Desires of contaminated soil and groundwater remediation have been apparently increased in recent years in Japan. However, more cost-effective and environmentally friendly remediation measures are being expected because of very high financial load on subsurface contaminants remediation. Environmental risk is firstly assessed using RBCA (risk-based corrective action) and remediation measures are compared in this research to evaluate its applicability to Japanese situation. At a trichloroethylene (TCE) contaminated site, based on detected TCE content at source zone and site hydro-geological condition, Tire 2 risk assessment results showed that risk of down-gradient groundwater ingestion receptor exceeds the target risk on current condition. Remediation target was then discussed by considering present receptor and potential receptor, and also risk assessment results were compared with present Environmental Quality Standard (EQS), including soil leaching standard and groundwater standard. The results show that, method like RBCA can give a more rational and cost-effective remediation target. However, to introduce risk management concept into environmental management, it is still necessary to get social acceptance supposing contaminated soil will be very well managed and no any environmental problems will be caused even the contaminated soil is left in-situ.
