ABSTRACT

Waterborne diseases are still emerging global concerns, hence the need for continuous assessment of drinking water quality to ensure safe consumption. This study focuses on determining the bacteriological properties of borehole water samples distributed within Federal college of Education (F.C.E) Katsina, Katsina State, Nigeria by assessing the bacterial and coliform counts of the water distributed and the characterization of the bacteria present. The bacteriological quality of the water samples was analyzed using standard methods. A total of 20 samples were collected from ten different sites within college community. A total of six (6) bacteria isolates were identified using the bioMerieux vitek 2 system. They include Acinetobacter baumannii, Pseudomonas aeruginosa, Pseudomonas florescens, Chromobacterium violanceum, Dermacoccus nishinomiyaensis and Kocuria kristinae. The total bacterial counts and total coliforms were 0.56 – 2.31 × 10² cfu/mL and 6.50 – 34.00 cfu/100mL respectively. Faecal coliforms were absent in all the samples analyzed. Analysis of variance (ANOVA) revealed significant differences in the values of the bacterial counts obtained and no significant differences in the faecal coliform counts at P < 0.05. The water quality within the college community fell within the permissible standards of the WHO. More so, the bacterial isolates demonstrated complete susceptibility to Ciprofloxacin and Gentamicin which could serve as drug of choice for the treatment of these pathogens. The study recommends continuous surveillance of the water supplies and regular disinfection of the water in other to keep up with quality of the water supplies.
