One of the most important processes in today's industrial world, the Nexus Interaction, is known as Water, Soil and Wastewater (WSW). The purpose of this research is to provide a network model that can be used to determine the state of the hazards caused by Irrigation of land with untreated municipal wastewater. Methods of this study include the stages: knowledge of the study area, quantitative and qualitative assessment of surface water of the ministry of the earth, determination of stability indicators and interlinkeges matrices, evaluation of interveners, comparison of interventions and management solutions. According to the measurements, the water quality index for groundwater was 71% It has a relatively bad pollution and 29% is relatively bad. Also, the amount of metals in the house has only four parameters of barium, lead and vanadium in some places higher than the standard, and in vegetables, the amount of lead and cadmium is more than the limit. According to the Nexus radar chart, the highest The pressure from pollution in the first stage is on agricultural products and then on the health and environment of the community
