Method for projecting landfill gas collection rate of a surface collector

摘要

A method for projecting the landfill gas collection rate of a surface collector, including removing some of the cover material from the landfill to expose a test area of the refuse in the landfill and measuring the venting rate of the landfill gas through the test area under essentially steady state pressure conditions in the landfill. Additional cover material is then removed to enlarge the test area and the measuring step is repeated. The measured venting rates are used for projecting the approximate collection rate for a surface collector.
