Abstract

The microbiological quality of drinking water is a concern to consumers, water suppliers, regulators and public health authorities. The greatest risk from microbes in water is associated with consumption of drinking water which is focally contaminated. Although other sources are also significant. The potential of drinking water to transport microbial pathogens to great numbers of people causing subsequent illness is well known. The pathogens that are transmitted through water are diverse and is a major concern of consumers. The water is usually treated with disinfectant before it is distributed however, sometimes insufficient dose of disinfectant or leakage of distribution pipelines may gain the entry of pathogens in to drinking water and become a major cause of outbreaks. The number of outbreaks that has been reported throughout the world indicates that transmission of pathogens by drinking water remains a significant cause of illness. By considering this in the present study bacteriological analysis was carried out for indicator organisms i.e. total coliform and fecal coliform (E.coli) by MPN method and using Endo agar and IMViC tests. A total of 60 samples were collected from six different sites from a period of May 2010 to October 2010 five sites from consumer’s tap of A B C D and E ward and one from water reservoir at Balinga lifting site. Results indicated that all samples were found contaminated with total coliforms as well as fecal coliforms in the month of June, July and August. Sample from E ward showed positive results throughout the study period and also the counts were higher in E ward samples. The present study indicated the need for improvement in water treatment plant and or distribution pipeline system.
