‘The Air We Breathe:’ How industry is polluting Cicero’s air

"The Air We Breathe" is a yearlong investigative project by two nonprofit newsrooms, the Cicero Independiente and MuckRock, who have been monitoring air pollution in Cicero. What we found: Cicero’s air quality is much worse than surrounding Cook County neighborhoods, and it’s worse than what the Environmental Protection Agency and pilot programs run by the city and Microsoft have routinely reported.

Poor air quality and pollution has been a persistent problem in Cicero and nearby Little Village for decades, with experts attributing it to Cicero’s century-long history of heavy industry, its residential density and a lack of parks and trees.

In March 2023, the Independiente partnered up with MuckRock to install air quality sensors on volunteers’ homes. These sensors are installed in three locations in Cicero: near 51st Court and 14th Street, 54th Court and 31st Street and 59th Avenue and 38th Street. Our sensor readings showed that Cicero’s air quality is markedly worse than places with other bustling industrial corridors in Chicagoland, such as the Lower West Side and Navy Pier.

The health effects of living in a place with decidedly poor air quality can be devastating and stretch across generations. Emissions from gas- and diesel-powered trains, trucks and machines include harmful pollutants: volatile organic materials, or VOM, which include cancer-causing compounds.
