If you’re looking for a county with clean air, the American Lung Association says there’s one county in North Alabama that stands out.

DeKalb County received A grades in the association’s annual State of the Air report, which measures ozone and particle pollution.

Using data from the Environmental Protection Agency’s Air Quality System, DeKalb ranked low in both pollution types monitored. 

Colbert County received a B grade in ozone and an A in particle pollution.

Madison and Morgan counties both received C grades in ozone and As in particle pollution.

No other counties in North Alabama collect data that could be used in the study, so they were not graded.
