Liquids and Landfill Stability – 2021 Solid Waste Webinar Series
July 20, 2021 @ 1:00 pm - 2:00 pm EDTFree
Presented by Michael Yacyshyn, Eric Chiado, and Tim Mitchell
Accumulation of liquids in a landfill can effect landfill stability. Management of liquids in a landfill is traditionally limited to the operation and maintenance of the leachate collection and removal system (LCRS) to remove free liquids that drain vertically through the waste mass. However, some liquids can accumulate in the waste mass and be impeded to flowing to the LCRS due to: excessive stormwater infiltration, varying waste permeability, inconsistent flow patterns, groundwater intrusion into unlined upgradient cells in canyon fills, or varying waste compositions (i.e. wet waste). Methods to analyze and mitigate the impacts of high landfill liquid levels will be presented.
