Bacteriological Analysis of Drinking Water in Zamfara North Senatorial District, Nigeria: Brief Overview | Chapter 4 | Theory and Applications of Microbiology and Biotechnology Vol. 3
Provision of portable drinking water is of public health
concern especially in developing countries where this is unavailable. Microbes
are ubiquitous and are known to contaminate materials including food and water.
Microbial contamination cannot be detected by sight, smell or taste. Basic
laboratory tests are the best way to tell if coliform organisms are present as
they can be there with no appearance or taste difference. The microbiological
quality of drinking water (DW) in Zamfara North Senatorial Zone was examined. A
total of 16, two each from each of eight common brands of sachet water in the
area were bought from water vendors, and were examined for total bacteria load,
total coliform and presence of bacteria species using standard microbiological
techniques. The result showed that the total viable count of bacteria in all
the samples ranged from 6.0×102 CFU/ml to 4.0×108 CFU/ml. Total coliform was
1.8×107 MPN/100 ml for all the tested samples. The organisms isolated were
Pseudomonas maltophila, Escherichia coli, Citrobacter freundii, Pseudomonas
pseudomollia, Salmonella typhi, Shigella species, and Pseudomonas dimineta.
Prevalence of different isolates revealed that Pseudomonas, C. freundii, S.
typhi and E. coli were predominant in comparison to Shigella species. The
present study revealed that the microbial quality often exceed World Health
Organization (WHO) and Food and Agricultural Organization (FAO) allowable limit
of 1.0x102 CFU/ml for potable water and Standards Organization of Nigeria (SON)
maximum permissible level of 10 CFU/ml (total coliform) and 0 CFU/100 ml. The
high microbial isolates and load may have contaminated the water from the
environment. These microbes found in the drinking water sources are known to
cause several diseases. Present study indicate that water testing would ensure
the supply and availability of contamination-free drinking water; and awareness
amongst people towards sanitation and hygienic conditions for storage of
drinking water is needed to keep away the use of contaminated water. The
present study suggests that drinking water sources should be properly treated
prior to consumption using appropriate methods; so as to reduce the occurrence
of waterborne diseases.
