Available in PDF, EPUB and Kindle. Book excerpt: This report provides an engineering analysis of, and status report on, selected enhancements for soil vapor extraction (SVE) treatment technologies. The report is intended to assist project managers considering an SVE treatment system by providing them with an up-to-date status of enhancement technologies; an evaluation of each technology's applicability to various site conditions; a presentation of cost and performance information; a list of vendors specializing in the technologies; a discussion of relative strengths and limitations of the technologies; recommendations to keep in mind when considering the enhancements; and a compilation of references. The performance of an SVE system depends on properties of both the contaminants and the soil. SVE is generally applicable to compounds with a vapor pressure of greater than 1 millimeter of mercury at 20EC and a Henry s Law constant of greater than 100 atmospheres per mole fraction. SVE is most effective at sites with relatively permeable contaminated soil and with saturated hydraulic conductivities of greater than 1 x 10 or 1 x 10 centimeter per second (cm/s). SVE by itself does not effectively remove contaminants -3 -2 in saturated soil. However, SVE can be used as an integral part of some treatment schemes that treat both groundwater and the overlying vadose zone. Enhancement technologies should be considered when contaminant or soil characteristics limit the effectiveness of SVE or when contaminants are present in saturated soil. The five enhancement technologies covered in this report are as follows and are described in the following subsections: * Air Sparging * Dual-phase Extraction * Directional Drilling * Pneumatic and Hydraulic Fracturing * Thermal Enhancement.
Download or read book Air Sparging for Site Remediation written by Battelle Memorial In and published by CRC Press. This book was released on 1994-02-23 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of aquifer contamination remains one of the greatest challenges facing environmental scientists and engineers. Air sparging, a technique unknown until recently, has emerged with increasing application frequency as an alternative to both the pump-and-treat technology and conventional in situ bioremediation for treating this problem. This book, featuring contributions from the world's most experienced air sparging practitioners, conveys the latest practical experience and information from North America and Europe. Air Sparging for Site Remediation presents an overview of air sparging in general and detailed information on particular air sparging technologies and their applications. The book examines the application of the technology to a variety of contaminants, including hydrocarbons, pesticides, nitrates, and chlorinated hydrocarbons. In addition, these specific topics and more are discussed:

Download or read book Alternatives for Ground Water Cleanup written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.
Download or read book Chemical Treatment written by William C. Anderson and published by Springer. This book was released on 1995-06-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph on chemical treatment is one of a series of eight on innovative site and waste remediation technologies that are the culmination of a multi organization effort involving more than 100 experts over a two year period. It provides the experienced, practicing professional guidance on the application of innovative processes considered ready for full-scale application. Other monographs in this series address bioremediation, soil washing/soil flushing, solvent chemical extraction, stabilization/ solidifica tion, thermal desorption, thermal destruction, and vacuum vapor extraction. 7. 7 Chemical Treatment The term chemical treatment, as used in this monograph, refers to the use of reagents to destroy or chemically modify target contaminants by means other than pyrolysis or combustion. The monograph addresses processes that chemically treat contaminated soils, groundwaters, surface waters, and, to a limited extent, concentrated contaminants. Chemical treatment is a means of converting hazardous constituents into less environmentally ob jectionable forms in order to meet treatment objectives. This monograph addresses substitution, oxidation, and chemical precipi tation processes. It addresses processes within these classes that are suffi ciently advanced for full-scale application. There are a number of emerging technologies within these classes that are in the research or an early devel opment stage, not yet ready for full-scale application, that appear to be very promising technologically. Six such technologies are briefly addressed in Appendix A.
Download or read book Design of Remediation Systems written by Jimmy H. C. Wong and published by CRC Press. This book was released on 2020-08-18 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: While numerous books are available on remediation systems, this is the first work to document and explain in full the design aspects of the subject. Based on sound engineering principles and practical construction considerations, this text explains the entire process of remediation design, from assessment to completion, and provides engineers with the tools they need to conduct a pilot test, apply the results, and design a practical, efficient system. Design of Remediation Systems first establishes the underlying principles behind each technology, then outlines the standard procedures for designing a system. This comprehensive manual explains feasibility and pilot tests, data evaluation, design considerations and parameters, calculations and equations, and construction aspects of the system. Also featured are discussions of the operation and maintenance of systems, and analysis of current trends, such as combining soil vapor extraction with air sparging. Detailed case study examples are included in each chapter. The book considers petroleum hydrocarbons as the primary contaminant, but the principles and procedures can be applied to a wide range of other contaminants. This hands-on text/reference presents a complete picture of remediation system design for engineers, students, and scientists. No other single work offers the thorough coverage of this critical aspect of remediation.

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.
