An examination of temporal/spatial variations in landfill-generated methane gas

The experimental findings of a data-intensive in situ landfill monitoring study are described. Particular attention is given to the methodology employed in collecting the data, analyses of the spatial/ temporal variability of the gas percentages, by volume and the extent to which the variability in collected results is explained by variations in exogenous independent variables. Measurable gas flow rates from the soil could not be detected through the probe system employed in the field study.
