A fire has been smoldering underground at the Bridgeton landfill for more than two years. People living in the area have complained of strong chemical smells, and of symptoms including burning eyes and headaches.

Earlier this month, the Missouri Department of Natural Resources tested the air there for toxic chemicals. The DNR took samples on two separate days at six sites near the landfill, including some in a residential area.
