This book was released on 1997 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1996 and 1997, five separate partitioning interwell tracer tests (PITTs) were conducted as part of two separate surfactant-enhanced aquifer remediation (SEAR) demonstrations targeting DNAPL (primarily TCE) at Operable Unit 2 (OU2), Hill Air Force Base, Utah. These PITTs were used as a DNAPL characterization tool to accurately determine: 1.) the total aquifer volume swept; 2.) the total amount of DNAPL present in the swept aquifer volume; and, 3.) the average residual saturation present. PITTs were conducted before and after each SEAR demonstration to provide remediation performance assessments and were hydraulically controlled without using sheetpile walls. The successful implementation of field-scale PITTs required an engineering design strategy using conventional characterization activities, laboratory studies, and UTCHEM modeling. The volume sampled by each PITT was on the order of an average of 6500 cu ft (14,000 gallon pore volume). Tracer recoveries ranged from 79% to 92%, indicating that, within experimental error, all of the injected tracers were recovered. The method of temporal moments was used to analyze each PITT, and the resulting DNAPL volume estimates were in close agreement with other measurements (e.g. SEAR DNAPL recoveries and core data estimates). Thus, in sandy alluvium, PITTs are very accurate estimators of DNAPL volumes, and provide an excellent characterization and performance assessment tool for DNAPL remediation efforts. Based on the success of these PITTs, the USAF is currently conducting large-scale PITTs to characterize the entire DNAPL source zone at OU2.

This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2 DANNY D. REIBLEI AND KATERINA DEMNEROVA 1 Hazardous Substance Research Center/South and Southwest, Louisiana State University, Baton Rouge, LA 70803 2 Department of Biochemistry and Microbiology, Institute of Chemical Technology, Prague, Czech Republic On May 24, 2001, a total of 102 students and lecturers participated in an Advanced Study Institute (ASI) sponsored by the North Atlantic Treaty Organization (NATO) under our direction. The Institute was focused on in situ and onsite management of contaminated sites. The objective of the Institute was to balance state of the art science with techniques for field application of a variety of technologies for in situ assessment and remediation of contaminated sites. Many of the lecturers were drawn from the ranks of the Hazardous Substance Research Centers, multi-university consortia that have been funded by the US Environmental Protection Agency to conduct research and technology transfer designed to promote risk-based management and control of hazardous substances for the nation. The Centers have made special contributions to the areas of in situ and onsite assessment and remediation of contaminated sites. Such approaches have the potential for being significantly less expensive than other assessment and remediation approaches while maintaining accuracy and effectiveness. Cost-effective remedial and management approaches that are also effective in minimizing exposure and risk to human health and the environment are a critical need throughout the world but particularly in Eastern Europe and the former Soviet Union where resources that can be devoted to environmental cleanup are especially limited.

This book was released on 1997 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work plan (WP) was prepared by Parsons Engineering Science, Inc. (Parsons ES) to define the scope of work (SOW) and procedures required to demonstrate that remediation by natural attenuation (RNA) is occurring in groundwater contaminated with chlorinated aliphatic hydrocarbons (CAHs) at Operable Unit 2 (OU 2) at Hill Air Force Base (AFB), Utah. To meet this goal, this WP presents a preliminary conceptual model, based on a review of available data, and provides suggested protocols to fill the identified data gaps necessary to develop a more thorough conceptual model of groundwater flow and RNA at OU 2. For the purposes of this WP, RNA is defined as a management strategy that relies on natural mechanisms to bring about a reduction in the total mass of contamination in the subsurface, and to control receptor exposure risks associated with this contamination. Natural attenuation is defined by the United States Environmental Protection Agency (USEPA) Offices of Research and Development (ORD) and Solid Waste and Emergency Response (OSWER), as follows: The biodegradation, dispersion, sorption, volatilization, and/or chemical and biochemical stabilization of contaminants to effectively reduce contaminant toxicity, mobility, or volume to levels that are protective of human health and the ecosystem. As suggested by this definition, there are destructive and non-destructive mechanisms of natural attenuation. Of these processes, biodegradation is the only mechanism working to transform contaminants into innocuous byproducts. During biodegradation, indigenous microorganisms work to bring about a reduction in the total mass of contamination in the subsurface without the addition of nutrients. Patterns and rates of natural attenuation can vary markedly from site to site depending on governing physical and chemical processes.
Book Synopsis Chlorinated Solvent Source Zone Remediation by : Bernard H. Kueper
Download or read book Chlorinated Solvent Source Zone Remediation written by Bernard H. Kueper and published by Springer Science & Business. This book was released on 2014-04-22 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to help engineers and scientists better understand dense nonaqueous phase liquid (DNAPL) contamination of groundwater and the methods and technology used for characterization and remediation. Remediation of DNAPL source zones is very difficult and controversial and must be based on state-of-the-art knowledge of the behavior (transport and fate) of nonaqueous phase liquids in the subsurface and site specific geology, chemistry and hydrology. This volume is focused on the characterization and remediation of nonaqueous phase chlorinated solvents and it is hoped that mid-level engineers and scientists will find this book helpful in understanding the current state-of-practice of DNAPL source zone management and remediation.

This book was released on 1994 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is composed of two phases and has the objective of demonstrating surfactant-enhanced aquifer remediation (SEAR) as a practical remediation technology at DOE sites with ground water contaminated by dense, non-aqueous phase liquids (DNAPLs), in particular, chlorinated solvents. The first phase of this project, Laboratory and Pilot Field Scale Testing, which is the subject of the work so far, involves (1) laboratory experiments to examine the solubilization of multiple component DNAPLs, e.g., solvents such as perchloroethylene (PCE) and trichloroethylene (TCE), by dilute surfactant solutions, and (2) a field test to demonstrate SEAR technology on a small scale and in an existing well.

Download or read book Contaminants in the Subsurface written by National Research Council and published by National Academies Press. This book was released on 2005-04-23 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.
