The purpose of this study is to analyze numerically the regional groundwater pollution by TCE (Trichloroethylene) and PCE(Tetrachloroethylene) in J city, Japan. Firstly, we examine the field data measured since 1986 and display the distribution of groundwater level and concentration of TCE and PCE by a computer. Based on these data, we can guess the interrelation between the water balance of groundwater and the diffusion of pollutant in this region.
Secondly, we conduct the sensitivity analysis and the inverse estimation considering the water balance and the hydraulic conductivity distribution.
Finally, we analyze the groundwater pollution and predict the amount of mass transfer into the river from groundwater in this region, using the LOD-CFEM (Locally One Dimensional-Collocation Finite Element Method).
