Environmental investigation, landfill gas mitigation, and long-term monitoring services to protect public health and nearby residential housing in Michigan.
The City of Mount Clemens owns a municipal landfill that posed potential safety concerns due to the migration of methane and other landfill gases toward nearby residential neighborhoods. Elevated methane concentrations and subsurface pressure conditions required detailed investigation, coordination with multiple regulatory agencies, and implementation of long-term mitigation measures to protect public health and safety.
AKT Peerless has supported the City of Mount Clemens at this site since March 2012, providing ongoing environmental investigation, landfill gas evaluation, and mitigation system design and operation. The project has evolved over time in response to site conditions, monitoring data, and regulatory requirements, requiring a phased and adaptive approach to landfill gas control.
AKT Peerless conducted comprehensive investigations to define the perimeter and depth of the landfill, characterize waste materials, evaluate methane and landfill gas concentrations, and assess subsurface pressure conditions. Services included subsurface investigations of soil, groundwater, and soil gas using environmental drilling, Geoprobe methods, and ground-penetrating radar (GPR). AKT Peerless also performed PFAS sampling as part of ongoing environmental characterization.
AKT Peerless coordinated closely with the U.S. Environmental Protection Agency Agency for Toxic Substances and Disease Registry (ATSDR), Michigan State Housing Development Authority (MSHDA), Michigan Department of Environment, Great Lakes, and Energy (EGLE), Macomb County Health Department, and the City of Mount Clemens to develop and implement protective actions. These actions included design and installation of active methane extraction systems, expansion of mitigation systems based on monitoring data, installation of methane detectors and alarms in residential units, continuous methane and pressure monitoring, regulatory reporting, and ongoing operations and maintenance (O&M) of the mitigation systems.
AKT Peerless successfully implemented and continues to operate landfill gas mitigation systems that control methane migration and protect nearby residents. Two active methane extraction systems were installed and expanded as needed based on long-term monitoring results, with initial flaring used to safely manage elevated methane concentrations.
Through continuous monitoring, adaptive system management, and coordination with regulatory agencies, methane levels and subsurface pressures are actively controlled, reducing risk to surrounding neighborhoods. Ongoing operations, maintenance, monitoring, and reporting ensure continued compliance and long-term protection of public health and safety at this municipal landfill site.
