E-grāmata: Innovative Approaches to the On-Site Assessment and Remediation of Contaminated Sites

Presents seven multi-authored contributions addressing in situ and onsite management of contaminated sites. Topics addressed are the use of a field analytical approach to accelerate site assessments; mobility and availability of contaminants; biodegradation and bioremediation; advances in phytoremediation; natural attenuation; in situ treatment technologies; and approaches to the removal of PCB from the environment. Considerable emphasis is placed on techniques to manage contaminants in situ, with attention paid to the unique transport and exposure processes associated with contaminated sediments and nonaqueous phase liquid subsurface contamination, as well as the role these processes may play in the future management of such sites. Contributions are drawn from a NATO Advance Study Institute held in Prague, Czech Republic in May 2001. Lacks a subject index. Annotation (c) Book News, Inc., Portland, OR (booknews.com)

The in-situ and on-site assessment and remediation of contaminated sites, together with risk-based management and control of hazardous substances, are potentially 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, especially in Eastern Europe and the former Soviet Union, where resources that can be devoted to chemical cleanup are especially limited.

Although much of the focus of the book is on natural processes and how they might be enhanced for the management of contaminated sites, there is also a recognition that a portion of sites may require more invasive approaches, which are especially useful in managing source areas that contribute to the migration of contaminants in groundwater and other media. Among the more invasive approaches discussed are solvent extraction, direct bioremediation of PCBs, source areas and munitions, and chemical oxidation.
