    This study was undertaken to determine the bacteriological quality of three selected sources of drinking water sold in Ilorin metropolis. Representative water samples were collected from 87 sources consisting of 60 boreholes, 20 packaged sachet water and 7 river water samples from seven different locations across three Local Government Areas in Ilorin metropolis. The samples of water were collected in sterile McCartney bottles, placed in ice-packed flasks and immediately transferred to the laboratory for bacteria isolation, determination of bacterial load (total bacterial and coliform counts) and biochemical identification respectively. Results from this study showed that the most common bacteria isolates obtained were Staphylococcus aureus (33 isolates), Proteus species (28 isolates) and Salmonella species (26 isolates). Other bacteria isolates obtained included Klebsiella species, Pasteurella species, Bacillus species and Escherichia coli. Furthermore, results showed that river water samples had the highest bacterial count with an average of 8.56 x 102colony forming units (CFU)/100 ml, while the packaged sachet water samples had the least colony count with an average of 2.32 x 102CFU/100 ml. The total coliform counts of the borehole and packaged sachet water were within the WHO limit for portable drinking water although the total bacterial count was higher. The distribution patterns of the isolates based on sampling sites revealed that most of these organisms were encountered at Ilorin West. The disparity of the bacteriological quality of the different water sources could be related to the varying level of exposure to contaminants within and across the sampling locations. The results of this study emphasize the need for periodic assessment of water quality for safety purposes.

    Physical Properties, Correlation and Regression Analyses of Potable Water in Ilorin, Nigeria.
    (Journal of Research in Forestry, Wildlife & Environment, Department of Forestry Wildlife and Range Management, University of Agriculture, Makurdi., 2020) Oludairo, O. O.; Aiyedun, J. O.; Olorunshola, I. D.; Bale, J. O. O.; Akintola, O. O.
    Water is said to be wholesome if it is fit to use for drinking, cooking, food preparation or washing without any potential danger to human health. This research aimed to determine the potability of water from borehole, sachet and river in Ilorin, Nigeria using physical parameters, assess the correlation between the parameters and carry out regression analysis of the parameters. Water samples were randomly collected from the three Local Government Areas (LGA) in Ilorin to assess physical properties and carry out correlation and regression analyses. Temperature of water samples were between 29 ⁰C – 31.4 ⁰C while pH ranged between 6.42 and 7.90. Correlation coefficient was +0.989 while regression analysis estimated optimal temperature of 30 ⁰C for pH of 7.03. The physical parameters of water in the study area fell within recommended range. There was strong direct relationship between the physical parameters studied. Further studies could consider investigating other physical and chemical parameters involving larger number of samples.
