Subsurface barrier technologies as potential interim actions for Department of Energy underground storage tanks

Westinghouse Hanford Company administers the US Department of Energy (DOE) Underground Storage Tank Integrated Demonstration (UST-ID) Program, which is designed to demonstrate technologies for the retrieval, treatment, and closure to DOE USTs and tank waste at five facilities throughout the US. In February 1992, Bovay Northwest conducted an UST workshop for Westinghouse Hanford. The scope of the workshop included a variety of applied subsurface barrier technologies that could be installed around an UST or series of USTs. This paper summarizes the information presented in the workshop. Once selected, screened technologies will be tested in the field in a full-scale demonstration and development project (also funded by the UST-ID program).
