摘要

Despite the current shortage of landfill capacity in densely populated areas of the nation, the relatively low cost of landfill disposal and relatively high human health risk of refuse incineration indicate that landfilling will continue to be the predominant method of refuse disposal. To control groundwater contamination at municipal landfills, the EPA has proposed new Subtitle D regulations (Resource Conservation and Recovery Act, 1984). Those regulations are premised upon effective leachate control, achieved through utilization of low permeability liners and covers. However, recent research indicates that clay and/or synthetic liners may not prevent leakage of some trace organic compounds in MSW leachate. Furthermore, low permeability covers prevent rapid biological stabilization of refuse, prolonging the liability of landfill owners and operators in addition to delaying return of land to productive use. The report evaluates the feasibility of alternative landfill technologies including on-site and in-situ biological treatment systems and permeable liner systems. The least expensive and most manageable treatment system would couple in-situ biodegradation with a permeable attenuation layer and secondary aerobic treatment.
