Dynamic Underground Stripping Engineering Demonstration Project: Construction, operation and engineering results

The Dynamic Underground Stripping Project demonstrates cost-effective, rapid cleanup of localized underground plumes, often the result of leaking underground storage tanks. The technique combines the complementary technologies of subsurface steam injection and electrical resistance heating. The engineering demonstration phase of this project was completed on a clean, uncontaminated site with well- characterized geology. The Clean Site is located in Livermore, California at the US Department of Energy's Sandia National Laboratory (SNL). The experience gained at the Clean Site will be applied to clean up an 8,000 to 12,000 gallon gasoline spill, approximately 500 yards to the northwest, at the Lawrence Livermore National Laboratory (LLNL)
