Organic and inorganic priority pollutants codisposed with municipal solid waste (MSW) in ten pilot-scale simulated landfill columns, operated under single pass leaching or leachate recycle, were capable of being attenuated by microbially-mediated landfill stabilization processes. The results of the investigation have indicated that columns operated with leachate recycle stabilized more rapidly and completely than columns operated under single pass leaching. The behavior and attenuation of admixed priority pollutant loadings were reflected by changes in leachate characteristics and in the total gas production, the gas production rate, and the methane content of the gas produced by the simulated landfill columns. Leachate constituents were retained in the recycle columns, but were principally removed from the single pass columns due to washout. An explicit inhibition threshold for stabilization consequenced by the priority pollutant loadings was not observed for the recycle columns, although retardation was evident for the test column most heavily loaded with heavy metals. In contrast, stabilization in all single pass columns containing organic and inorganic priority pollutant loadings was inhibited. The organic priority pollutants appeared to have less impact on landfill stabilization than the heavy metals.
