Download or read book Field Test of Single Well DNAPL Characterization Using Alcohol Injection written by and published by . This book was released on 1996 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils and groundwater beneath an abandoned process sewer line in the A/M Area of the Savannah River Site (SRS) contain elevated levels of volatile organic compounds, specifically trichloroethylene (TCE) and tetrachloroethylene (PCE), two common chlorinated solvents. These compounds have low aqueous solubilities, thus when released to the subsurface in sufficient quantity, tend to exist as immiscible fluids or nonaqueous phase liquids (NAPLs). Because chlorinated solvents are also denser than water, they are referred to by the acronym DNAPLs, or dense non-aqueous phase liquids. Technologies targeted at efficient characterization or removal of DNAPL are not currently proven. The authors performed injection/extraction characterization tests in six existing wells in A/M Area. Water concentrations for TCE and/or PCE in these wells ranged from 0% to 100% of solubility. For each test, small amounts of solubilizing solution were used to try to confirm or deny the presence or absence of DNAPL in the immediate vicinity of the well screen.

Download or read book Groundwater and Soil Cleanup written by National Research Council and published by National Academies Press. This book was released on 1999-11-21 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive, up-to-date review of technologies for cleaning up contaminants in groundwater and soil. It provides a special focus on three classes of contaminants that have proven very difficult to treat once released to the subsurface: metals, radionuclides, and dense nonaqueous-phase liquids such as chlorinated solvents. Groundwater and Soil Cleanup was commissioned by the Department of Energy (DOE) as part of its program to clean up contamination in the nuclear weapons production complex. 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.

Download or read book Surfactants and Cosolvents for NAPL Remediation A Technology Practices Manual written by Donald F. Lowe and published by CRC Press. This book was released on 1999-03-26 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Facility (AATDF). One of the project goals is the development of reduction strategies for nonaqueous phase liquids (NAPLs) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvent for in situ remediation. It is targeted to decision makers and anyone concerned with the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents , the possible results, design, and operation. It includes case studies, step-by-step guidance, and project cost work sheets. The successful results of the AATDF research, as documented Surfactants and Cosolvents for NAPL Remediation, are an invaluable contribution to the future of subsurface remediation. Without source NAPL reduction, the alternative is decades of plume management through pump-and-treat.
Download or read book DNAPL Site Evaluation written by James W. Mercer and published by CRC-Press. This book was released on 1993-04-29 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNAPL Site Evaluation covers long-term contamination of ground water by DNAPL (dense non-aqueous phase liquids) chemicals. The book develops a framework for planning and implementing DNAPL site characterization activities. It provides detailed methods to identify, characterize, and monitor sites and analyzes their utility, limitations, risks, availability, and cost. Methods to interpret contaminant fate and transport are identified, and new site characterization methods are assessed. DNAPL Site Evaluation will maximize the cost-effectiveness of site investigation/remediation by providing the best information available to describe and evaluate methods to be used for determining the presence, fate, and transport of subsurface DNAPL contamination. The book will be a useful reference for groundwater professionals and environmental regulatory personnel.

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.

Download or read book DNAPL Characterization Using the Ribbon NAPL Sampler written by and published by . This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ribbon NAPL Sampler (RNS) is a direct sampling device that provides detailed depth discrete mapping of Non Aqueous Phase Liquids (NAPLs) in a borehole. This characterization method provides a yes or no answer to the presence of NAPLs and is used to complement and enhance other characterization techniques. Several cone penetrometer deployment methods are in use and methods for other drilling techniques are under development. The RNS has been deployed in the vadose and saturated zones at four different sites. Three of the sites contain DNAPLs from cleaning and degreasing operations and the fourth site contains creosote from a wood preserving plant. A brief description of the process history and geology is provided for each site. Where available, lithology and contaminant concentration information is provided and discussed in context with the RNS results.
