Advanced Groundwater Remediation

This book presents a concise summary of advanced groundwater treatment methods, especially 'pump-and-treat' and 'permeable reactive barriers'. The topics include heavy metal removal, with special emphasis on uranium, and sorption, one of the basic mechanisms in groundwater remediation.

This volume has been organized for practicing engineers who deal with the problems of groundwater and leachate remediation. It is intended to provide a practical overview of both techniques for evaluating groundwater quality and in selecting remediation technologies that are cost effective. Emphasis is given to advanced remediation methods.

The book presents the results of the University of Waterloo's project to test permeable, reactive barriers with the goal of finding the best in situ method for groundwater remediation. This project advanced the demonstration of reactive barriers by testing combinations in sequence.

Advances in Remediation Techniques for Polluted Soils and Groundwater focuses on the thematic areas for assessment, mitigation, and management of polluted sites. This book covers advances in modelling approaches, including Machine Learning (ML)/ Artificial Intelligence (AI) applications; GIS and remote sensing; sensors; impacts of climate change on geogenic contaminants; and socio-economic impacts in the poor rural and urban areas, which are lacking in a more comprehensive manner in the previous titles. This book encompasses updated information as well as future directions for researchers working in the field of management and remediation of polluted sites. Introduces fate and transport of multi-pollutants under varying subsurface conditions Details underlying mechanisms of biodegradation and biodetoxification of geogenic, industrial and emerging pollutants Presents recent advances and challenges in assessment, water quality modeling, uncertainty, and water supply management Provides authoritative contributions on the diverse aspects of management and remediation from leading experts around the world

In recent years the analysis, control, preservation, remediation and correct management of underground resources have received a growing attention in a variety of sectors, including industrial, professional and academic environments. The volume describes new developments in both applied research and design technology to maintain sustainability of a vital resource (groundwater) which is continuously threatened by contamination resulting from solid waste disposal operations, site reutilization, intensive extraction, accidental leakage of spill in working installations and non-point source pollution in agriculture. It is directed to managers, professionals, and researchers working in any of the areas concerned with the control, prediction, and remediation of soil and groundwater contamination.

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.

Groundwater is one of the Earth’s most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, industry, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.
