HEEP COPYRIGHT: BIOL ABS. Columns of domestic waste contaminated with halogenated organic compounds to the extent of 500-5000 ppm wt/wt were eluted with water to assess the extent to which these compounds may be leached from wastes in landfill sites. The concentrations of the solvents perchloroethylene, trichloroethylene and 1,1,2-trichlorotrifluoroethane in leachates were at least 2 orders of magnitude lower than in the solid waste being leached. It would seem, therefore, that evaporation and adsorption will serve to reduce the leachate concentrations of these compounds, which arise in domestic waste landfill as dry cleaning residues, to the part per million level or below. The low solubility of compounds such as dichlorobenzene, dichloronitrobenzene and chlorohydroxyquinoline appears to prevent their appearance in the column leachates at concentrations above a few parts per million. More soluble compounds such as dichlorophenol dichloroaniline, dibromoethane and dichloropropane were detected in leachates at concentrations of tens of parts per million. Adsorption processes appeared to have some capacity for reducing the concentrations of halogenated aromatic compounds in contaminated leachates.
