Abstract

The study had as aim to assess the bacteriological quality of drinking water in the study area. Fifty-three water samples from various sources in Njinikom sub division were sampled. The Multiple Tube fermentation Technique (MTFT) was used. Presumptive coliform counts were obtained by the most probable number of coliforms per 100ml of water by making reference to the McCrady’s probability table after combination of various positive and negative results. Positive tubes were sub cultured on MacConkey agar and biochemical media for Escherichia coli identification. Of the 53 samples tested 13 (24.5%) had E. coli in addition to other coliforms which is a probable indication of fecal contamination, 35(66.1%) had only other coliforms without E. coli in varying degrees. Only 5 (9.4%) were without coliforms or E coli. Gross bacteria pollution was observed for unprotected springs. Mainly alternative water sources such as underground springs, brooks and rivers were largely contaminated indicating closeness to toilets and external contaminants. Measures should be taken to protect drinking water sources, extend municipal water supply coverage and prohibit domestic animals from entering drinking water courses.
