Landfill Gas Monitors

LFG is generated by the decomposition of organic municipal solid wastes such as garbage, garden wastes, and paper products. This process may continue for 20 to 50 years after initial dumping of the MSW. At near steady-state conditions, LFG is typically composed of approximately 55% CH4, 40% CO2, 5% N2, and smaller amounts of NMOCs such as benzene, vinyl chloride and chloroform.

Because of concerns for the health risks and safety associated with landfill gas, regulations under the Clean Air Act have targeted large municipal landfills with performance based regulations for controlling LFG emissions.

Geotech offers a choice of methods for measuring and analyzing LFG. Continuous ground gas monitoring in boreholes for complete assessments of below ground site conditions. Accurate portable instruments for monitoring LFG at key areas of a landfill site. The information they provide is vital for the collection and control of landfill gas.
