ABSTRACT

Produced water from four Delta State Community flow-stations [Ogulaha (A), Sokobolor (B), Iyokiri (C) and Okirika (D)] 10 miles apart were analyzed.  They contain 35.26ppm polycyclic aromatic hydrocarbon for A, 4.57ppm for B, 60.68 for (C) and 53.00 for (D).  pH values were 8.10 for A, 8.20 for B, 8.10 for C and 8.10 for D, tuibidity values were 63NTU for A, 51 for B, 47 for C and 66 for D.  BOD and COD were (310.00, 121.00, 201.31 and 231.21)ppm and (810.00, 710.00, 913.00 and 810.00) ppm respectively for samples A, B, C, and D.  Total organic carbon (mg/l) was 30.00, 154.00, 23.00 and 240.00 for the samples A, B, C and D.  The metal concentrations of iron, zinc, nickel, cadmium and lead were higher than accepted limits of World Health Organisation (WHO) and National Environmental Standard and Regulation Enforcement Agency (NESREA) while copper, chromium and manganese were within acceptable limits.
