.Oil contamination of soil and groundwater resources are one of the most dangerous pollutants and their remediation from environment are a necessity. High costs of ex-situ methods of aquifer remediation have increased the use of in-situ methods. Designing a remediation system needs management models and optimizing process by simulation of these models to identify the most efficient and economical method. One of cost-effective in-situ remediation method is use of Permeable Reactive Barrier (PRB). These walls are placed in the path of groundwater flow and pollutant plume in order to clean dissolved phase of pollutants by biological, chemical and physical processes permanently, semi-permanent or as replacement units. Some of the materials that were used successfully in these walls are zero-valence iron, active carbon, zeolite, lime and other alkali materials, apatite etc.The main objective of this study is to use natural zeolite (clinoptilolite) in a permeable reactive barrier (PRB) and evaluation of the efficiency on decreasing BTEX contamination. In this regard, an experimental sand tank model with dimensions of 50cm, 70cm and 140cm was designed and developed to simulate groundwater flow and pollution transport and estimation of diffusion and adsorption capacity of zeolite Ten steps carried out for modeling of process includes problem definition, a research on former studies and data collection, determining the components and parameters, assigning cleanup scenarios, designing a preliminary plan of the model (conceptual model), model making, running and employing the model, sampling and testing, modeling results, interpretation of the results and performance evaluation of model. Fourteen piezometers were located inside the model to monitor and sample the groundwater. Hydraulic properties of the aquifer were calculated and hydraulic gradient was estimated 0.0063. Groundwater flow velocity was calculated for the first and last day of the experiment 0.6 and 0.4 m/ day, respectively. BTEX was used as contaminants which was injected in the upstream amounted to 40 ml
