Abstract :

Background and Objective: The study has been done with the aim of chemical Analyze of water sources in area with the help of Aq.QA software and compared with national standard. Method: Chemical quality of ground water sources of area were under study during two stages of sampling the drinking water from 37 station of sampling water in the year of 2010-2011and tested 19 chemical parameters of drinking water. The results were compared with standard values of drinking water and chemical diagrams of water were drawn withAq.QA software. Water types by using stiff diagram and balance or imbalance of anion-cation by ion balance diagram to separate the sources and chemical specification of water by piper diagram were compared for all of the water sources. Findings: Results of the research showed that water type is calcium bicarbonate, in 97% of times. Concentration of florid is less than the authorized limit in 100% of times and concentration of nitrate in both low - water and full water seasons are more than the maximum limit in 3% of sources. Discussion and Conclusion: The type of water was present in all sources of calcium bicarbonate, except for the village of Bauleh, which was sodium bicarbonate, so calcium and bicarbonate ions, cation and anion are predominant. Ion Balance diagram was balanced in 11 water supply sources and had anion and cation balance. Fluoride concentration in 100% of cases was less than the minimum allowed and nitrate concentration in 3% of sources in both low and high water seasons was higher than the maximum allowed.
