Description

A ubiquitous, largely overlooked groundwater contaminant, 1,4-dioxane escaped notice by almost everyone until the late 1990s. While some dismissed 1,4-dioxane because it was not regulated, others were concerned and required testing and remediation at sites they oversaw. Drawing years of 1,4-dioxane research into a convenient resource, Environmental Investigation and Remediation: 1,4-Dioxane and other Solvent Stabilizers profiles the nature of 1,4-dioxane and several dozen other solvent stabilizer compounds.


The author takes an approach he calls "contaminant archeology", i.e., reviewing the history of the contaminating chemical's use in the industrial workplace at the site of release and how those uses impart chemical characteristics to the waste that affects its fate and transport properties. The book examines the uses, environmental fate, laboratory analysis, toxicology, risk assessment, and treatment of 1,4-dioxane in extensive detail. It provides case studies that document the contaminant migration, regulation, treatment, and legal aspects of 1,4-dioxane releases. It also describes the controversy over interpretation of 1,4-dioxane's toxicology and associated risk, as well as the corresponding disparity in states' regulation of 1,4-dioxane. A final chapter examines the policy implications of emerging contaminants like 1,4-dioxane, with discussion of opportunities to improve the regulatory and remedial response to this persistent contaminant in the face of toxicological uncertainty.


Mobility, persistence, and treatment challenges combine to make 1,4-dioxane a particularly vexing contaminant. It is more mobile than any other contaminant you are likely to find at solvent release sites. Filled with case studies, equations, tables, figures, and citations, the book supplies a wide range of information on 1,4-dioxane. It then provides passive and active remediation strategies and treatment technologies for 1,4-dioxane in groundwater and provides you with the technical resources to help you decide which are appropriate for your site.

Review quote

"Tom Mohr's book on 1,4-Dioxane and Other Solvent Stabilizers is the most thorough and practical treatise on the subject - an amazingly complete book. It's an especially must-read for anyone dealing with the chlorinated solvent 1,1,1-TCA because even today many professionals in the field do not test for 1,4-Dioxane when it is highly likely to be present if 1,1,1-TCA is a contaminant of concern."
-Dr. Robert W. Cleary, Instructor, The Princeton Groundwater Courses, Tampa, Florida

"Tom Mohr has done the environmental profession a great service by publishing in 2010 the most comprehensive summary of a significant contaminant in the groundwater environment, 1,4-dioxane. Chlorinated solvents represent the most significant legacy contaminants at groundwater sites in the U.S. and probably worldwide and the potential impact of solvent stabilizers has only relatively recently been appreciated given the mobility of 1,4-dioxane in groundwater and the challenges removing the chemical from water. Mohr's extremely well documented book on the history, fate, transport, treatment, remediation and regulatory status of this contaminant is of great value to all involved in the on-going challenges to restore groundwater to its highest beneficial use."
-Dr. Michael Kavanaugh, P.E., Geosyntec Consultants, Oakland, California, Member, National Academy of Engineering, Chair, National Research Council Committee on Future Options for the Nation's Subsurface Remediation Effort

"You won't find the 1,4-dioxane book on my reference shelves - I keep it on my desk."
-Dr. Stanley Feenstra, Applied Groundwater Research Ltd., Missisauga, Ontario, Canada, Co-author of Dense Non-Aqueous Phase Liquids

"I received your book last week and have read it cover to cover twice since then - it's a great product and one that significantly advances the knowledge on chlorinated solvents/stabilizers. It has incredible information and is well-written and well-referenced. It is rare that a book like this comes along. The chapters on stabilizers and the extraction of information from the U.S. patent literature throughout the chapters provide valuable insights."
-Dr. Robert D. Morrison, DPRA, Hawi, Hawai'I, Author of Environmental Forensics - Principles and Applications, and Environmental Forensics - the Contaminant Specific Guide

"This authoritative book embodies a great deal of information on 1,4 dioxane in a useful manner. The authors in their personal style of writing call it "MTBE on steroids"; they take a potentially encyclopedic and boring topic and make it a fun to read yet admirably educating book. This very soluble and mobile chemical is a big concern in so many places around the world. I believe this book is of great importance to anyone involved in the elimination of exposure to 1,4 dioxane. The book is arranged methodologically and encompasses information from the history of of 1,4 dioxane uses to the most recent remedial techniques. This text is mainly for professionals and managers working with 1,4 dioxane remediation but will also serve well the general public, especially those who are in an actual exposure scenario to 1,4 dioxane."
