Bacteriological Quality of Drinking Water from Different Locations in Anambra State, Nigeria

Abstract

The work described the bacteriological quality of drinking water obtained from distributors, vendors and retailer at three different locations in Anambra State Nigeria. Twelve samples were assessed using membrane filtration technique and serial dilution method. Some selective media were used which include Pseudomonas Agar (PSA) for detection of Pseudomonas aueroginosa, Salmonnella Shigella Agar (SSA) for detection of Salmonella typhii and Shigella. Biochemical tests were used to identify the following bacteria: Pseudomonas aueroginosa, Staphylococcus aureus, E. coli, Bacillus sp and Enterobacter. Five samples were positive in pseudomonas agar while three samples were positive in salmonella shigella agar. Therefore producers, distributors and hawkers of packaged water need to be educared on how to disinfect their products with solar radiation, store and handle packaged water.
