Available in PDF, EPUB and Kindle. Book excerpt: An alternative approach for characterization of sites contaminated by volatile organic compounds (VOCs) has been employed at Sandia National Laboratories, Albuquerque, New Mexico (SNL/NM), in order to characterize a plume from a chemical waste landfill (CWL). The characterization approach is designed to maximize the use of soil gas analysis for definition of the nature and extent of contamination and for validation of the conceptual model of contaminant transport. Comparison of the soil gas data analyzed at an on-site laboratory with those data generated by an EPA-approved analytical laboratory indicates that soil gas data provide a much more representative picture of site conditions. To assist in the validation of our conceptual model of contaminant transport for the CWL, we employed an approach developed at SNL/NM that allows for assessment of nonaqueous phase liquids (NAPLs) through equilibrium testing of the soil gas data.

Book excerpt: Published in 1991, the first edition of The Practical Handbook of Ground-Water Monitoring quickly became the gold standard reference on the topic of ground-water monitoring. But, as in all rapidly evolving fields, regulations change, technology advances, methods improve, and research reveals flaws in prior thinking. As a consequence, books t
Download or read book Soil Vapor Versus Discrete Soil Sample Measurements for VOCs in the Near Surface Vadose Zone Feasibility Study written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil vapor samples were taken from 1m beneath the ground surface at 16 different locations. Measured trichloroethene (TCE) in these samples was compared to that obtained for a collocated sample of the soil matrix. The linear slope (0.806) and strong correlation (r2 =0.950) obtained for this comparison of soil vapor (mg TCE/L) to soil mass (mg TCE/kg) concentrations are in good agreement with recent theoretical and empfrical models for this volatile organic compound (VOC) in a low organic carbon soil matrix. This strong relationship suggests that active soil-vapor measurements could be used as an alternative to collecting and analyzing discrete soil samples for establishing both the presence and concentration of VOCs during site characterization and monitoring. Moreover, the techniques and instruments described here are robust, simple to use, and designed to enhance the reliability of soil-gas surveys to characterize vadose zone VOC contamination.

Available in PDF, EPUB and Kindle. Book excerpt: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. Furthermore, when risk-based corrective actions are deemed necessary, the subsequent selection and implementation of the appropriate remediation technologies rely heavily upon the VOC concentrations established during site characterization activities. This report briefly addresses procedures, equipment, and logistics for the collection and timely (less than 48 hr) on-site analysis of VOCs in discrete soil and groundwater samples. The collection, preservation, and preparation procedures presented strive to acquire and maintain analyte concentrations that are representative of the location and medium from which the sample was removed.

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.

This book was released on 1997-11-21 with total page 311 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.
