Landfill Gas Risk Assessments & Buffer Zone Audits

Landfills can potentially discharge landfill gas, offensive odours, noise, litter and dust, and closed landfills have the potential to discharge landfill gas for more than 30 years after they last accept waste.
Environmental consultants and EPA–accredited auditors at EESI are well–versed in performing landfill gas risk assessments and audits, and provide expert buffer zone design, management and auditing services.

Uncovering Potential Risks to Keep Communities and the Environment Safe

Landfill gas risk assessments identify potential risks posed by landfill gas (LFG); a combination of methane, carbon dioxide and other gases generated by the decomposition of organic materials within a landfill. If not managed properly, these gases can be hazardous to human health, the environment and surrounding infrastructure. Buffer Zones may include gas collection systems in the areas surrounding a landfill, that are designed to keep landfill gas, as well as other potential hazards such as leachate or runoff, from entering nearby structures. Correct buffer zone placement and management is important to reduce the amount of LFG that is released into the atmosphere or to capture and treat the gas before it enters the environment. Additionally, buffer zones can also be used to reduce the amount of noise and air pollution from the landfill.
