The codisposal of selected organic priority pollutants with municipal refuse was investigated with four pilot-scale simulated landfill cells operated under the influence of single pass leaching or leachate recycle. The acid-formation and methane-fermentation phases of landfill stabilization were established and described in terms of routine analyses performed on leachate and gas samples for a variety of indicator parameters. During a 15-month period, little evidence of release of butanone, trichloroethane, phenol, pentachlorophenol, 4,6-dinitrocresol, di-n-butyl phthalate, 2,6-dinitrotoluene, 2,4-dinitrotoluene, phenanthrene, hexachloroethane, 2,4'dichlorobiphenyl, and hexachlorobiphenyl was obtained even after elution of as much as 20-bed volumes in the recycle cells. Moreover, patterns of microbially mediated conversion of substrate were not influenced by the presence of the organic priority pollutants and could be accelerated through leachate recycle. Assimilation of the organic priority pollutants throughout th e phase of landfill stabilization was ascribed to physical-chemical and biochemical attenuation and possible fractionation within the waste mass. Additional studies are indicated to further establish assimilative capacities for organic priority pollutants codisposed with municipal refuse in landfill-disposal sites.
