    abstract = {The microbiological and physico-chemical analysis of the seven borehole waters used by off-campus students of MOUAU were carried out using the Most Probable Number Technique (MPN) for the detection of faecal coliform. Five bacterial species <I>Enterobacter aerogenes</I>, <I>Escherichia coli</I>, <I>Streptococcus faecalis</I>,<I> Staphylococcus aureus</I> and <I>Pseudomonas aeruginosa</I> were isolated together with two fungal specie namely: <I>Mucor racemosus</I> and <I>Aspergillus niger</I>. The Total Heterotrophic Plate Count (THPC) gave a range of 4.7x10<SUP>4</SUP>- 1.82x10<SUP>5</SUP> cfu mL<SUP>-1</SUP> with a mean of 7.89x10<SUP>4</SUP> cfu mL<SUP>-1</SUP> while the Total Coliform Plate Count (TCPC) gave a range of 4.1x10<SUP>3</SUP>-8.6x10<SUP>3</SUP> cfu mL<SUP>-1</SUP> with mean 6.24x10<SUP>3</SUP> cfu. The Presumptive faecal coliform ranged between 0-12 coliform per 100 mL with a mean of 3.57 coliform per 100 mL. Faecal coliform was detected in 57.1% of the water samples. The physico-chemical parameters fell within acceptable limits except for nitrate whose range fell between 65-20 mg L<SUP>-1</SUP> above WHO guidelines of 10 mg L<SUP>-1</SUP>. The findings show that the water samples except those from AL and AG boreholes did not meet WHO standard for drinking. Thus, the bore-holes water and should be treated before drinking.}
