The primary purpose of the study is to investigate the origin and distribution of fluoride concentrations in various water sources of Maku-Bazargan-Poldasht in the northwestern region of West Azerbaijan by examining the levels of this element in rocks and plants.. Agriculture, as well as rural and urban water supplies, can be given by the water resources of the target area. In November 1400, 60 water samples were collected from the area's wells, springs, Qanat, and surface waters for this purpose, and fluoride pollution in these sources was assessed using geochemical criteria. The fluoride ion ranges from 0.39 to 9.89 mg/L, with approximately half of the samples having values greater than the World Health Organization norm and so unfit for drinking. Multivariate statistical approaches were used to understand the processes that resulted in these variables and to pinpoint the variables influencing fluoride concentration. When fluoride concentrations for various water sources were evaluated, deep wells had the highest fluoride concentrations, and bivariate graphs demonstrated that the processes of dissolving carbonates and ion exchange raise fluoride and carbonate concentrations in water resources. Using cluster analysis and factor analysis of three groups and three components, it was discovered that the results are compatible with the premise that nitrate is anthropogenic and the fluoride anomaly is natural in the research region.
