Highlights for the Week of April 14, 2008

TECHNICAL ASSISTANCE

Technical Assistance to Region I: On March 26, 2008, Dr. Scott Huling (GWERD) provided RPM Joseph Lemay and On-Scene Coordinator Frank Gardner with technical review comments on a proposed in-situ chemical oxidations remedial activity at the Wells G&H Superfund Site in Woburn, MA. There are several technical issues that should be re-evaluated that could result in significant progress in achieving remedial objectives. Issues which are discussed in detail include the need to prepare a conceptual model, effective delivery of the oxidant to the contaminated zones, volume of MnO4- solution injected into each well, and the rationale for this round of injection locations.

Technical Assistance to Region IV: On April 9, 2008, Dr. Eva Davis (GWERD) provided Section Chief David Williams with review comments on documents related to the electric resistance heating (ERH) system to remediate TCE in ground water at the Paducah Gaseous Diffusion Plant in Paducah, KY. General comments were concerned with the results of a ground-water modeling effort, target temperatures, asymptotic TCE recovery, and phasing the implementation of the remediation. Detailed specific comments were provided on a number of issues including the construction phase of the project. Specific concerns were expressed with respect to adherence to normal electrical safety codes. (07-R04-002)
