What it means that the EPA wants to call Detroit’s air ‘clean’ and why residents say it isn’t

The EPA proposes to redesignate Detroit's air quality as meeting national ozone standards, but residents and environmental advocates argue that pollution levels remain dangerously high, particularly in Southwest Detroit, citing health issues like asthma and cancer. A recent study by the American Lung Association graded Detroit's air an 'F' due to ozone and pollution levels.
