Available in PDF, EPUB and Kindle. Book excerpt: A meeting on ''Transport of Contaminants in the Subsurface: Role of Organic and Colloidal Materials'' was held on October 5-9, 1986, in Manteo, North Carolina. The meeting was part of the series of International Seminars on the Subsurface held by the Subsurface Transport Program o f the Office of Health and Environmental Research of the U.S. Department of Energy. The meeting was organized by Frank Wobber (OHER/DOE) and John McCarthy (Oak Ridge National Laboratory). The purpose of the meeting was to review current knowledge about the role played by colloids on the mobility of contaminants in the subsurface environment, and to identify important long-term research needs in this area. Participants included senior researchers in this field from national laboratories, government agencies, universities, and research institutes in four countries. Recent findings on the occurrence and nature of colloidal material in the subsurface as well as on the association of colloids with organic, metal, and radionuclide contaminants were presented and discussed. Field studies have demonstrated that colloidal particles do move through aquifers and that radionuclides have been transported much further than predicted due to their association with mobile colloids in the groundwater. The consensus of the meeting was that colloids do occur in the subsurface environment, are capable of binding organic and inorganic contaminants, and do alter the mobility of Contaminants. A major difficulty in understanding and predicting the role of colloids is their heterogeneous nature that hampers precise chemical characterization. Clay and metal oxide colloids can be formed or dissolved due to changes in solution chemistry in the aquifer. Organic colloids have variable and diverse functional groups, making it difficult to predict their association with metal and radionuclide contaminants Some important advances were reported toward understanding the assembly of organic colloids and the nature of their interactions with organic contaminants. Major research needs identified by the participants included studies in real systems on the occurrence of colloids in subsurface environments, and more rigorous characterization of the physical and chemical properties of the colloidal material. Methods for sampling colloids need to be improved to avoid production of artifacts during collection. In summary, the meeting concluded that colloidal material is important in contaminant transport and that further research in this area will significantly improve our capacity to predict the movement of energy-related contaminants in subsurface environments.
Book Synopsis Contaminants in the Subsurface by : National Research Council
Download or read book Contaminants in the Subsurface written by National Research Council and published by National Academies Press. This book was released on 2005-03-23 with total page 370 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.

Book Synopsis Natural Attenuation for Groundwater Remediation by : Commission on Geosciences, Environment, and Resources
Download or read book Natural Attenuation for Groundwater Remediation written by Commission on Geosciences, Environment, and Resources and published by National Academies Press. This book was released on 2000-08-31 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, officials responsible for clean-up of contaminated groundwater have increasingly turned to natural attenuation-essentially allowing naturally occurring processes to reduce the toxic potential of contaminants-versus engineered solutions. This saves both money and headaches. To the people in surrounding communities, though, it can appear that clean-up officials are simply walking away from contaminated sites. When is natural attenuation the appropriate approach to a clean-up? This book presents the consensus of a diverse committee, informed by the views of researchers, regulators, and community activists. The committee reviews the likely effectiveness of natural attenuation with different classes of contaminants-and describes how to evaluate the "footprints" of natural attenuation at a site to determine whether natural processes will provide adequate clean-up. Included are recommendations for regulatory change. The committee emphasizes the importance of the public's belief and attitudes toward remediation and provides guidance on involving community stakeholders throughout the clean-up process. The book explores how contamination occurs, explaining concepts and terms, and includes case studies from the Hanford nuclear site, military bases, as well as other sites. It provides historical background and important data on clean-up processes and goes on to offer critical reviews of 14 published protocols for evaluating natural attenuation.

In addition to a review of remediation technologies, the book describes new trends in regulation of contaminated sites and assesses DOE's program for developing new subsurface cleanup technologies.
Book Synopsis Non-equilibrium Conditions During Organic Contaminant Mobilization, Transport and Degradation in the Subsurface by : Markus Wehrer
Download or read book Non-equilibrium Conditions During Organic Contaminant Mobilization, Transport and Degradation in the Subsurface written by Markus Wehrer and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes determining the fate of organic contaminants in the subsurface are often characterized by non-equilibrium conditions. This habilitation treatise explores the kinetic characteristics of the processes influencing the fate of organic contaminants in the subsurface employing computational-, laboratory- and field experiments. In the first part, release and transport processes of hydrophobic contaminants from multicomponent non-aqueous phase liquids (NAPLs) are examined in 5 individual studies. These comprise a review of the literature on the fate of contaminants at manufactured gas plants, laboratory experiments and modeling of the release kinetics of polycyclic aromatic hydrocarbons (PAHs) from aged and fresh tar phases, and a field study of a crude oil contaminated aquifer employing geophysical, hydrogeochemical and microbiological methods. The second part comprises three studies, which explore transport and degradation kinetics of hydrophilic compounds, which are used as deicing chemicals at airports. In this part, a laboratory percolation experiment was evaluated with a numerical model and the degradation of the deicing chemicals propylene glycol and formate under field conditions was characterized in lysimeters, employing, among other methods, electrical resistivity tomography (ERT). The studies show that multiple interdependencies exist between contaminant transport time-scales and time-scales of mobilization and degradation. Solubilization of PAHs from tar oils was diffusionally highly restricted with extremely long equilibration times. Hydrophobic compounds are often subject to mobilization and transport as colloids, which was observed in all experimental studies with aged NAPLs. Degradation kinetics of deicing chemicals were found to be dependent on a dynamic reaction of the biomass in column experiments and did not agree with first-order kinetics. The field lysimeter experiments showed that the ratio of degradation time-scale to transport time-scale determines the fate of propylene glycol. As a consequence, non-equilibrium transport conditions resulted in rapid discharge of large amounts of propylene glycol from the topsoil. The results have consequences for experimental procedures aiming for process identification and parameter quantification of mobilization, transport and degradation of organic contaminants. For a realistic estimation of risk of exposure, natural attenuation and biological remediation, experimental and numerical evaluation including transport conditions is inevitable.

Book Synopsis Innovations in Ground Water and Soil Cleanup by : National Research Council
Download or read book Innovations in Ground Water and Soil Cleanup written by National Research Council and published by National Academies Press. This book was released on 1997-10-21 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on ground water and soil cleanup address only the technologies themselvesâ€"not why new technologies are or are not developed. Innovations in Ground Water and Soil Cleanup takes a holistic approach to the entire field, addressing both the sluggish commercial development of ground water and soil cleanup technologies and the attributes of specific technologies. It warns that, despite cleanup expenditures of nearly $10 billion a year, the technologies remain rudimentary. This engaging book focuses on the failure of regulatory policy to link cleanup with the financial interests of the company responsible for the contamination. The committee explores why the market for remediation technology is uniquely lacking in economic drivers and why demand for innovation has been so much weaker than predicted. The volume explores how to evaluate the performance of cleanup technologies from the points of view of the public, regulators, cleanup entrepreneurs, and other stakeholders. The committee discusses approaches to standardizing performance testing, so that choosing a technology for a given site can be more timely and less contentious. Following up on Alternatives for Ground Water Cleanup (NRC, 1994), this sequel presents the state of the art in the cleanup of various types of ground water and soil contaminants. Strategies for making valid cost comparisons also are reviewed.
