ABSTRACT:
A method of withdrawing landfill gas from a landfill without drawing air into the landfill comprising providing a well in the landfill and withdrawing landfill gas from the well at a plurality of different withdrawal rates. The pressure at a selected region within the landfill is detected while the landfill gas is being withdrawn. A relationship is then established between the withdrawal rate and the pressure at the selected regions. This relationship is utilized to establish a maximum withdrawal rate, and this maximum rate occurs at approximately zero gauge pressure. Landfill gas is then withdrawn from the well at no more than about the maximum withdrawal rate.
