**10. Conclusions**

Surfactants-enhanced soil remediation represents an effective alternative to traditional remedial framework and has been successfully incorporated into various ex-situ and in-situ remediation technologies. There is a great potential to develop novel synthetic and biosurfactants that will exhibit higher biodegradability, less toxic, higher removal efficiency, more economical and more recyclable. Noteworthy are the prospects of the development and commercial production of mixed surfactants with low CMC containing additives mixed that will reduce remediation cost and increase remedial performance.
