July The synopsis is meant to show rough performance levels under a variety of different conditions. No detailed site descriptions were provided. Two different reagent loading rates were used. Unit cost estimates for soil treatment are not provided. Dioxin tests are more costly due to the complicated analytical procedures.
The scope of work at the NCBS site was to determine the kinetics of processing dioxin contaminated soil using 30 kg batches in a modified gallon drum reactor unit. However, no significant correlation appears to exist between performance as measured by the amount of contaminant remaining and reagents used, reagent ratios, time, temperature, or reagent loading for all the treatability studies.
Contaminant destruction appears to take place in-situ or in soil slurry form. Refer to the document for more information. Waste at the Montana Pole site is generated as the oily phase of groundwater pumped from foot deep wells; after separation by decantation, approximately 3-percent pentachlorophenol PCP in a diesel-like oil is obtained at the rate of gpd.
This site represents an inactive wood treating facility located on a acre, sloping abandoned mining site, where contamination by dioxins CDDs and furans CDFs has reached an adjacent creek, including groundwater and surface soil.
Because of the presence of these potentially highly toxic CDDs and CDFs, the raw oil could not be transported off-site for incineration. Oil samples were obtained from the site and transported to the Brehm Laboratory at Wright State University in Dayton, Ohio, for analysis. Subsequently, parametric studies were conducted to determine treatment conditions to effect optimum decontamination.
