History of Chattanooga's Air Quality

Hamilton County's air is cleaner than ever, but every day we work towards meeting the federal requirements. Without the help of our citizens, it would be impossible to keep our air clean. We encourage everyone to reduce air pollution by reducing vehicle trips through carpooling, walking or riding a bike, or taking mass transit. Other steps citizens can take include fueling their vehicles after 6 p.m., not mowing their lawns on high pollution days, and choosing alternatives to burning brush (wood chipping, brush pick-up services).

Without the cooperation among government, industry, and a concerned citizenry, the progress Chattanooga has made would not have been possible. Please help us make air pollution history in Chattanooga and Hamilton County now and for generations to come.
