Description:
The two reports summarized here describe development of the alkali metal (polyethylene gylycolate (APEG) chemical technology to dechlorinate hazardous hydrocarbons in soils and its application at four demonstration sites: field-scale application to contaminated soils on the island of Guam; pilot-scale demonstration in Moreau, New York; and drum-stored contaminated materials at the Bengart & Memel site in New York and in Omaha, Nebraska. The Omaha site involved tetrachlorodibenzo-p-dioxiri (TCDD) in waste herbicides. Equipment for the field-scale application on Guam included a stearji-jacketed mixer, a steam-generating plant, and a condensate collection system. Approximately 15 yd3 of contaminated soil (with concentrations averaging 3535 ppm Aroclbr 1260) were batch treated with potassium polyethylene glycoiate (KPEG). The polychlorinated bipheny (PCS) concentrations were reduced by more than 99%, with no individual PCB congener exceeding 2 ppm. The reports provide detailed information about preparation of contaminated soils before treatment, equipment and reagents used during treatment, and analyses done before, during, and after treatment. Potential users are given sufficient information of the KPEG process to ascertain which version of the process is best suited for a particular site.
