Abstract
Pumping test and closed flux chamber technique were used to evaluate the performance of horizontal landfill gas collection system at the Rachathewa sanitary landfill, Samutprakan, Thailand. Two investigated areas consisting of three horizontal extraction wells each with a total length of 150 meters with a well spacing of 15 m were used. The closed flux chambers were used to measure the surface landfill methane emissions before and during pumping tests. Pumping tests were done for a period of two weeks. The gas adjustment was tuned to maintain landfill gas (LFG) quality of greater than 50 % C[H.sub.4] and less than 2 % [O.sub.2]. Portable landfill gas analyzer and ...
