CHAPTER FOUR
4.0 RESULTS
The water samples investigated in this study were mainly analysed for bacteriological and mycological contaminations. A total of fifty (50) samples were collected from regions such as wells, dams, rivers, streams, mosques, hostels, and public boreholes in Malete, Elemere and Asomu. The pH of the water samples (50) fall between pH 7-8.3. Water samples were analysed and categorized into two different groups. Untreated water consisted of water whose sources include; Wells, dams, river and streams. Treated water samples were gotten from public boreholes, hostels and mosques.
Out of 20 untreated water samples, 14 (70%) were found positive for the presence of coliforms while out of 30 treated water samples, 9 (30%) were found positive for the same. The samples which were found positive for coliform presumptive test underwent confirmatory test. Out of 23 positive samples, 7 were confirmed for the presence of faecal coliforms. In addition, 5 water samples were found positive for Streptococcus faecalis. Load of Viable aerobic bacteria per ml of the water sample was determined (Table 1).
Twenty seven (54%) specimens showed no growth on the plate count agar and were mostly from treated water samples. Escherichia coli (30%) was the major pathogen among the other bacterial isolates followed by Streptococcus faecalis (22%) and Staphylococcus aureus (13%). Other organisms were Pseudomonas Spp. (9%), enteric bacteria (13%) and environmental bacteria (13%). Some of the samples contained more than one isolate. All the water samples investigated for the presence of Salmonella, Shigella and Vibrio cholerae were found negative (Table 2).

CHAPTER ONE - [ Total Page(s): 2 ]Hence, it is essential to check the quality of the available drinking water from various sources. In view of this present study was designed to analyze the microbiological quality of the available drinking water from various sources like food stalls, tea stalls, supply water, packaged water to facilitate the examination of level of contamination and finally hence the risk associated with their consumption. 1.2 Statement of the ProblemThe most common and widespread dang ...

CHAPTER THREE - [ Total Page(s): 4 ]CHAPTER THREE3.0 MATERIALS AND METHODS3.1 The Study AreaThis study was conducted in Malete town in the Malete district of Moro Local Government Area of Kwara State. Kwara State is one of the 36 States that constitute the Federal Republic of Nigeria. It is bounded in the West by Republic of Benin; in the North by Niger State, by Kogi State in the East; and by Ekiti, Oyo and Osun States in the South. There are 16 Local Government Areas in the State and major towns include Offa, Omu-ara ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 2 ]CHAPTER FIVE5.0 DiscussionAn acceptable pH for drinking water is between pH 6.5 to pH 8.5, recommended by WHO as a guideline value and in the absence of a distribution system acceptable range may be broader. However, the water samples examined in this study were within the acceptable pH range. For the presumptive coliforms test, the WHO guideline for both treated and untreated water samples is 0/100 ml (WHO, 2009), but in an occasional untreated water sample 3 coliform/100 ml are allowed o ...
