ATLANTA -- Air Quality Awareness Week recently came to a close, and 15 metro Atlanta counties didn't quite make the clean air cut.
The U.S. Environmental Protection Agency recently changed its standards of attainment for ozone standards from .08 parts per billion to .075 parts.
The change means that 15 formerly compliant counties were re-designated at nonattainment for ground-level ozone: Bartow, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Newton, Paulding and Rockdale.
To clean up the air, residents can try carpooling to work or taking MARTA if possible; fewer cars on the roads means more breathable air for everyone in metro Atlanta.
