Abstract:
Groundwater in some of the agricultural wells of Hamadan Province (including around the Hamehkasi village) has bubbles of gas and physically its taste is sour, bitter and burning. To postulate its origin and the trend of variation of the composition is important task for planing and continous using. Therefore, in this research, the origin of anomalies and the trending of its composition change was evaluated. For this purpose, six gaseous wells were identified and their electrical conductivity was monitored15 times over three years (five times each year). The trending of their electrical conductivity changes were evaluated by SPSS software. Additionally, from each well, one sample was collected and for determination of the total alkalinity, Electrical Conductivity, Cations and Anions were analyzed. Thier chemical indices were calculated and evaluated by using different diagrams. The results showed that the water of all wells is fresh, show the Ca-Mg-HCO3 type. In these waters, the concentration of soluble carbon dioxide is more than 1000 mg/L. The abnormal composition of wells water due to from reaction between the water and the reservoir rock with involvement of hydrothermal fluids. Part of the reservoir rock consists of lime and the other part consists of marl and evaporite sediments. The statistical analysis of trending of water composition change indicates that the electrical conductivity decreases significantly over time, which firstly, confirms the involvement of hydrothermal fluids in rock-water reaction and secondly, it will be the hope of improving the water quality in future.
