The Paper present unconfined groundwater flow and solute transport modeling under landfill (case studies – landfill Valea Manastirii) using the PMWIN applications. Modeling purpose is to constitute extending pollution zone of aquifers in space and time generated of polluted infiltration in landfill Valea Manastirii, Gorj country. Knowledge of extending of pollution zone is necessary to settle technical measures to closing nonconformity landfill. The companion software Processing Modflow for Windows (PMWIN) offer a totally integratedsimulation system for modeling groundwater flow and transport processes with MODFLOW-88, MODFLOW-96, PMPATH, MT3D, MT3DMS, MOC3D, PEST and UCODE.
