The American Lung Association’s 2017 “State of the Air” report shows that not only Georgia, but Rome and Summerville have improved the quality of air in the area.

The group cited the Clean Air Act for cleaning up air pollution.

The report stated that Metro Atlanta had the fewest ozone days reported since the report began 18 years ago. They also made the list for the first time for cleanest cities for short-term particle pollution. 

This year’s report covers data collected by states, cities, counties, tribes and federal agencies in 2013-2015. 

No Georgia cities made the list of the most polluted in terms of ozone and particle pollution.

Four Georgia cities were among the cleanest for ozone: Brunswick, Rome/Summerville, Savannah/Hinesville/ Statesboro, and Bainbridge.

Several made the list of cleanest for short-term particle pollution: Atlanta/Athens/Sandy Springs, Augusta/Richmond County; Brunswick; Columbus; Rome/Summerville; Savannah/Hinesville/ Statesboro; and Valdosta.

Much of the air quality improvement came from cleaning up major pollution sources, such as coal-fired power plants, and retiring old, dirty diesel engines, the Lung Association said.

The report also broke down measurements of high ozone days. Metro Atlanta counties Fulton, Henry and Rockdale each earned an “F’’ grade, while Gwinnett and DeKalb Counties each got a “D.” Glynn and Chatham joined Chattooga, Clarke, Columbia, Muscogee, Paulding, Richmond and Sumter Counties with getting an “A” on ozone.

Getting an “A’’ on particle pollution were Chatham; Clarke; Clayton; Cobb; DeKalb; Floyd; Fulton; Glynn; Gwinnett; Hall; Houston; Lowndes; Muscogee; Paulding; Richmond; Walker; and Washington.
