An air quality alert has been issued in parts of Maine due to smoke from the still-burning fire at a trash facility in Orrington.

The full extent of the fire’s environmental impact is unclear at this time, but there's concern about potential threat of dioxins.

An air quality alert has been issued as a fire continues to burn at an Orrington trash facility. The Maine Department of Environmental Protection issued the alert, as smoke from the fire settles in Midcoast and Downeast Maine, leading to poor air quality.

The Maine DEP said particle pollution in the smoke could reach unhealthy levels for sensitive groups, such as children and people with respiratory problems.
