Abstract

• This study deals with the determination of physicochemical properties, trace elements and bacteriological analysis of tube-well water. The tube-well water samples were collected from two sites of Kyauktan Village, Minbu Township. Water samples were analysed from the study area, seasonally in 2018. The physicochemical properties such as the temperature, pH, the electrical conductivity (EC), the turbidity, total dissolved solids, total alkalinity, chloride concentration and salinity of all water samples were measured. The pH values of the collected samples were higher in summer than the other two seasons. The total dissolved solids values were high in rainy season. The total hardness values, dissolved oxygen (DO), biochemical oxygen demand (BOD) and chemical oxygen demand (COD), of water samples were also determined. Some trace elements such as, lead and cadmium were analyzed by Atomic Absorption Spectrophotometer (AAS). Arsenic was detected by Arsenator. The bacteriological analysis of total coliform and Escherichia coli was done in the collected water samples. The total coliform and Escherichia coli counts were higher in rainy season than other seasons. The experimental results obtained were compared with the WHO standards for human health. The aim of this research is to study water quality for human consumptions and to prevent environmental pollution in this study area.
