Physico-chemical and microbiological assessment of drinking water of the selected restaurants in Mymensingh district of Bangladesh

Water is essential for living organisms their survival. Access of adequate and safe water a basic need human beings. In adequacy unsafe supply may cause various health problems. This study was designed with view to assessing physicochemical properties drinking collected from different restaurants at Mymensingh sadar. this case, electrical conductivity (EC), total dissolved solids (TDS), pH, oxygen (DO), biological demand (BOD), arsenic (As), iron (Fe) lead (Pb) were measured. Furthermore, Microbiological assessments samples carried out. For achieving the microbiological assessment, methods heterotrophic plate count (HPC) coliform (TCC) applied. The mean value EC, TDS, DO, BOD, As, Fe, Pb 682.38 µS cm-1, 201ppm, 7.11, 4.98 mg/L, 1.72 0.005 ppm, 0.181 ppm 0.000 respectively. According standard toxicity not detected in all samples. All above mentioned parameters present within permissible limits. most cases concentrations some Fe considered as toxicants due higher noted. highest found Ganginapar sample (1.2×107 CFU/ml) noted C. K. Ghosh road (13 coliforms/100 ml). Therefore, examined quality indicate that sadar suitable drinking. Although identified presence fecal coliforms indicates contamination feces water. One among studied contaminated which very harmful It be concluded hygienic purposes.
