Abstract: Physicochemical properties and heavy metals of oilfield wastewater of Etelebou flow station in Bayelsa State was carried out for a period of 3-months. Oilfield wastewater samples from various pits (pit 1, pit 2, pit 3. Camp pit 1 and camp pit 2) in the station were analyzed using standard procedures. The physicochemical parameters analyzed and their ranges were; pH 6.55- 11.15, temperature 22.25- 34.35oC, turbidity 20 – 4742 NTU, TDS 163 – 6653 mg/l, TSS 28 – 4575.5 mg/l, COD 32.5 – 927.5 mg/l, BOD5 16 – 443 mg/l, DO 0.6 – 6.15 mg/l, salinity 93.5 – 5147.5 mg/l, Conductivity 321 -11750 Us/cm, The range for heavy metals were chromium 0.09 to 0.16 mg/l, lead 0.47 to 1.01 mg/l, iron 1.63 to 5.62 mg/l, copper 0.01 to 0.03 mg/l and zinc 0.21 to 0.47 mg/l. Some physicochemical parameters and heavy metals observed during the study were statistically significant in some parameters and insignificant in other parameters. Some values obtained for the various parameters exceeded the recommended limits for effluent/wastewater before discharge. The study showed that the oilfield wastewater contains inorganic constituents that could be harmful if discharged into the surrounding soil or leached into groundwater. This could result to ecotoxicological problem in the environment.
