Evaluation of the Efficacy of Soil Remediation by Enhanced Recovery and Aeration Technique in Ogale Community in Eleme Local Government Area, in Rivers State

Study evaluated soil remediation by enhanced natural attenuation as option to improve soil nutrients in oil impacted communities in Eleme local government area of Rivers state.Experimental method was deployed for the study and sources of data were both primary and secondary.The study was anchored on environmental quality theory.Some of the objectives of the study includes; Evaluation of the efficacy of the soil remediation technique on soil quality in the study area; Determine the extent of variation in soil physicochemical properties in the study area, Identification of the presence of heavy metals in the study area and outlining of interaction existing between remediated soil through enhanced natural attenuation and impacted soil in the study area.Study analysed the variations in soil physiochemical properties, heavy metals, micro-bacteria count and TPH at 50cm, 150cm and 250 cm depths across the impacted soil sample KH1, treated soil sample KH2 and unimpacted soil KH3 (control).Descriptive statistical technique was deployed for analysis via SPSS23.0version.Results showed that amongst others, that the highest recorded P H value of 6.99 was at 250cm distance of unimpacted soil in KH13 and a decrease in Total Nitrogen content from unimpacted soil by 0.017mg/kg.Studyrecommends adoption of enhanced natural attenuation as an option to improve on soil impacted by oil pollution in the study area.Study also recommends full implementation of environmental laws and regulations by responsible agencies in order to achieve the full potentials of bioremediation of oil impacted soil in the study area.
