• Chlorinated ethylenes (tetrachloroethylene (PCE), trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-DCE), and 1,1-dichloroethylene (1,1-DCE)), which are soil and groundwater contaminants, were degraded by chemically reacting with hydrogen peroxide, tungstate, and ammonium salt at 25°C. The degradation reaction progressed in a neutral to slightly basic environment of pH 6-9. The degradability of the ethylenes was in the order of 1,1-DCE > TCE > cis-DCE > PCE; and this showed degradation characteristics different from those of conventional oxidizing agents (such as potassium permanganate). Furthermore, treatment by this reaction was applied to groundwater sample from a contaminated site, and all chlorinated ethylenes in the water sample were degraded except for PCE.
