The present study focuses the assessment of physicochemical and microbial quality of drinking water collected from several sources namely, residential halls, mess and restaurants at Santosh, Tangail. Present study also assesses the antibiotic resistance pattern of these bacteria. physicochemical parameters such as water temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), chloride (Cl-) and nitrate (NO3-) were ranged from 28-300C,7.05-7.64, 713-785 µScm-1, 203-463mg/L, 222-398 mg/L, 220-425 mg/L, 0.158-0.87 mg/l, respectively. Again total viable count (TVC), total coliform count (TCC), Escherichia coli, Salmonella shigella (SS) were ranged from 1.3×106-4.0×107cfu/100ml, 1.05×105- 6.4×106cfu/100ml, 7.2×103-1.1×105 cfu/100ml, 6.1×103-5.3×104cfu/100ml respectively. It was revealed that two isolates (Escherichia coli, Salmonella and Shigella spp.) in six examined plates were resistant to Ampicillin and Amoxicillin, and highly sensitive to Ciprofloxacin. The tested physicochemical parameters except total hardness were below the permissible limit stipulated by WHO. On the contrary, most potentially dangerous discover was that the level of microbiological parameters exceeds the WHO standards. From questionnaire survey it was also evident that most of the people have been suffering from some waterborne diseases. Considering the above findings present study suggests that necessary measure should be taken to have safe a drinking water for all concerns.
