BRIDGETON, Mo. – The fifth round of air quality testing will begin Monday at the Bridgeton Landfill.

The landfill has been smoldering for years, and this week 40 air monitors will gather information about what's going on in the air around the landfill. The information will be made public after it's gathered, and the results will be measured against information taken in previous surveys.

According to the Bridgeton Landfill team, each of the previous surveys have shown no threat to public health.

Underground smoldering is occurring at the Bridgeton Landfill, which sits next to the West Lake Landfill, where Cold War-era nuclear waste is buried.
