Munitions Management (MM) Planning and Support Poster Number 65 – Wednesday F UX-PROCESS UPDATE – FREE SOFTWARE FOR DIGITAL GEOPHYSICAL MAPPING MS. AMY WALKER USAESCH ATTN: ED-CS-G 4801 University Square Huntsville, AL 35816 (256) 895-1604 amy.n.walker@usace.army.mil CO-PERFORMERS: Nick Valleau and Elizabeth Baranyi (Geosoft, Inc.) or the last several years, supported by ESTCP funding under Project MM-0131, the Huntsville Center has worked with Geosoft, Inc. to develop an extensive suite of freely available software tools for the industry to assist with specialised requirements for UXO detection and discrimination. The project provides a standardized tool set to assess data quality, helps improve data processing and analysis, and provides a standard software platform for sharing analysis algorithms. The software package, named UX-Process, operates within Geosoft’s commercial Oasis Montaj data processing environment and currently contains over 70 menu items. UX-Process has been supported and applied in the field for several years, with updated versions released annually. It is available at no cost for U.S. government UXO personnel and their contractors, and existing Oasis Montaj license holders. Requests for this free license can be submitted at: http://www.geosoft.com/pinfo/industry/uxo/uxprocess.asp The UX-Process tools, currently used on UXO projects by contractors and government personnel, improve the utilization of field data by identifying and correcting instrument and acquisition errors and providing documentation of the data quality. In addition, UX-Process provides a consistent and logical structure for adding new target analysis and discrimination capabilities, as they become available. The standard tests and tools developed under this project enable the contractors tasked with collecting, processing and analyzing the data to be more effective in meeting U.S. government data quality standards, and allow the U.S. government to be more efficient in assessing and documenting the quality of the product delivered. This poster will focus on the new developments and updates in the latest release. G-27
Sustainable Infrastructure (SI) Facilities Management — Facility Waste Poster Number 70 – Wednesday APPLICATION OF A BIMETALLIC SOLVENT PASTE TECHNOLOGY FOR PCB REMOVAL FROM OLDER STRUCTURES ON DOD FACILITIES DR. NANCY E. RUIZ NAVFAC Engineering Service Center 1100 23rd Avenue EV411 Port Hueneme, CA 93043 (805) 982-1155 nancy.ruiz@navy.mil CO-PERFORMERS: Dr. Jacqueline Quinn (NASA); Dr. Christian Clausen, Dr. Cherie Geiger, and James Captain (University of Central Florida); Suzanne O’Hara and Thomas Krug (Geosyntec Consultants) R esearchers from the Naval Facility Engineering Command Engineering Service Center (NAVFAC ESC), the NASA-Kennedy Space Center (NASA), the University of Central Florida (UCF) and Geosyntec are working on an ESTCP-funded technology demonstration project (SI-0610) to demonstrate the efficacy of a Bimetallic Treatment System (BTS) to remove and rapidly degrade polychlorinated biphenyls (PCB) found in structural coatings. The BTS technology, which consists of elemental magnesium coated with a small amount of palladium in a solvent solution capable of hydrogen donation, has two functions: (1) to extract PCBs from weathered, decades-old coating material such as paint and (2) to rapidly degrade the extracted PCBs. Prior to 1979, PCBs were extensively used in industrial paints, caulking material and adhesives, as their properties enhanced structural integrity, reduced flammability and boosted antifungal properties. Researchers from NASA and UCF previously demonstrated rapid and complete dechlorination of PCBs in aqueous/solvent systems containing Aroclors 1254, 1260, and 1268 (specific PCB mixtures). Significant, if not complete, PCB extraction and degradation from paint chips with total PCBs as high as 11,000 ppm has been achieved with as little as 48 hours of exposure. The solvent in BTS is used to open but not destroy the polymeric lattice structure of the paint, allowing pathways for PCB movement out of the paint and into the solvent. BTS formulation properties that must be addressed for each site-specific application include viscosity and stability. This project addresses pre-demonstration laboratory testing conducted at two of the demonstration sites and field testing conducted at these demonstration sites, the Vertical Integration Building (VIB), Cape Canaveral, Florida and Badger Army Ammunition Plant, Wisconsin. Pre-demonstration laboratory testing evaluated the concentrations of PCBs in the various materials tested at each facility, including paint metal, wood and concrete and to determine which BTS formulation would work best for each material. Variables evaluated in the demonstration include the substrates on which the PCB coatings have been applied; age of the coatings; adhesion, appearance, and repeat application of BTS; and substrate condition on removal of the BTS and PCB coating. In addition, tests were conducted to evaluate the effect of temperature on the BTS stability and performance. The demonstration goal is to reach PCB concentrations below the Toxic Substances Control Act limit of 50 parts per million (ppm) in the paint on all structures tested. Details of the results from the field demonstration at the VIB and Badger will be presented. G-28
