The oil production operations create large quantities of contaminated water which is known as “Produced Water”. All the produced water in the Nafoora oil field dispelled to water pit without treatment and /or re-used in injection. Due to concerns over the effects of oil production activities on groundwater quality, heavy metals, physical and chemical properties were analyzed in 7 samples collected from Gas Oil Separation Plant GOSP and Shallow Water Well from the field. A combination of newly collected and historical data was used to determine whether produced water have mixed with groundwater. Then, comparing the results with standards of World Health Organization WHO and Food and Agriculture FAO. The analysis results of physical and chemical properties shows that the pH values in all GOSPs stations ranging between 4.4 -7.2 and high concentrations of Total Dissolved Salts TDS (28000 to 101000 ppm) and Chloride CL concentrations ranging between 111600 ppm to 136700 ppm and have as well high EC values (122200 to 568200 uS/cm). The Nafoora oil field contains heavy metals such as Hg, Cr, Zn, Cu, Cd, Ag and Pb. Three minerals with concentration above WHO and FAO standards; Cr, Cu and Cd. While Hg, Zn, Ag and Pb have concentration in acceptable range. The results indicated the produced water mixed with the ground water. According to WHO and FAO standards the associated production water from all GOSPs stations unsuitable for drinking or agriculture. Without proper treatment the produced water is harmful as source of drinking water and other daily activity. Consequently, the produced water requirements to be handled and fulfill the quality standards before being discharged to the environment or reused in the EOR process. |
