Abstract: | The effect of mixing three Kentucky, U.S.A. coal slurries with soil on the transport of benzene and trichloroethylene (TCE) through a compacted landfill soil liner was investigated. Using typical values for variables, assuming no competition between contaminants, and a two to one soil-coal slurry ratio all three coal slurries were predicted to maintain the concentration of benzene emanating from a landfill liner below the maximum concentration limit (MCL) of 0.005 mg/l for at least 40 years. The concentration of TCE emanating from a landfill liner was predicted to remain below 0.001 mg/l for at least 100 years. The saturated hydraulic conductivity of a compacted silty loam soil (typical landfill soil liner material) was not found to be affected by the addition of coal slurry at a ratio of two parts soil to one part coal slurry. The results presented indicate that coal slurry amended soil will slow the movement of non-ionic organic contaminants through a landfill liner while the liner retains a low hydraulic conductivity. |
