Characterization of surface and ground water with reference to microbiological study in Akungba-Akoko, Ondo State

摘要

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.
