Over the years, the decrease in drinking water quality has become a matter of concern for living organisms. This paper shows the physical and chemical characteristics of five different drinking water supplies for the residents of the Teligati region, Khulna. Both treated water supply and natural water supplies were taken into consideration for the research. This research aims to properly understand the Drinking Water Quality Index (WQI) that is being compromised for various geographical and artificially created problems. Using proper experiments conducted in the Environmental Lab of KUET, this study was conducted to determine the specific values of Bio-Chemical Oxygen Demand (BOD), Dissolved Oxygen (DO), pH, Total Hardness (TH), Electrical Conductivity (EC), Chloride concentration, Turbidity, Color, Total Suspended Solids (TSS) and Total Dissolved Solids (TDS) of five different samples taken for five major drinking water supplies of Teligati, KUET. All the data collected were compared with different parameters set by WHO and the deviations were observed. From the experimental data, the drinking water supply from BSMRH Hall, a fairly deep tube well (290 feet) situated close to the area, and the water supplied in the outside restaurants met the parameters set by WHO, and the other two only just made the boundary of the parameter. The non-treated drinking water supply from Bangabandhu Sheikh Mujibur Rahman Hall (BSMRH) of KUET and the Shallow tube well situated in the study area were also very close to the allowed range set by World Health Organization (WHO). The BSMRH hall drinking water supply was treated for drinking and the other four supplies were natural. This study confirms the fluctuation of the Drinking water quality index but it rarely surpasses the Water Quality Index (WQI). The treatment method needs minor adjustments and more modern techniques need to be applied. The shallow tube wells need to go out. Further bacteriological and spectrophotometric ion detection methods should be conducted in further studies for the detection of heavy metals like Arsenic, Mercury, and Lead, and also Total Coliform Count.
