Chemical quality of drinking water in Bandar Abbas

Introduction: Natural water normally consists of mineral compounds, suspended solids and dissolved gases. Some of these components are necessary for human health, but if more than allowable limits, they will endanger the human health. In this research, important clinical parameters in drinking water of Bandar Abbas were evaluated to compare with the national standards. Methods: In this descriptive study, 33 samples were taken from the reservoirs in the second half of the year 2003 and were analyzed. Titrimetric and instrumental tests were performed on the samples. Titrimetric tests included total hardness, calcium, magnesium, chloride and the alkaline contents of the water; and the instrumental tests included electro conductivity (EC), total dissolved solids (TDS), turbidity, PH, fluoride, iron sodium, nitrate content of the water. Descriptive statistics and Excel software were used for data analysis. Results: The study revealed that the concentration of fluoride, sulphate, chloride, sodium, nitrite, calcium ions, total hardness, EC, TDS in ground water reservoirs were more than maximal allowable limits. All of the tested parameters in Minab surface reservoir met the related standards except for TDS. Conclusion: Chemical quality of drinking water in Bandar Abbas doesn’t cause any health problems, but as groundwater has low quality and being mixed with surface water, some of the parameters don’t meet the desirable.
