The authors have invented an in-situ replacement method using a water jet technique which has possibility of removing only contaminated soil and conducted a construction experiment at a VOCs (Volatile organic compounds) contaminated site. Another experiment of a emediation metbod was also conducted at the same site : it installed reactive substances containing iron particles, which could dilute the concentration of chlorinated organic compounds, into an only contaminated aquifer by the water jet. The results showed : (1) the technique could remove only contaminated soil and replace it with nonhazardous material; (2) by increasing the density of injected material for replacement, almost 100% replacement efficiency could be achieved; (3) the permeable reactive substances were successfully installed at a designed rate of iron particles; and (4) it could reduce VOCs effectively as had expected.
