PCT No. PCT/CH93/00217 Sec. 371 Date Jul. 1, 1994 Sec. 102(e) Date Jul. 1, 1994 PCT Filed Sep. 3, 1993 PCT Pub. No. WO94/05438 PCT Pub. Date Mar. 17, 1994A process for immobilizing organic and inorganic pollutants in contaminated soil materials in which partial remediation areas of a reconstruction site are purified by an on-site procedure presenting no danger to the surrounding ground water. With a clay mineral content of greater than or equal to 60 wt. %, both organic and inorganic pollutants are reduced and immobilized by washing with an alkylammonium compound. When the clay mineral content is less than 60 wt. %, a bentonite compound is added in controlled amounts and the pollutants are immobilized or further washed out.
