PHYSICO-CHEMICAL PROPERTIES OF SOIL SAMPLES IMPACTED BY HYDROCARBONS FROM SELECTED SITES IN THE ....

The physio-chemical parameters of soil samples from selected hydrocarbon-impacted sites in the Niger Delta region were determined in this study. Standard sampling and analytical techniques were used. Sand, Silt, Clay, TOC (percent), pH, EC (s/cm), Av.P (mg/kg), Magnesium (mg/kg), Potassium (mg/kg), Sodium (mg/kg), and Calcium (mg/kg) were all measured. The results showed that the physio-chemical properties of soil in hydrocarbon-impacted sites measured after the biostimulation remediation technique used in Oguta community, the enhanced land farming technique used in Omuwei community, and the enhanced natural attenuation technique used in Oporoma community were all within the WHO permissible limit, with the exception of conductivity (98.62-125.71), which needs to be investigated further. It was also discovered that the physical and chemical qualities of soil in selected impacted sites differed between sample stations. Based on these data, it was determined that the variances seen in this study were caused by the intrinsic environmental conditions at the time of sample collection. It is consequently advised that relevant organisations use the WHO guidelines to continually monitor the values of these indicators.
