Specialist Services in Landfill Gas Monitoring

Landfill gas monitoring may be undertaken to fulfil regulatory requirements and should also be considered essential for risk management. When conducted by experienced specialists monitoring programs can also be effective tools to assess performance and guide improvement in the effectiveness of gas management systems.

Our services cover all landfill compliance, best practice and risk management needs:

  • Landfill site assessment and monitoring
  • Landfill gas risk assessment and management plans
  • Surface monitoring can be an effective diagnostic tool to gather a special understanding of the integrity of caps and performance of the extraction system. Our surface monitoring services are undertaken consistent with regulatory requirements.
  • Subsurface perimeter monitoring is essential for gas control management and we have the required expertise to develop effective monitoring strategies to ensure migration risks are suitably managed.
  • Ambient air monitoring and community managementcan be employed where a landfills is the cause of ongoing odour compliant to both verify sources and quantify impacts. This is delivered our unique mix of air modelling engineers, meteorologists, toxicologist and LFG management specialists.
  • Extraction system monitoring servicesinclude data collection and analysis from individual well heads to overall system performance.  Providing third party oversight can ensure not only are environmental risks (like migration or landfill fire) are being suitably controlled but can also offer improved revenue returns from energy, carbon or royalty opportunities.

Act early and save money

Delaying action until community or regulatory pressure requires it can be costly. Numerous examples exist of the high cost of landfills failing to understand the complexity of landfill gas management.

The examples below highlight why it is essential to engage experienced Landfill gas practitioners, professionals who understand the functional limitations and possibilities of control systems:

Migration:  In 2008 the fire service directed the evacuation of a housing estate in the south eastern suburbs of Melbourne as a result of methane migration from a small regional landfill.  That case eventually went to court with the final costs of remediation and litigation most likely in excess of $50 million. This event occurred despite the fact the landfill operated under a EPA licence, with landfill gas control systems in operation and monitoring programs in place.

Odour:  Managing community and regulatory perceptions can be an important reason to take proactive steps.  With air space running out one of Australia’s largest landfills had failed twice in seeking approval to expand  due to community resistance, particularly over odour concerns.  This decision directly impacted $100’s of millions in investment and permanently damaged community perceptions.

With over three decades of landfill gas management experience across more than 100 landfills, our landfill gas consultants have unparalleled industry experience and specialise in understanding and managing landfill gas risk.
