Improving the reliability of lfg-generation assessment tests

Brief (i.e. <4 weeks duration) pumping-trials have been used to indicate the economic and scientific suitabilities of landfills for landfill-gas (lfg) harnessing. Some of the challenges and proposed solutions are discussed. The methodology employed, results measured and conclusions drawn, based upon brief pumping-trials conducted at 12 different UK landfill sites, are presented.
