B -- TECHNICAL SUPPORT FOR FIELD DEMONSTRATION OF SURFACTANT ENHANCED ACQUIFER REMEDATION AT NEUTRAL BUOYANCY (SEAR-NB) POC Connie Osborne, Contract Specialist, (208) 526-0093, Brad Bauer, Contracting Officer, (208) 526-0090 E-MAIL: Click here to contact the Contract Specialist via, osbornch@id.doe.gov. This notice rescinds the Notice of Contract Award issued on June 8, 1998, for Technical Support for Field Demonstration of Surfactant Enhanced Aquifer remediation at Neutral Buoyancy (SEAR-NB), and correctly indicates an intent to award other than full and open competition per FAR Part 6.302-1 to Duke Engineering & Services (DE&S) for the Technical Support for Field Demonstration of Surfactant Enhanced Aquifer remediation at Neutral Buoyancy (SEAR-NB). The services required is part of a larger research effort funded by DOE and EPA to implement the first field demonstration of a new innovative groundwater remediation technology called surfactant enhanced aquifer remediation at neutral buoyancy (SEAR-NB). The objective is to cleanup groundwater contaminated with dense nonaqueous phase liquids (DNAPL) using the new technology at a U.S. Environmental Protection Agency (EPA) superfund site in New Hampshire. To date, preliminary estimates of the extent and concentrations of DNAPL in the subsurface have been made using vertical profiles. Wells have been established and the aquifer tested. The services required by the DOE of the contractor relate to the following remaining activities, which have yet to be accomplished. A pre-flood partitioning interwell tracer test (PITT) will need to be designed, implemented, and the results analyzed to characterize the DNAPL source. A SEAR-NB flood will then be designed and implemented; and finally, a post-flood PITT will be designed, implemented, and the results analyzed to assess flood performance. The specific technical support services required under this request for services to support the successful field demonstration of SEAR-NB at the EPA superfund site. DE&S is the only private company that has successfully achieved greater than 98 % cleanup efficiency of DNAPL using SEAR PITTs will also be used in this project for determination of source characterization and performance acceptance, because EPA has accepted them as the performance assessment tool for this project. DE&S in collaboration with Dr. Gary Pope at University of Texas have a patent pending for the PITT technology. Failure to take advantage of their experience and successes would jeopardize the success of this project. The estimated value of this award is $650,000. This is not a solicitation. See Notice 22.
