Sht SHEET NO DRAWING NO Anatomy of a Landfill Buffer Area Leachate (Arrows) Leachate is a byproduct of landfills, formed by, the decomposition of solid waste mixed with water. Leachate will percolate through the layers of a landfill toward the collection system. Landfill gas extraction Well A series of wells are used to extract gas from decomposing waste. Landfill Gas Disposal The collected gas is disposed either by thermal destruction in flares and/or converted to LNG in a gas utilization facilit Landfill Gas Condensate Disposal The collected gas condensate is collected in storage tanks mixed w/ groundwater and used for onsite dust control. Plastic Liner Polyethlene liner is installed to prevent leachate from draining into groundwater. 9: Creating a Cell Each day trash spread, compacted, and covered with a layer of soil. This pocket of waste is called a cell. Old Cells By compacting, and covering waste in one -day units, the formation of methane gas, and leachate is reduced. IP Buffer Impacted Groundwater/ Area Leachate Disposal P The collected impacted groundwate rlleachate is used for on -site dust control. Soil Layer A 24 -inch layer of soil seperate the first cell and Geotectile Mat Geotextile Mat A non woven fabric mat protects the plasticland fill liner from the gravel in the washed rock layer. Liner Seams Sections of the plastic landfills liners are bonded together by heat welding.Seams are tested while the landfill is in use for strength and Impermeability. • Landfill Slopes The slopes of a landfill are lined with a geotextile non woven fabric mat and a polyethlene liner. The mat and liner are anchored inside the earthen embankment. 2' Soil Layer Washed Rock Leachate percolates through this layer of washed gravel. Compacted Clay Compacted clay provide a secondary barrier to prevent leachate migration to groundwater. Leachate Collection Pipe - Leachate drains into pipes where it is pumped into holding tanks_ Ground Water
