Assessment of drinking water quality using physico-chemical parameters around Islamic University, Kushtia, Bangladesh

Abstract

The quality of surface water is a very sensitive issue and it is a great environmental concern worldwide. In recent years, there has been an increase in awareness and concern about water pollution across the globe. In order to ascertain water quality for human consumption, some physico-chemical properties were evaluated of the drinking water of ten villages around Islamic University, Kushtia, Bangladesh. Standard methods were used for determining physical and chemical characteristics of the water samples. As, Fe and Mn contents of the drinking water samples were also analyzed by atomic absorption spectrophotometer. The data showed the variation of the investigated parameter in water samples as follows: pH 7.65 to 8.76, Electrical Conductivity (EC) 280 to 750 µS/cm, hardness 120 to 550 mg/l as CaCO3, Total Dissolved Solids (TDS) 210 to 1380 mg/l, As 0.0 to 0.082 mg/l, Fe 0.039 to 2.03 mg/l and Mn 0.0 to 0.41 mg/l. The concentrations of testing parameters of all the drinking water samples were not keeping up the World Health Organization drinking water quality guideline and the Bangladesh Drinking Water Quality Standards.
