The use of engineered lightweight fill for landfill cover remediation
In 1991, SCS was retained to provide design and construction engineering services to retrofit a landfill gas migration control system and regrade/repair an existing low-permeability soil final cover system for a 10-acre closed landfill located in west-central Florida. The final cover system modifications consisted of regrading the top of the landfill to re-establish positive drainage across and off of the top of the landfill. While active, the landfill had received municipal solid waste (MSW), commercial solid waste, and various industrial wastes and sludges. The landfill was closed in the early 1980`s. At the time of filling, the subject landfill was operated as a trench fill. A series of 40-foot deep trenches were excavated across the fill area, and the MSW was placed and compacted into the trenches. The soil excavated during construction of the trenches was used to construct berms along the sides of the individual trenches. No constructed bottom liner or leachate collection system was incorporated into the design. This report presents the results of a conceptual evaluation of utilizing expanded polystyrene blocks or Geofoam, as the lightweight fill component for an alternative cover remediation.
