Bacteriological Investigation of Kolo Creek Surface Water Status in Ogbia Local Government Area of Bayelsa State, Central Niger Delta, Nigeria

Abstract

The study investigates the bacteriological 
characteristics of the Kolo Creek surface water in 
Ogbia Local Government Area of Bayelsa State, 
the central Niger Delta. The main objective of the 
study was to assess the seasonal variation of 
microbial load in the Creek in relation to human 
health, since the Creek remain the major source of 
drinking water. Samples were collected both in the 
rainy or wet season (July) and dry season 
(December). The bottles were fixed before they 
were taken for sampling. The samples were taken 
with the mouth of the bottles facing the water 
current and were covered under the water to 
avoid atmospheric contamination. The samples 
were preserved with ice-park. Analysis of 
variance (ANOVA) was used to analysis the dataset. The values from the laboratory analysis were 
compared with WHO and FEPA standards for 
drinking water. The findings of the study reveals 
that the Kolo Creek is highly polluted with feacal 
coliform. The total microbial load were higher 
than WHO and FEPA standards for all the 
samples. The total coliform count and the 
Escharichia coli were also higher than the values 
of the WHO and FEPA standards. Therefore, Kolo 
Creek surface water requires basic treatment 
before use
