Current 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 matter, are of distinct importance because not meeting them hampers our ability to bring new industry and new roads to our hometown.  

The following graphs show pollution levels at local monitors over the last 10 years.  The downward trend is expected to continue.
