Maine Unknown Air Quality Alert | Effective 06/30/2026 12:26

The Maine Department of Environmental Protection's Bureau of Air Quality has issued an Air Quality Alert for ozone from 10 AM to 11 PM EDT Wednesday. Ozone levels are expected to rise into the Unhealthy for Sensitive Groups range on Wednesday. The rest of the state except the Northern and Western Mountain regions are expected to reach the Moderate range. The Maine Department of Environmental Protection recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, older adults, those who work outdoors, those with pre-existing respiratory problems such as asthma, and those with heart disease. It is okay to be active outdoors. But if you experience symptoms such as shortness of breath, coughing, throat irritation or an uncomfortable sensation in your chest, please consider limiting the intensity and duration of your outdoor activities. A toll free air quality hotline has been established so Maine residents can stay informed on the air quality situations. The toll free number is: 1-800-223-1196. Additionally the Maine Department of Environmental Protection has the air quality forecast available on the web at www.maine.gov/dep/air/aqforecast.
