Synopses & Reviews
Groundwater treatment is unique. Removing the sources of contamination, as we did when we cleaned a river or lake, is only the first step. A groundwater remediation must include cleaning of the body of water itself, the aquifer. The revised and updated edition of Groundwater Treatment Technology provides a complete review of the technologies developed over the past 10 years for groundwater treatment. It also explains the design techniques that are required to apply those technologies successfully in a groundwater cleanup. Featured areas of coverage include:
- Specific design methods for the various technologies that are merely described in other publications
- Physical/chemical and treatability properties of 30 organic compounds that are most often encountered in groundwater situations
- Detailed strategies for remediation
- New biological treatment methods
- Specific data on treatment methods as applied in the field
- Practical suggestions on applications of technologies for groundwater treatment
Drawing on his experience as a designer of over 100 groundwater treatment systems, Evan K. Nyer starts by showing how to develop the data necessary to define what type of treatment is necessary. He then explains how groundwater treatment is unique. Nyer follows with expert accounts of specific treatment technologies. Physical/chemical organic methods such as air stripping, carbon adsorption, and pure compound removal are explored in detail. In addition, new techniques including UV Oxidation and other emerging technologies are explained and directly related to groundwater design situations. An entire chapter is devoted to biological methods, one of the most promising areas for organic groundwater treatment. There is also comprehensive coverage of inorganic methods, that addresses everything from precipitation to solids/liquid separation and advanced ion removal methods. This definitive sourcebook also contains helpful cost factor analyses, plus representative case histories showing how the techniques of groundwater treatment have been applied in the field. Wide-ranging, authoritative, and completely updated, the Second Edition of Groundwater Treatment Technology is essential reading for wastewater engineers, industrial managers, hydrologists, soil experts, government officials, and environmental lawyers who want to keep abreast of the latest developments in this important field.
Synopsis
Groundwater Treatment Technology has been the leading text on above ground groundwater remediation technologies for the past twenty years. With a unique focus on above-ground treatment technologies, this Third Edition discusses new chemical analysis methods and regulations covering arsenis, radon, 1,4 dioxane, MTBE, Perchlorae, and NDMA amongst others. Other new material includes information on the regulation and design of drinking water systems; specific data on treatment methods as applied in the field; detailed strategies for remediation; and an explanation of design philosophy that gives the reader a clear understanding of the design process and the goals to be met.
Synopsis
'a key resource on groundwater remediation, thoroughly updated and revised
The cleanup of groundwater is unique. Unlike every other type of water, groundwater is not self-cleaning; we must clean the body of water, the aquifer, itself. Evan Nyer\'s Groundwater Treatment Technology has been the key to understanding the treatment of groundwater contamination for professionals in environmental engineering and treatment systems. Adapting to recent developments in technology, regulations, and approaches for mitigating newly monitored contaminants, this Third Edition updates and extends its coverage, this time with a dedicated focus on aboveground treatment.
Groundwater Treatment Technology, Third Edition provides a complete review of current technologies for groundwater treatment. It also explains the design techniques that are required to apply those technologies successfully in a groundwater cleanup and provides the reader with the unique design criteria and detailed knowledge of these specific treatment methods. Given the current prominence of aboveground treatment, the text limits the design discussion to aboveground techniques, though it still discusses how the various aboveground technologies interact with various in-situ methods.
New to the Third Edition:
- A unique focus on aboveground treatment technologies
Coverage of new treatment methods and regulations for arsenic, radon, 1,4-dioxane, MTBE, perchlorate, and NDMA among others
New material covering the operations of treatment systems
Detailed strategies for remediation
Specific data on treatment methods as applied in the field
Wide-ranging, authoritative, and completely updated, the Third Edition of Groundwater Treatment Technology is essential reading for wastewater engineers, industrial managers, hydrologists, soil experts, government officials, and environmental lawyers who want to keep abreast of the latest developments in this still challenging field.
