Abstract:

The objective of this effort was to examine the feasibility of using a thermal desorptionultraviolet TDUV destruction technology to treat Herbicide Orange HO -contaminated soil at the Naval Construction Battalion Center NCBC, Gulfport, Mississippi. The IT Corporation pilot -scale TDUV apparatus was used to successfully treat 1700 pounds of sandy loam, cement stabilized, soil that had been contaminated with HO and 2,3,7,8 tetrachlorobenzo-p-dioxin TCDD. The TDUV process volatilizes organic compounds from the soil matrix collects the desorbed organics in a solvent and, destroys the contaminants with high-intensity ultraviolet light. The desorption process occurs between 850 to 1150 degrees F. in a nitrogen atmosphere to prevent combustion of the organics. Analysis of feedstock showed TCDD levels ranged from 233-272 parts per billion ppb. Concentration in the treated soil, measured as the sum of all dioxinfuran congeners, was less than 1ppb, the USAF criterion.
