Thermal Desorption/Ultraviolet Photolysis Process Research, Test and Evaluation Performed at Johnston Island for the USAF Installation Restoration Program. Volume 1. Technical Report

Abstract

The objective of this effort was to examine the feasibility of using a thermal desorption/ultraviolet destruction technology to treat Herbicide Orange (HO)-contaminated soil at Johnston Island (JI), in the Pacific Ocean. This technology is not considered incineration, so it is attractive from a regulatory standpoint. The IT Corporation pilot-scale thermal desorption/ ultraviolet photolysis (TD/UV) process was used to successfully treat 2180 pounds of soil contaminated with HO and 2, 3, 7, 8-tetrachlorobenzo-p-dioxin (TCDD). The TD/UV process volatilizes organic compounds from the soil matrix (coral at JI); collecting the desorbed organic contaminants in a solvent; and treating the contaminant-laden solvent with high-intensity UV photolysis. Keywords: Herbicide Orange, Dioxin, Analytical Methods, Soil Sampling, Hazardous Materials. (MJM).
