Water samples were collected from wells, bore holes and some
streams at various locations within Akungba-Akoko, Ondo
state. Pour plate technique was used for the estimation of
Total bacterial count and Coliforms count of the water
sources. Mean heterotrophic bacterial counts (cfu.ml) ranged
from 1.0 x 104 in A.A.U.A storage tank to 122 x
104 in Oroke well. Total coliforms counts (cfu/ml)
ranged from 0.01 x 104 in A.A.U.A storage tank to
36 x 104 and 38 x 104 in Oroke well
and stream, respectively.
Microorganisms isolated from the different water sources
include Escherichia coli, Klebsiella spp,
Bacillus spp, Bacillus cereus, Proteus spp, Streptococcus
spp, Pseudomonas spp., Flavobacterium spp., Streptococcus
feacalis, Pseudomonas aeroginosa, and Staphylococcus aureus.
This study thus revealed that some indicator and
pathogenic group of organisms like E. coli, S.
feacalis and B. cereus constituting 13.34% each of
the total number of microorganism isolated were largely
encountered in the water sources from this area, hence,
there is need for proper monitoring of the water sources to
avert outbreak of epidemic disease.
The pH of water sources ranged from pH 5.52 and 5.87 in
Ilale borehole 2 and Ilale well respectively to pH 7.67 in
Igbelu well. The temperature recorded range from 23 - 28°C
for the sample sources. The wide variation in
Physico-chemical parameters like pH from the neutral point
signifies presence of contaminants that may favour the
spread of some aetiologic agents of diseases that could be
controlled through proper health delivery systems
Key words:
Akungba- Akoko, microbiological, Ondo state, ground water,
surface water.
