Dense Chlorinated Solvents & Other DNAPLs in Groundwater History, Behavior, and Remediation

Edited by James F. Pankow and John A. Cherry

The acclaimed and authoritative reference book on the history, movement, and remediation of chlorinated solvents in groundwater was written by North America's top professionals. The reference includes 15 Chapters (525 pages), with numerous illustrations.

The book was sponsored by the University Consortium Solvents-in-Groundwater Research Program and Published by Waterloo Press. It is now out of print. We are working on a plan to distribute the book in electronic form. Please check back for an update on this.

Every once in a while a publication comes along that is so timely, on-target, well-written, and well-illustrated that it makes a complex and misunderstood subject crystal-clear. Dense Chlorinated Solvents, a 522-page hardcover book edited by Professors James F. Pankow of the OGI School of Science & Engineering and John A. Cherry of the University of Waterloo, Ontario, is such a book. It is based on research carried out by the University Consortium Solvents-in-Groundwater Research Program. Principal research institutions participating in the industry-sponsored consortium include the University of Waterloo and Queen's University in Canada, and the OGI School of Science & Engineering and Colorado State University in the U.S. The book has excellent background/over-view chapters that summarize current knowledge, detailed papers that back up the syntheses, and a few illustrative case histories.

The book contains 14 chapters. Chapter 1 is a comprehensive 52-page introduction that gives the background and history of the DNAPL (dense, nonaqueous phase liquid) and dissolved plume problem. It includes a summary discussion of the properties of dense chlorinated solvents as related to their occurrence in the vadose and saturated zones. The chapter documents early ASTM and chem›cal company MSDSs recommending land disposal of chlorinated solvents.

Chapter 2, Conceptual Models for the Behavior of DNAPLs in the Subsurface (36 pages), discusses the occurrence of these contaminants in the vadose zone and in the saturated zone and in dissolved plumes. Physical and chemical principles are covered, and implications for site characterization, monitoring, and remediation are discussed. Occurrence below the water table is broken up into porous media, fractured, and layered systems.

Detailed technical papers include: Mechanisms and mathematics of the movement of DNAPLs (31 pages); Numerical simulation (16 pages); Experimental studies of movement of DNAPLs (34 pages); Vapor migration in the vadose zone (23 pages); Dissolution of DNAPLs in the subsurface (30 pages); Sorption to aquifer materials (34 pages); Chemical and microbiological transformations and degradation of chlorinated solvents (43 pages); The effects of chlorinated solvents on the permeability of clays (24 pages); Physics governing the migration of DNAPLs in fractured media (18 pages); and Molecular diffusion in fractures (40 pages).

Chapter 13, Diagnosis and Assessment of DNAPL Sites (80 pages) addresses the problem of finding DNAPLs in the source area. Types of DNAPL chemicals are reviewed, followed by a discussion of DNAPL penetration into the subsurface. A discussion on determining the presence of DNAPLs based on intrusive and nonintrusive field work is presented, followed by a section on chemical analysis of soil and rock. Dissolved plumes are discussed in a section that includes a New Jersey case history of plume regeneration after pump and treat.

The final chapter deals with concepts for remediation of sites contaminated with DNAPLs, and is followed by an appendix containing tables of physical and chemical properties.

Dense Chlorinated Solvents and Other DNAPLs in Groundwater (l996), edited by James F. Pankow and John A. Cherry, documents why TCE, PCE, TCA, and DCM will be around to haunt us for decades, if not centuries. This is a state-of-the-art reference book that should be read by everybody in the industry working in the investigation and remediation of DNAPLs and their dissolved plumes. The book is available for U.S. $95.00 (CDN $125.00) plus shipping and handling, from Waterloo Educational Services Inc., 143 Dennis Street, Rockwood, Ontario NOB 2KO tel: 519-856-9119. fax: 519-856-0759.
