protection Agency, there will be elevated levels of particulate pollution on Thursday, Jun 5.

The Illinois EPA has declared an Air Pollution Action Day and includes the counties of Cook, DuPage, Kane, Kendall, Grundy, Lake, McHenry, and Will.

Wildfire Smoke Drives Hazardous Air Conditions

The upper third of the State of Illinois is expected to have air quality reach the Unhealthy to Sensitive Groups range, which is level Orange on the national Air Quality Index (AQI).

This marks the first Action Day of 2025, as air quality for June 4 and 5 is expected to remain in the USG category, especially during high-concentration hours.

Health Risks and Protective Measures Urged

Northern Illinois residents with asthma, chronic lung disease, children, and active outdoor adults are being advised to take precautions when air quality is diminished.

Symptoms like wheezing, coughing, fatigue, or shortness of breath may get worse under the current air conditions, and medical professionals recommend avoiding strenuous outdoor activity, but you should seek medical attention if symptoms worsen.
