1,4-dioxane contamination of groundwater is widespread. Why has it been overlooked at so many solvent release sites and landfills?

This question compelled the author to pursue years of research and inquiry on 1,4-dioxane that culminated in the compilation of this comprehensive reference volume. The book covers all the solvent stabilizers added to the major chlorinated solvents, and examines their environmental fate and transport characteristics. The uses and occurrence of 1,4-dioxane are listed for the complete range of industrial applications, including 1,4-dioxane as a by-product. 1,4-Dioxane contaminant transport properties including vapor phase transport and solute transport, adsorption, matrix diffusion and back-diffusion, and biodegradation are profiled in the extensive fate and transport chapter. The hydrophilic nature of 1,4-dioxane creates challenges for laboratory analysis. The full gamut of available laboratory methods are described and contrasted, and passive approaches for 1,4-dioxane sampling are compared. One of USA’s top authorities on 1,4-dioxane toxicology, Dr. Julie Stickney of Syracuse Research Corporation, prepared the toxicology chapter. The wide range of state approaches to regulating 1,4-dioxane is described in a chapter on risk and regulation, which includes NPDES requirements and aquatic toxicity summaries. The expertise of an experienced practitioner of 1,4-dioxane treatment, William DiGuiseppi of AECOM, was enlisted to write the treatment chapter. The treatment chapter provides an invaluable resource to both consultants and regulators faced with selecting the most effective and economical treatment technology. The treatment chapter is complemented by a chapter featuring seven 1,4-dioxane case studies profiling modes of release, migration patterns, site characterization efforts, regulatory response, community outreach, and legal cases. A chapter on forensic investigation methods explains how solvent stabilizers can be leveraged to augment other forensic methods for determining the age of a release and deconvoluting comingled plumes, and examines the prospects for using CSIA to confirm 1,4-dioxane biodegradation for monitored natural attenuation. A tenth chapter features a wide-ranging examination of the regulatory policy implications of “emerging” contaminants such as 1,4-dioxane. Three appendices supply an extended list of solvent stabilizer fate and transport properties, a summary of published laboratory analysis approaches, and a synopsis of important solvent stabilization patents.
