We’re expanding our Landfill Gas Operations & Maintenance (O&M) group to address gas and liquid management issues that have become a higher priority for landfill facilities due to the increase of industrial and wet wastes in the waste stream. We provide services for non-routine landfill gas management, contaminated liquid management and extraction, pumping system maintenance, and other activities that enable your facility to maintain its normal disposal operations while remaining in environmental compliance.
The expanded Landfill Gas O&M group provides services to solid waste companies, public sector landfills, various landfill gas-to-energy (LFGTE) developers, and other private waste companies in several categories:
- Routine technical field services like wellhead monitoring, liquids management assistance, etc.
- Non-routine services like specialized small construction services
- Rigorous data management and detailed analysis and reporting each month to advise you on an ongoing basis.
