Bacteriological Quality of River Oroghodo

Abstract

The water quality of river Oroghodo was assessed during bacteriological parameters, which were determined using standard plate count and multiple tube techniques.  Analysis revealed that total heterotrophic bacteria and potential human pathogenic bacteria counts were 5.55 x 10³- 55.65 x 10³ cfu/ml and 4.35 x 10³ – 55.30 x 10³ cfu/ml respectively.  Total coliform, E. coli Enterococcus faecalis and Clostridum perfringens counts ranged from 55 – 900 MPN/100ml, 13 – 388 MPN/100ml, 50 – 240 MPN/100m and 14 – 215 MPN/100ml respectively.  Other bacteria isolated were Pseudomonas species, Klebsiella prenumoniae and Enterococcus species.  The number and kinds of enteric organisms encountered suggest a possible faecal contamination with possible consequent undesirable public health implications.
