BACTERIOLOGICAL ANALYSIS OF BORE HOLE WATER FROM OUTLET WITHIN FEDERAL UNIVERSITY GUSAU
Abstract
Microbes are ubiquitous and are known to contaminate materials, including food and water. Isolation and identification of Salmonella typhi from borehole water in Federal University Gusau was conducted to determine its potability. Triplicate samples were collected from ten (10) different boreholes and analyzed. The total bacterial load and Salmonella-Shigella count were determined using the plate count technique. The average counts were as follows: total bacteria ranged from 1.34 CFU/ml to 2.10 CFU/ml and Salmonella-Shigella count was from 0 CFU/ml. Salmonella typhi was not able to be isolated from all samples. This study indicated that the bacteriological quality exceeded the World Health Organization (WHO) allowable limits of 0 CFU/100ml for total bacterial load count due to the underground aquifers and free of Salmonella-Shigella. Therefore, we recommend that borehole water sources be adequately treated before consumption to reduce the risk of waterborne diseases.
