Abstract :

Background and Objective: Providing safe drinking water is so essential for human consumption adequately and healthy. Therefore, knowledge of the physicochemical quality of water resources can play a major role in their utilization and consumption for drinking. Measurement and monitoring of water quality parameters is the first step for ensuring safe water. The aim of this study was to investigate the quality of drinking water wells of Zarghan plain in Fars province.Methods: For this purpose, the data of meteorology, groundwater level and physicochemical experiments of 12 parameters including Total Dissolved Solids, Total Hardness, Electrical Conductivity, pH, Sulfate, Bicarbonate, Nitrate, Sodium, Calcium, Magnesium, Chloride and Fluoride of ten drinking water wells in Zarghan rural district during 2011-2016 were used.Findings: Data were analyzed by Pearson correlation matrix and one sample t-test using SPSS software. The results of comparing different parameters of water wells in Zarghan area with the national standard during 5-year-period showed that with decreasing groundwater level due to drought, the amount of Magnesium, Chloride, Sodium, Total Hardness and Electrical Conductivity increased and exceeded the maximum standard limit for drinking.Discussion and Conclusion: Water wells no. 1, 2, 4 and 7 have a better level of drinking water quality than water wells no. 5, 6, 9 and 10 due to decreasing rain and drought, uncontrolled harvesting of groundwater resources, and differences in the matter nature and type of soil of each part of the area.
