Abstract :
Background and Objective: the aim of this paper is the assessment of groundwater with respect to the chemistry and its subsequent impact on groundwater quality for drinking and irrigation consumption in the Qheydar area, Zanjan Province.Material and Methodology: In order to determine of physico-chemical parameters, anions, cations and heavy metals were sampled from the water sources of the study area and measured by different methods.Findings: The groundwater facies in the studied area belong to the bicarbonate to chloride type and generally hard due to the total hardness, Except for 2 Samples the others have hardness. In terms of EC and sodium adsorption ratio (SAR), Na% and residual sodium carbonate (RSC), the groundwater is Very salty in more of samples and totally unsuitable for agriculture. Moreover, dissolved heavy elements and Ions kind of As, Se, NO3 and SO4concentrations in the groundwater of the Qheydar area have the unsafe limits which recommended by the WHO.Discussion and Conclusion: Based on ionic ratios, Gibbs diagram, saturation index and multivariate analysis for indicating the sources of inorganic solutes in groundwater indicate carbonate sources and ion exchange have the greatest impact on water chemistry in the area. The metal index (MI) showed that some samples were non-drinking. Also, the results obtained from factor analysis showed the effect of salinity, agriculture, geology and faults in the Qeydar study area.
