Bacteriological Quality Assessment of Water from Epie Creek, Niger Delta Region of Nigeria

摘要

This study evaluated the bacteriological quality of water samples from Epie creek, Niger Delta. Water samples were collected from five different locations (Akenfa, Agudama-Epie, Tombia, Opolo and Biogbolo) in two seasons viz: dry i.e. January and February and wet season i.e. May and June, 2016). The samples were analyzed following standard protocols. Results from the water quality ranged from 5.38-6.74 log cfu/ml (total heterotrophic bacteria), 1.72-2.54 log cfu/ml (Salmonella-shigella counts), 2.01-2.83 log MPN/100ml (total coliform), 1.55-2.22 log MPN/100ml (faecal coliforms). Analysis of variance showed that there was significance difference (P<0.05) in total and fecal coliform for location, months and interaction for total and fecal coliform, and no significance difference (P>0.05) for total heterotrophic bacteria and Salmonella-Shigella counts. The bacterial isolates were Pseudomonas, Enterobacter, Bacillus, Citrobacter, Erminia, Klesbsiella, Shigella, Salmonella, Proteus, Serratia, Micrococcus, Corynebacterium species, Staphylococcus aureus and E. coli. The monthly and spatial distribution similarity interaction ranged from 88.00 - 96.00% and 55.56 - 86.96% respectively, being above critical level of significance = 50% for similarity index. The values showed that anthropogenic activities in the creek are having an impact on the water quality.
