Seasonal Variation of Physico-Chemical and Bacteriological Characteristics of Sagbama, River Central Niger Delta, Bayelsa State, Nigeria

Abstract

This research work focused on the seasonal variation of physico-chemical and bacteriological characteristics of Sagbama River, in Bayelsa State Nigeria. Samples were collected in both dry and raining seasons. Four samples were collected for each of the seasons. The sample collected were taken to the laboratory for physico-chemical bacteriological analysis within eight hours. A two-ways ANOVA statistical technic SPSS was used to test the hypotheses. The results of the study show that, the season effect. Since the p-value is less than 0.05 the null hypothesis is rejected and conclude that there is significant difference in the number of unit’s composition in seasonal variation of Sagbama river surface water. For the physico-chemical parameters, since the p-value is less than 0.05 we reject the null hypothesis and up-held the alternate hypothesis that there is a significant difference in the number of unit’s composition in physico-chemical parameters of Sagbama river water. For interaction, since the p-value is less than 0.05, the alternate hypothesis is accepted that there is an interaction (seasonal and physico-chemical parameter) effects.For the bacteriological characteristics, since the p-value is less than 0.05we reject null hypothesis and conclude that there is significant difference in the number of units’ compositions in bacteriological characteristics of Sagbama river surface water. And finally for interaction effect, since the p-value is greater than 0.05 we accept null hypothesis, that there are no interaction effects. The findings of the study revealed that the Sagbama River is polluted. The researchers therefore recommended that water from this source must be properly treated before consumption.
