Coparative Analysis Of Microbial Load Of Rivers In Ohaji Egbema Local Government

Ohaji Egbema, Imo State were studied over a period of  twelve months to determine the effects of detergent effluent discharges on the aspect of water quality of the river. Water samples from Points A, B and C were screened for microbiological analysis. The results revealed that the level of pollution varied depending on season and that the water quality was acceptable at the upstream (Point A) but became impaired at Points B and C, indicating significant pollution from detergent effluent discharges. The analysis of the microbiological characteristics of water samples from the three points revealed high microbial and faecal contamination with microbial load in the order of 105 and MPN of ≤ 1800. The detergent effluents discharged into Points B and C were found to support the growth of micro organisms such as Escherichia coli, Proteus vulgaris, Streptococcus faecalis, Pseudomonas, Bacillus and Enterobacter species that are pathogenic in nature with higher loads. The results showed that water samples from the river contained toxic substances with higher microbial loads. The detrimental effects of the discharge effluent on the aspect of water quality of Ohaji Egbema River were discussed.
