The highest AQ index in Connecticut (as of 9:00 EDT) is currently the New London-Groton area. Particle Pollution (PM2.5) is measuring at 52 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Greenwich area. It is forecasted to be Unhealthy for Sensitive Groups, meaning members of sensitive groups may experience health effects. The general public is less likely to be affected.
