Bacterial Propagation in Municipal Water and Deep Tube-well Water in Kashipur Locality of Narayanganj City, Bangladesh

Abstract

Present study assessed the pathogenic prevalence in municipal water from 10 supply point and deep tube-well water from 10 deep tube-well point delivered across the Kashipur zone of Narayanganj city, Bangladesh along with their drug resistant pattern through conventional, biochemical and disk diffusion methods. The physico-chemical properties of the deep tube-well water were in satisfactory level, only the samples from location 1, 3, 5 and 9 were exceed the marginal limit for dissolved oxygen however most of the samples of supplied water cross the marginal limit of all parameter (dissolved oxygen ,temperature, pH, electrical conductivity, total dissolve solid and turbidity). Pathogenic bacteria including Escherichia coli and Staphylococcus spp. were found in both supplied water and sewerage authority water (102–106 cfu/ml) and deep tube-well water (102–104 cfu/ml). Additionally, fecal coliforms, Klebsiella spp., Salmonella spp., Shigella spp., Vibrio spp. and Pseudomonas spp. was monitored only among the supplied water. Both of the samples were found to be contaminated with heterotrophic bacteria up to 108 cfu/ml. Most of the bacteria were found to be resistant against more than one drug. Hence, the municipal water of the study area was microbiologically unsafe. The propagation of drug resistant strains was assumed to escalate the public health threat. A survey on public opinions were also conducted to know their daily life style and their concern on water treatment and diseases outbreaks caused by contaminated water.
