Solvent extraction as part of oily soil decontamination process has been including rhamnolipid biosurfactant to be part for seeking its possibility for further implementation. Result of some researchers reported prospect of its implementation due to removal efficiency. This study reported post treatment process assessment to soil residue that remained after the completion of decontamination process. Soil toxicity examined involving Total Petroleum Hydrocarbon (TPH) concentration, Hydrocarbon Structure by using Gas Chromatography-Flame-Ionization Detection (GC-FID), Hydrocarbon bond identification by using Fourier Transform Infra-Red Spectroscopy (FTIR), Toxicity Characteristics Leaching Procedure (TCLP) analysis, Metal and Oxide Metal Content of the residual soil. Germination Index as biological indicator also involved as part of the study to give early indication of impact on residual treated soil. Germination index selected mung bean (Phaseolus radiatus) as object of study. Result showed that at residual soil TPH content could be reduced until 0.78%, there are simplification of hydrocarbon structure after treatment process included weakened of hydrocarbon bonding and concentration observed by FTIR. TCLP result showed residual soil was benign to the environment and Germination Index indicated improvement of mung beans germination after decontamination process.
