In this study, three dimensional and two dimensional laboratory experiments were conducted to investigate the effect of water table rising on DNAPL migration, contaminants mass discharge ($M_d$), and residual NAPL distribution. The accumulation of TCE in unsaturated zone was observed in both two and three dimensional experiments. This implies DNAPL sources could exist in unsaturated zone at contaminated sites. It has been investigated that the TCE concentration is proportional to the areal ratio of residual TCE. This means the residual TCE obviously could affect the TCE concentration in aquifer system. The results of the two-dimensional experiment indicated that the contaminant sources in unsaturated zone could lead the $M_d$ increasing with water table rising and the source zone heterogeneity could also highly affect the $M_d$.
