Abstract

In order to determine the effective factors in groundwater quality of Bandar Gaz, the related data of seven well was used for testing water sources by graphical and multivariate statistical methods,. The groundwater sources were seen differently according to Stiff and Drouv diagrams. The drawn composite plots were shown the linear procedure between Na+ and Cl-, due to mixture of saltwater and soft water. Dolomite saturated index (SId) was more than calcite saturated index (SIc), because the dolomite dissolve in direction of groundwater flow. According to CORRELATION MATRIX, other ions (except S042- and N03-) were correlated respect with electrical conductivity. CI- has more combination with Na+ and K+. The cluster diagrams show that there are similarity between CI- -Na+ ions and CI- -K+ in groundwater more than 95%, and 85%. With respect to cluster diagrams, the dominated type of groundwater was Ca-S04-HC03 .According to the analysis method; five factors were effective on chemical combination of groundwater. First factor is related to intrusion of salt water because the Na+, K+ and CI- ions have high FACTOR LOADING. Second factor is human activities (seepage of wastewater, absorbing wells etc), because nitrate had the highest load in third factor. The nitrate concentration in groundwater was influenced by wastewater and irrigation of agriculture fertilizers. Third factor is also related to aquifer hydro geochemical process, because FACTOR LOADING of Ca2+ and Mg2+ was decreased and Na+ was increased. Fourth factor could be related to feeding by surface water (river, runoff) because of HC03- and Na+ increment. Fifth factor is related to dissolution of dolomite that causes to increase of Mg2+ FACTOR LOADING.
