摘要：Background: Continuous expansion of potable water pollution sources is one of the main concerns of water suppliers,therefore measures such as water safety plan (WSP),have been taken into account to control these sources of pollution. The aim of this study was to identify probable risks and threatening hazards to drinking water quality in Lighvan village along with assessment of bank filtration of the village.Methods: In the present study all risks and probable hazards were identified and ranked. For each of these cases,practical suggestions for removing or controlling them were given. To assess potable water quality in Lighvan village,sampling was done from different parts of the village and physicochemical parameters were measured. To assess the efficiency of bank filtration system of the village,independent t test was used to compare average values of parameters in river and treated water. Results: One of the probable sources of pollution in this study was domestic wastewater which threatens water quality. The results of this study show that bank filtration efficiency in water supply of the village is acceptable.Conclusion: Although Bank filtration imposes fewer expenses on governments,it provides suitable water for drinking and other uses. However,it should be noted that application of these systems should be done after a thorough study of water pollution level,types of water pollutants,soil properties of the area,soil percolation and system distance from pollutant sources..
