ABSTRACT: One of the problems of urban life is groundwater pollution. In this study, the water quality of wells in Robat Karim villages of Tehran for drinking and agricultural consumption was investigated. First, the quality of drinking water was assessed using the Schuler diagram. Then, with the help of Wilcox diagram and salinity and SAR parameters, water quality in terms of agriculture was studied. In the next step, water quality in terms of industrial application was evaluated by calculating LSI and RSI. In the study of water quality of wells for agricultural use, it was found that Manjilabad well water in both years and Allard in 2019 is in C2S1 class, which is one of the good waters for agriculture. Also, Vahnabad, Sefidar and Anjumabad wells in 2018 and 2019 and Shahrabad and Allard in 2018 are in C3S1 class. The water of other wells is in C4S2 class every two years and is not suitable for agriculture or it is necessary to cultivate resistant crops. In the study of water quality for drinking water, Manjilabad well was in a very good range in terms of total solutes. The water of Allard region is drinkable in terms of salt in 2019, Shahrabad, Shahrestanak, Vahnabad and is in a good range. The study of LSI index in 2018 and 2019 in the wells of Robat Karim city showed that the index of some wells is higher than zero and some are less than zero. In the study of RSI index, due to the high value of the index, there is an increase in corrosion in the pipes, especially in wells where this index is more than 8. The best quality area with a distance of D> 300 is related to Manjilabad and Wahhanabad and the worst is Hakimabad with D <100.
