Air Quality Trends

Air quality is better now than it has ever been in Chattanooga and Hamilton County. But as the federal standards get tighter, we must work harder to meet them.  Air concentrations for two pollutants, ozone and particulate, are of distinct importance because not meeting them hampers our ability to bring new industry and new roads to our hometown. (To learn more about what Hamilton County is doing to control ozone and particulate, check out our Pollution Solution program.)

The following graphs show pollution levels at local monitors from 2000-2009.  The downward trend is expected to continue.
