Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Preface
The committee has approached this congressionally mandated task to examine the management of coalbed methane (CBM) produced water in six western states within a national context of increasing demand to develop domestic energy resources in environmentally and economically viable ways. The production of CBM for use as an energy source requires pumping water from coalbeds to release methane from the coal surfaces. The CBM “produced water” that results from this pumping process is managed through treatment, storage, disposal, and/or use, under a complex set of federal and state regulations.
Although produced water and its management are common to the majority of oil and gas production activities, CBM produced water has been the subject of specific, recent attention for several reasons: (1) the CBM industry is relatively young—with most operations in the western United States only producing methane since the 1990s—and development has been rapid in several regions; (2) the length of time to observe and understand potential effects on the environment from CBM produced water has been correspondingly brief; (3) the relatively low salinity of some CBM produced water has allowed consideration of this water for various practical uses in the arid West; and (4) litigation within and among states, citizens, and industry sharing CBM basins and watersheds has resulted from differing approaches to CBM produced water management.
To address the study, the committee reviewed documents produced by federal and state agencies and consultants, peer-reviewed literature, online databases and resources, and information requested from and submitted by external sources, including three public meetings and six public teleconferences. The committee held its public meetings in Washington, D.C.; Denver, Colorado; and Santa Fe, New Mexico. Each public meeting included dialogue with the study sponsor, the Bureau of Land Management, other federal and state agencies, academic and national laboratory researchers, and industry representatives who addressed various points of the committee’s study charge. An opportunity for public input was provided at the committee meeting in Denver.
The committee was sensitive to the interest in understanding the effects of CBM produced water on the environment when it is treated and released for disposal or might be used for any beneficial purposes. The committee was thus conscientious in its efforts to identify and distinguish between scientifically and technically documented effects of CBM produced water on the environment; those effects that may be considered “potential” effects through laboratory studies, for example, but without field documentation; and reports of effects that do not yet have enough supporting data or independent analysis to determine cause. In a comparable way, hydraulic fracturing was not a specific item the committee was tasked to address but was a topic raised to the committee’s attention during the course of this study. Hydraulic fracturing uses fluid injection to stimulate oil and gas production in many oil and gas wells but is employed rarely, or not at all, in CBM operations where coal seams are relatively near to the surface and have correspondingly high initial water contents. Without a direct link between hydraulic fracturing and the largest volumes of CBM produced water that are managed in the West, the committee addressed hydraulic fracturing only briefly in the report.
Throughout its examination of CBM produced water management, the committee has assumed that operators, regulatory agencies, water treatment companies, and private citizens alike use appropriate and professional procedures in their operations and in their management of produced water. The committee has thus focused its efforts on ways in which the current regulatory, legal, environmental, energy, and economic framework functions with respect to management of produced water from CBM operations and how this framework could be supported and improved. Nonetheless, in some instances data and information have demonstrated that “best practices” have not been followed in the management of CBM produced water and the committee has noted the situations which came to our attention.
As demands continue to couple energy resource development with environmental stewardship, demands for water resources and effective management of water for multiple uses will likewise continue to grow. In this context, an examination of CBM produced water management is timely, and the committee hopes this report informs the decision-making process with respect to important energy and water resources.

Acknowledgments
In addition to its own expertise, the committee relied on input from numerous external professionals and members of the public with extensive experience in various aspects of coalbed methane development and produced water management. All of these individuals provided presentations, data, analyses, and illustrative figures and images which assisted the committee in understanding the scope of the issue and the roles played by federal, state, and tribal governments and agencies, the private sector, non-governmental organizations, research organizations, and the public. This information was very important to the committee in formulating the report. We gratefully acknowledge these individuals, and note particularly their prompt and thorough responses to our inquiries throughout the study’s course. In particular, the committee would like to thank the following individuals: Troy Bauder, Doug Beagle, Diedre Boysen, John Boysen, Curtis Brown, David Brown, James Burd, Aïda Farag, Mark Fesmire, Don Fischer, Carol Frost, Carey Johnston, James Keener, David Mankiewicz, Vince Matthews, Elizabeth Meredith, Terrance Olson, Kevin Rein, Ashley Roberts, Kathy Shreve, Timothy Spisak, Carrie Steinhorst, David Stewart, Jason Thomas, Ralf Topper, John Veil, John Wheaton, and Michael Wireman.
This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the National Research Council’s (NRC) Report Review Committee.
