Assessment of water quality around Odi, Sampou and Agbede Upper Nun River, Bayelsa State Nigeria

Abstract

Assessment of water physico-chemical parameters of surface water in a section of the Upper Nun River, around Agbere, Sampou and Odi, in Bayelsa State, Nigeria was carried out. Water samples were collected biweekly in triplicates for three months using water sampling bottles. The physicochemical water quality parameters determined in this study includes Salinity, Electrical Conductivity (EC), Total dissolved solids (TDS), Total suspended solids (TSS), Total alkalinity (TA), Total hardness (TH), Turbidity, pH, Chloride (Cl), Sulfate (SO4), Nitrate (NO3), Iron (Fe), Manganese (Mn), Magnesium (Mg), Bicarbonate (HCO3), Calcium (Ca), Sodium (Na) and Potassium (K). Salinity and pH, were measured in-situ while others were analysed in the laboratory. The study used the Completely Randomized Design. A one-way ANOVA was used to show variance between the means at (p
