Abstract

Groundwater is the most important for agriculture, drinking and industry. On the other hand, the quality of groundwater is the other essential aspect for human. The quality of groundwater overall depend on a few factors such as geological information and human activities. In this study, the quality of the groundwater of Asadaabad aquifer was surveid by using statistical and hydro geochemical methods. Asadabad aquifer is located in the west of Iran, which is about 926 kilometers square. Thirty water samples were prepared in June of 2017. The samples were transferred to the hydrogeochemical Shahrood University lab.The factor analysis methods and hydrochemical methods were used to find the main component which influences groundwater. Additionally, the proposed method was used to cluster the groundwater of the Asadabd aquifer.The hydrochemical methods showed that dolomite information is the main factor that affects groundwater quality. Additionally, there are results of factor analysis in which the main component (weathering of carbonate rock) is the biggest quota from others. Using the results of factor analysis, hydrochemical surveying and the proposed method, groundwater was clustered in four areas, which are unique in water chemistry. The carbonate formation is the dominant set in the area. Using the statistical method and hydrochemical survey, the most important component, which affects groundwater, is the weathering of carbonate rock.
Four areas are the output of the proposed method which used the result of the factor analyses and hydrochemical methods.
