The air quality keeps getting better in Richmond.

The Virginia Department of Environmental Quality has issued a code green advisory for the capital region today. Code green means the air poses little or no health risk.

This represents the second day in a row of improved air quality for Richmond.

There was a code orange advisory in effect Tuesday, meaning the air was unhealthy for sensitive groups, but it improved to a code yellow yesterday, meaning the air could mildly affect people who are unusually sensitive to air pollution.
