Abstract :In this study, it was aimed to evaluate the hydrogeochemical properties and water quality for drinking, agricultural irrigation and other purposes of ground water resources within the boundaries of Yozgat Province. Within the scope of the study, the analysis results of water samples taken from 79 wells in 12 districts within the provincial borders between 2016 and 2019 were examined. Hydrogeochemical evaluation of water samples was performed according to Piper diagram, Spearman correlation, Gibbs diagram, Cluster analysis and Factor analysis. Water quality was evaluated according to standards and regulations regarding drinking water, utility and agricultural irrigation. According to the results of Spearman correlation analysis, the highest relationships were observed between electrical conductivity (EC), sulfate (SO4) and total dissolved solids (TDS). There are two different types of groundwater in the region: water with Ca-Mg-Cl and water with Ca-Mg-HCO3, and it has been concluded that the rock dominant mechanism is effective on the quality of water resources. Cluster analysis showed that regions close to each other have similar water characteristics due to similar geological structure. In factor analysis, Factor 1 constitutes 41% of the total variance. Additionally, it has been determined that the water resources in the region are suitable for use and agricultural irrigation.
