The Boise Cascade Moonlight Rock Industrial Landfill was experiencing unacceptable odors resulting from omission of hydrogen sulfide gases. A total recovery cap and gas collection system was constructed to effectively solve the gas problem and further reduce leachate generation caused by rain infiltration. The landfill was determined to be very unstable due to the saturated state of the contained sludge and debris waste. Biaxial geogrid was used to cover the entire thirty-five acre site and stabilize the waste such that construction of the cap and gas recovery system could be constructed.
