13 Counties Receive an "F" in Air Pollution Report
Air Pollution remains a serious problem.
The American Lung Association’s State of the Air 2014 report shows nearly half of all Americans live in counties where ozone or particle pollution levels make the air unhealthy to breathe.
13 Indiana counties received an F-grade, including Greene, Vanderburgh and Warrick.
The report says the nation continues to reduce particle pollution, but poor air quality remains a significant public health concern.
