Produce water from Ebedei flow station (Delta State) at three points was analysed. Discharged point (A), midstream (B) and downstream (C) were a mile apart. The metal concentration of iron, zinc, cadmium, chromium, nickel, lead and manganese were carried out using standard methods. Lead levels at discharged point and down stream were higher than World Health Organization (WHO) standard limits. The polynuclear Aromatic hydrocarbon were determined using high performance liquid chromatography (HPLC). The total PAHs of sample (A) was 3.63ppm, (B) 52.05 and (C) 59.50 ppm respectively. The pH were within WHO limits of 8.10 and 8.20, conductivity in μs/cm was 20.10 and28.10 within acceptable range. Chloride was between 8, 130.00ppm and 22, 131.53 ppm higher than WHO and effluent discharge limits, while turbidity was between 46ppm-60ppm which was also higher. Hence there is need for holistic monitoring and remediation of produce water in the environment. |
