Abstract:
A new and useful method and system for estimating LFG generation and gas permeability in a landfill or other subsurface-gas producing body of material is provided. The gas generation rate in a portion of a landfill or other subsurface-gas producing body of material is estimated by obtaining a time history record of atmospheric pressure that is representative of atmospheric pressure at a surface boundary of the portion of the landfill or the subsurface gas producing body of material, measuring the gas pressure at least at one selected location at the landfill (or subsurface body of material) site over a time period that is included in the time history record, and using the atmospheric pressure and the measured gas pressure over the time period to estimate LFG generation rate and gas permeability of the portion of the landfill or the subsurface gas producing body of material. In a preferred embodiment, gas pressure is measured at a plurality of selected locations within the refuse portion of a landfill, and in the case of an unlined landfill in the supporting soil below the landfill, and the measured pressures are used to estimate LFG generation rate and gas permeability of the landfill.
