Introduction. Fugitive landfill gas entered adjacent homes and buildings and accumulated to explosive levels. The objective was to effectively eliminate the threat of explosion and to recover the methane for fuel.
Site Assessment. Analyzed historical data, evaluated landfill gas transport mechanisms---diffusion, effusion, and convection---as applied to the landfill, and examined the landfill gas monitoring and extraction wells data record to devise a gas recovery solution.
Landfill Gas Barriers. Evangelista countered a contractor's methane recovery design with an innovative alternative design that proposed subterranean gas migration barrier options, including deep soil mixing, with neighboring gas monitoring and extraction wells for fuel recovery.
