Fig. 2. Measured and simulated breakthrough curves of dimethylphthalate (DMP) column experiments with Oakville A soil. The simulated breakthrough curves were estimated using the parameter set given in Table 1. The local equilibrium assumption (LEA) breakthrough curves were calculated with the 14-d distribution coefficient given by Maraqa et al. (1998). The letters in each figure denote first moments E[T] calculated from the measured curve (a), fitting CXTFIT to measured data (b), the 14-d distribution coefficient (c) (all given by Maraqa et al., 1998), and the parameters of the linear two-stage model estimated from the batch data (d) (this work)
