Evaluation of Some Physicochemical Properties and Heavy Metals in Post-Treated Produced Water from Offshore Locations in the Niger Delta Area, Nigeria

This study evaluated the physiochemical properties of produced water. the effective management of offshore e&p wastes is one of the challenges facing the oil and gas industry in nigeria. sampling points were carefully selected to obtain samples that are truly representatives of the post-treated produced water. the ph of the recipient marine water showed compliance with the dpr(department of petroleum resources) standards unlike that of the produced water with a mean value of 6.33.the study concludes with the recommendation that the provisions of environmental guidelines and standard for the petroleum industry (egaspin ) should be followed strictly to facilitate effective management of offshore e&p wastes in nigeria as it is not in line with contemporary international standards as most of the parameters tested and analyzed are not within limit
