The safety of washing-reagent-injection technique to remediate subsurface pollution was assessed from the migration and the chemical decomposition efficiencies. Several chlorinated organic solvents could not pass through the vacancy formed by less than 4mmΦ glass beads when the column was saturated with water, while the solvents could pass through even the vacancy formed by 0.1mmΦglass beads. Such effects by the addition of surfactants appear several ways by the different kinds and concentrations of surfactants. It is also observed that the addition of surfactants changes the decomposition reaction route for chloroethylenes; hydrogenolysis reaction which produces the toxic chloroethylenes, becomes dominant route in some case.

从迁移和化学分解效率两个方面评价了注洗法修复地下水污染的安全性。几种氯代有机溶剂不能通过小于4mmΦ玻璃珠形成的空隙，而0.1mmΦ玻璃珠形成的空隙则可以通过。表面活性剂的加入会通过不同种类和浓度的表面活性剂以不同的方式产生影响。表面活性剂的加入改变了氯乙烯的分解反应路线，在某些情况下，产生有毒氯乙烯的氢解反应成为主要途径。
