Message #44: October 2000 Since September 1, TechDirect gained 247 new subscribers for a total of 9,154. Welcome to everyone just joining TechDirect. After more than three years, we have passed the 9000 subscriber mark. I continue to be surprised how many people across the world are interested in information about site remediation and characterization technologies. I hope these e-mails continue to keep you abreast of new information in technology development and deployment. We know that TechDirect generates document downloads and it is a very effective system for pointing people to information resources. However, we have very little understanding of how these documents and resources aid in the conduct of your work. If there have been resources in past issues of TechDirect that have been particularly useful, feel free to let us know. Mention of non-EPA documents or presentations does not constitute a U.S. EPA endorsement of their contents, only an acknowledgment that they exist and may be relevant to the TechDirect audience. Documents A Guide to Developing and Documenting Cost Estimates During the Feasibility Study (EPA-540-R-00-002). This report was prepared by the U.S. EPA Office of Emergency and Remedial Response and the U.S. Army Corps of Engineers' Hazardous, Toxic, and Radioactive Waste Center of Expertise. It provides protocols for developing cost estimates of remedial alternatives during the remedial investigation/feasibility study process to improve the consistency, completeness, and accuracy of cost estimates. The document presents clear procedures and expectations, a checklist of cost elements, and example formats. It also identifies resources for estimating costs during the feasibility study (July 2000, 76 pages) plus several appendices.

TechDirect: October 1, 2000 1 of 4 clu-in.ora/newsletters ------- Potential Applicability of Assembled Chemical Weapons Assessment Technologies to RCRA Waste Streams and Contaminated Media (EPA 542-R-00-004). This report was published by the U.S. EPA Technology Innovation Office. It provides an evaluation of the potential applicability of Assembled Chemical Weapons Assessment (ACWA) technologies to RCRA waste streams and contaminated media found at RCRA and Superfund sites. The information in this report is intended to provide site managers information on the potential uses of ACWA technologies and to help technology providers better understand the potential market for those and similar technologies (August 2000, 88 pages).

Innovations in Site Characterization Case Study: Site Cleanup of the Wenatchee Tree Fruit Test Plot Site Using a Dynamic Work Plan (EPA 542-R-00-009). The Wenatchee Tree Fruit Research and Extension Center site contained soils contaminated with organochlorine pesticides, organophosphorus pesticides, and other pesticides due to agriculture-related research activities conducted from 1966 until the mid-1980s. The U. S. Army Corps of Engineers used a dynamic work plan guided by field analyses to seamlessly integrate the site characterization and cleanup portions of the project. Characterization, excavation, and segregation of contaminated soil was based on the results of immunoassay (IA) test kits for DDT and cyclodiene pesticides. An initial pilot test and then continuing evaluation of data comparability between the IA methods and fixed laboratory pesticide results allowed the USACE team to develop site-specific IA kit action levels that guided on-site decision-making. Characterization, cleanup, and closure was accomplished within a single 4-month field mobilization, and the entire project cost ($589K) was about half the cost ($1.2 million) estimated according to a more traditional site characterization and remediation scenario relying on multiple rounds of field mobilization, sampling, sample shipment, laboratory analysis, and data assessment (August 2000, 46 pages).

UXO Detection at Jefferson Proving Ground Using Ground-Penetrating Radar (ERDC/CRREL TR-00-005). This document was published by the US Army Corps of Engineers Cold Regions Research Laboratory. Ground-penetrating radar (GPR) was used to detect UXO and nonordnance on the 40-acre site at Jefferson Proving Ground, Indiana. The report discusses the results TechDirect: October 1, 2000 2 of 4 clu-in.ora/newsletters ------- of that effort. It concluded that GPR is effective for finding targets in this type of soil to no more than 2-m depth (April 2000, 38 pages).

Innovative Technology Summary Report: Electrical Resistance Tomography for Subsurface Imaging (DOE/EM-0538). This report was produced by the U.S. Department of Energy. Electrical Resistance Tomography allows site investigators to view two- or three-dimensional electrical resistivity images of the subsurface on an on-site computer terminal within minutes of data acquisition. ERT For Subsurface Imaging technology has been successfully demonstrated for monitoring remediation processes, detecting potential leaks under high-level waste tanks, measuring moisture movement in fractured rock, and for verifying the effectiveness of subsurface barriers (June 2000, 34 pages).
