Description:
This document is an evaluation of the performance of the Toxic Treatments (USA), Inc., (TTUSA) in situ steam/hot-air stripping technology and its applicability as an on-site treatment technique for hazardous waste site soil cleanup of volatile and semivolatile contaminants. Both technical and economic aspects of the technology were examined. A demonstration of the TTUSA stripping technology was conducted beginning in the fall of 1989 at the GATX Annex Terminal site located at the Port of Los Angeles, California. Operational data and sampling and analysis information were carefully compiled to establish a data base against which other available data, as well as the vendor’s claims for the technology, could be compared and evaluated. Conclusions concerning the technology’s suitability for use in stripping the range of contaminants at this test site were reached, and extrapolations regarding applications at other sites with different contaminants and soil types were made. The following conclusions were derived primarily from the Demonstration Test results and supported by other available data: (1) the process removed volatile organic compounds at an average efficiency of approximately 85% from the contaminated soils tested; (2) the technology reduced the level of semivolatile compounds in the soil by approximately 50%; (3) there was no evidence of significant downward migration of contaminants based on qualitative testing; (4) fugitive emissions from the soil during and after treatment were low; and (5) the process is capable of removing volatile organic compounds in situ in relatively short time periods with competitive economics.
