KMOX is reporting that the Fred Weber Sanitary Landfill has a history of landfill gas issues, in that concentrations of methane periodically exceed regulatory limits. In this instance, the owners of the landfill informed property owners and tenants within 1000 feet of the monitoring wells of the problem.

Methane is odorless and colorless, and is the byproduct of the decomposition of waste. In high concentrations it is very flammable. Methane is a common landfill gas, along with carbon dioxide and hydrogen sulfide.
