Air Quality Index (AQI)
The U. S. Environmental Protection Agency (EPA) has

Quality Index (AQI) for rating air quality. This scale is based on the
National Ambient Air Quality Standards
(NAAQS). The AQI is not routinely updated
on weekends and during holiday periods. On those days, please call the Air
Quality Index Hotline at (800) 249-1234 or (860) 424-4167 or link to EPA
AIRNow State of Connecticut for the most current air quality
