Book Long Term Monitoring of Permeable Reactive Barriers   Progress Report

Download or read book Long Term Monitoring of Permeable Reactive Barriers Progress Report written by and published by . This book was released on 2001 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to conduct collaborative research to evaluate and maximize the effectiveness of permeable reactive barriers (PRBs) with a broad-based working group including representatives from the U.S. Department of Energy (DOE), U.S. Department of Defense (DoD), and the U.S. Environmental Protection Agency (EPA). The Naval Facilities Engineering Service Center (NFESC) and its project partner, Battelle, are leading the DoD effort with funding from DoD's Environmental Security Technology Certification Program (ESTCP) and Strategic Environmental Research and Development Program (SERDP). Oak Ridge National Laboratory (ORNL) is coordinating the DOE effort with support from Subsurface Contaminant Focus Area (SCFA), a research program under DOEs Office of Science and Technology. The National Risk Management Research Laboratory's Subsurface Protection and Remediation Division is leading EPA's effort. The combined effort of these three agencies allows the evaluation of a large number of sites. Documents generated by this joint project will be reviewed by the participating agencies' principal investigators, the Permeable Barriers Group of the Remediation Technologies Development Forum (RTDF), and the Interstate Technology and Regulatory Cooperation (ITRC). The technical objectives of this project are to collect and review existing field data at selected PRB sites, identify data gaps, conduct additional measurements, and provide recommendations to DOE users on suitable long-term monitoring strategies. The specific objectives are to (1) evaluate geochemical and hydraulic performance of PRBs, (2) develop guidelines for hydraulic and geochemical characterization/monitoring, and (3) devise and implement long-term monitoring strategies through the use of hydrological and geochemical models. Accomplishing these objectives will provide valuable information regarding the optimum configuration and lifetime of barriers at specific sites. It will also permit development of site-specific monitoring and performance plans, thus optimizing operation and maintenance (O & M) costs while increasing confidence of both regulators and end users in applying the barrier technology.

Book Long Term Performance of Permeable Reactive Barriers

Download or read book Long Term Performance of Permeable Reactive Barriers written by K.E. Roehl and published by Gulf Professional Publishing. This book was released on 2005-04-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: While extensive research has been performed on many technological aspects of permeable reactive barriers and a number of contaminants have so far been successfully treated by PRB systems, long-term performance has not been extensively considered and little is known about the processes influencing long-term behaviour. This gap in our knowledge is all the more disadvantageous as design life has a decisive influence on the economic viability of PRBs. The book describes methods for evaluation and enhancement of the long-term performance of PRB systems, especially of those targeting heavy metals, specifically uranium, and organic contaminants by sorption and/or precipitation mechanisms. Major topics in the book are: - Selection and characterisation of suitable reactive materials - Characterisation of the relevant contaminant attenuation processes - Developing new contaminant-binding chemical compounds ("ligands") - Accelerated testing methods to assess the long-term performance of the attenuation mechanisms in PRBs - Evaluation of the influence of site characteristics on PRB performance - Monitoring of existing and new field installations - Coupling of electrokinetic techniques and PRB systems - Large-scale laboratory and field tests and their results It addresses the long-term performance of PRBs, an important feature of this novel remediation technology, systematically. It deals extensively with heavy metal removal, with special emphasis on uranium. A number of case studies, experiences with large-scale modelling and test site experiments provide insight into the practical application of the results. This volume will contribute to the science underpinning groundwater remediation, and this will result in the improvement of quality of life and health and safety.* A systematic approach to investigating the long-term performance of permeable reactive barriers* Development of new contaminant-binding chemical compounds ("ligands"), accelerated testing methods to assess the long-term performance, and efficiency enhancing electrokinetic techniques* Extensive data and information on a Hungarian uranium mining facility; once a carefully kept secret of the Soviet Union

Book Permeable Reactive Barrier

Download or read book Permeable Reactive Barrier written by Ravi Naidu and published by CRC Press. This book was released on 2018-10-08 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.

Book Investigating the Potential for Long term Permeable Reactive Barrier  PRB  Monitoring from the Electrical Signatures Associated with the Reduction in Reactive Iron Performance

Download or read book Investigating the Potential for Long term Permeable Reactive Barrier PRB Monitoring from the Electrical Signatures Associated with the Reduction in Reactive Iron Performance written by J. Baker and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work was to conduct laboratory and field experiments to determine the sensitivity of low frequency electrical measurements (resistivity and induced polarization) to the processes of corrosion and precipitation that are believed to limit permeable reactive barrier (PRB) performance. The research was divided into four sets of experiments that were each written up and submitted to a peer-reviewed journal: [1] A laboratory experiment to define the controls of aqueous chemistry (electrolyte activity; pH; valence) and total zero valent iron (Fe0) available surface area on the electrical properties of Fe0 columns. [2] A laboratory experiment to determine the impact of corrosion and precipitation on the electrical response of synthetic Fe0 columns as a result of geochemical reactions with NaSO4 and NaCO3 electrolytes. [3] Laboratory experiments on a sequence of cores retrieved from the Kansas City PRB to determine the magnitude of electrical and geochemical changes within a field active PRB after eight years of operation [4] Field-scale cross borehole resistivity and induced polarization monitoring of the Kansas City PRB to evaluate the potential of electrical imaging as a technology for non-invasive, long-term monitoring of indicators of reduced PRB performance This report first summarizes the findings of the four major experiments conducted under this research. The reader is referred to the four papers in Appendices 1-4 for a full description of each experiment, including motivation and significance, technical details, findings and implications. The deliverables of the project, including the publications, conference papers and new collaborative arrangements that have resulted are then described. Appendices 5-6 contain two technical reports written by co-PI Korte describing (1) supporting geochemical measurements, and (2) the coring procedure, conducted at the Kansas City PRB as part of this project.

Book Cost and Performance Report   Evaluating the Longevity and Hydraulic Performance of Permeable Reactive Barriers at Department of Defense Sites

Download or read book Cost and Performance Report Evaluating the Longevity and Hydraulic Performance of Permeable Reactive Barriers at Department of Defense Sites written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Defense (DOD) Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) sponsored a project to assess performance and longevity issues at DOD permeable reactive barrier (PRIB) sites. The goal of this project was to evaluate short- and long-term performance issues associated with permeable reactive barriers (PRBs) installed at several United States Department of Defense (DoD) sites, A PRB is a passive, in situ technology, in which natural groundwater flow brings contaminants into contact with a reactive or adsorptive material that removes the dissolved contaminants and protects down gradient receptors. Therefore, PRBs have potentially lower life cycle costs compared to an equivalent pump-and-treat system. The key regulatory driver for the technology is the proven ability of common barrier materials, such as elemental iron, to meet groundwater cleanup standards for many common contaminants, including chlorinated solvents and certain heavy metals. Regulatory interest in this project was driven by the two challenges involved in implementing PRBs, namely, their longevity and hydraulic performance. The Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) sponsored this project. The Naval Facilities Engineering Service Center (NFESC) was the lead agency for the DoD project. Eattelle, under contract to NFESC, planned and implemented the technical scope and has prepared this report to summarize the results.

Book Design Guidance for Application of Permeable Reactive Barriers for Groundwater Remediation

Download or read book Design Guidance for Application of Permeable Reactive Barriers for Groundwater Remediation written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Battelle, under contract to the Air Force, has prepared a comprehensive update to the February 1997 version of a design guidance document for the proposed use of site managers, contractors, and regulators. The design guidance covers permeable barrier application to sites with contaminated groundwater. The document does not purport to replace the scientific judgment of the on-site engineer or hydrogeologist, but provides guidance on the issues and options that need to be considered based on the current understanding of the technology. The guidance addresses design, construction, and monitoring of permeable barriers in various hydrogeologic settings. This update includes the lessons learned during the design, construction, and monitoring of a permeable reactive barrier at Dover AFB, DE, as well as progress made at other sites. It also includes the advances in the technology since the completion of the previous version of the report.
