Gas Monitoring System – Gas sampling wells around the landfill that are monitored for methane to detect and prevent methane from moving below ground, through the soil, outside of the landfill. For landfills that have a gas collection system, the pipes throughout the landfill used to collect the landfill gas are also monitored to ensure the landfill gas collection system is operating properly and methane is not escaping the landfill.
