Abstract
A comparative study of the portability of sample from Owo main water corporation and some selected borehole water sample within Owo metropolis. The water sources were assessed for microbiological quality and physico-chemical properties (temperature, odour, colour and pH). The samples were investigated for microbial load using Eosine Methylene Blue agar (EMB) Nutrient agar (NA) and Mannitol Salt agar (MSA). The physicochemical analysis of the water was also determined. Bacillus subtilis, Escherichia coli, Proteus species, Enterobacter species and Staphylococcus aureus were isolated and identified from the samples. The total viable count ranges from 10 x 101 – 5.7 x 102 cfu on Mannitol salt agar for sample from water Corporation and Folahanmi borehole sample respectively. The investigation revealed that samples from Folahanmi and Rugipo contain all the isolated microorganisms while sample from Iselu contain Escherichia coli, Proteus species and Enterobacter species only. The pH of the water sample ranged from 4.80 to 7.37 Rugipo borehole sample and sample from water corporation respectively. All the samples appear colourless and odourless. Of the water samples examined it was observed that only the sample collected from water corporation conform with the specification of Environmental Protection Agency.
