Trichloroethylene (TCE) and tetrachloroethylene (PCE) are com mon groundwater contaminants that persist in the environment. An innovative treatment process employing high energy electron beam irradiation has been shown to be an effective process for treating TCE- or PCE-contaminated water, wastewater, and water containing suspended solids. Experiment's conducted at the Electron Beam Research Facility, Miami, Florida, have led to a better understanding of the factors that affect the removal efficiency of TCE and PCE in treated ground water (potable water), secondary wastewater effluent, and raw (untreated) wastewater. The effect of the addition of a hydroxyl radical scavenger, methanol, on the removal of TCE and PCE has also been determined. A quantitative description of TCE and PCE removal efficiency at several carbonate/bicarbonate ion concentrations, and in the presence of 3 percent clay, has also been developed. The reaction by-products have been characterized and chloride ion mass balance determined for irradiated solutions both TCE and PCE.
