AB  - One-dimensional (1D) advection-dispersion transport modeling was conducted as a 
      conceptual approach for the estimation of the transport parameters of fourteen 
      different phenolic compounds (phenol, 2-CP, 2-MP, 3-MP, 4-MP, 2-NP, 4-NP, 
      2,4-DNP, 2,4-DCP, 2,6-DCP, 2,4,5-TCP, 2,4,6-TCP, 2,3,4,6-TeCP, PCP) and three 
      different inorganic contaminants (Cu, Zn, Fe) migrating downward through the 
      several liner systems. Four identical pilot-scale landfill reactors (0.25 m3) 
      with different composite liners (R1: 0.10+0.10 m of compacted clay liner (CCL), 
      L(e) = 0.20 m, k(e) = 1 x 10(-8) m/s, R2: 0.002-m-thick damaged high-density 
      polyethylene (HDPE) geomembrane overlying 0.10+0.10 m of CCL, L(e) = 0.20 m, k(e) 
      = 1 x 10(-8) m/s, R3: 0.002-m-thick damaged HDPE geomembrane overlying a 
      0.02-m-thick bentonite layer encapsulated between 0.10+0.10 m CCL, L(e) = 0.22 m, 
      k(e) = 1 x 10(-8) m/s, R4: 0.002-m-thick damaged HDPE geomembrane overlying a 
      0.02-m-thick zeolite layer encapsulated between 0.10+0.10 m CCL, L(e) = 0.22 m, 
      k(e) = 4.24 x 10(-7) m/s) were simultaneously run for a period of about 540 days 
      to investigate the nature of diffusive and advective transport of the selected 
      organic and inorganic contaminants. The results of 1D transport model showed that 
      the highest molecular diffusion coefficients, ranging from 4.77x10(-10) to 10.67 
      x 10(-10)m2/s, were estimated for phenol (R4), 2-MP (R1), 2,4-DNP (R2), 2,4-DCP 
      (R1), 2,6-DCP (R2), 2,4,5-TCP (R2) and 2,3,4,6-TeCP (R1). For all reactors, 
      dispersion coefficients of Cu, ranging from 3.47 x 10(-6) m(2)/s to 5.37 x 10(-2) 
      m2/s, was determined to be higher than others obtained for Zn and Fe. Average 
      molecular diffusion coefficients of phenolic compounds were estimated to be about 
      5.64 x 10(-10) m2/s, 5.37 x 10(-10) m2/s, 2.69 x 10(-10) m2/s and 3.29 x 10(-10) 
      m2/s for R1, R2, R3 and R4 systems, respectively. The findings of this study 
      clearly indicated that about 35-50% of transport of phenolic compounds to the 
      groundwater is believed to be prevented with the use of zeolite and bentonite 
      materials in landfill liner systems.
