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. Bruce M. Alberts 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. William A. Wulf 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. Kenneth I. Shine 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. Bruce M. Alberts and Dr. William A. Wulf are chairman and vice chairman, respectively, of the National Research Council.
Preface
Ground water, while providing much of the nation's supplies of water for domestic, industrial, and agricultural purposes, is surprisingly underappreciated and usually undervalued. Water managers at various levels of government are faced with an array of decisions involving development, protection, and/or remediation of ground water resources. Examples of questions basic to such decisions at the local level include:
-
Should ground water be used singly or in conjunction with surface water supplies to meet increasing water usage requirements?
-
Should a comprehensive water conservation program be implemented in order to extend the availability of ground water and minimize or preclude ground water depletion?
Examples of questions basic to decisions at the state or federal level include:
-
Are the benefits of ground water protection programs greater than their costs, and how should such wellhead protection efforts be funded?
-
How should ground water remediation projects be prioritized given that the costs of remedial actions typically far exceed available funding? Should the value of ground water resources be considered in deciding if remediation efforts should be undertaken at a site?
Valuation of ground water resources is critical in determining an efficient outcome in each of these examples as well as many other ground water development, protection, and/or remediation projects, programs, or policy decisions. However, the ground water resource, a nonmarket good, is difficult to value;
and, as a result, economic valuation and future considerations have historically played almost no part in decision-making.
The fundamental need to value natural resources was recognized in a 1990 report of the Science Advisory Board (SAB) of the U.S. Environmental Protection Agency (EPA, 1990). Based on the review of comparative risk assessments of environmental problems, a committee of 39 distinguished scientists, engineers, and other experts drawn from academia, state government, industry, and public interest groups developed ten recommendations; of relevance to this report is Recommendation 10—EPA should develop improved methods to value natural resources and to account for long-term environmental effects in its economic analyses (EPA, 1990).
In 1994 the U.S. Environmental Protection Agency requested that the National Research Council (NRC) appoint a committee to study approaches to assessing the future economic value of ground water, and the economic impact of the contamination or depletion of these resources. This committee was appointed in 1994 under the auspices of the NRC's Water Science and Technology Board. The committee was charged to:
-
review and critique various approaches for estimating the future value of uncontaminated ground water in both practice and in theory;
-
identify areas in which existing approaches require further development and promising new approaches which might be developed;
-
delineate the circumstances under which various approaches would be preferred in practice for various applications of decision-making regarding long-term resource use and management;
-
outline legislative and policy considerations in connection with the use and implementation of recommended approaches, and related research needs; and
-
illustrate, through real or hypothetical case examples, how recommended procedures would be applied in practice for representative applications.
Due to the relevance of the committee charge to other public interest groups and agencies, three other sponsors provided financial support for this NRC study in addition to EPA: the National Water Research Institute, the U.S. Department of Defense, and the U.S. Department of Energy.
The focus of the study on ground water valuation and the composition of the committee established the need for economists to work with ground water experts. Disciplines represented on the committee included agricultural economics, environmental engineering, hydrogeology, microbiology, public policy, resource economics, and water law. The members were drawn from academia, private consultants, and water management positions in local government.
While the assignment was challenging, the committee quickly agreed on three matters that provided its starting points. First, an interdisciplinary approach is necessary for ground water valuation studies. Second, when valuing ground water, the in situ and ecological services must be recognized along with the more
obvious extractive services. Finally, it was recognized that common terminology was not available as a foundation for this study. Thus concepts and principles from environmental economics and ground water management had to be appropriately integrated to provide a basis for the work of the committee.
The committee has completed its task and, in so doing, has received considerable assistance from the NRC staff. Accordingly, on behalf of the committee, I wish to express our thanks to the following persons: Sheila David, Study Director; Etan Gumerman, Project Coordinator; Mary Beth Morris, Project Assistant; Ellen de Guzman, Project Assistant; Joel Darmstadter, Consultant; and Steve Parker, Director of the Water Science and Technology Board (WSTB). In addition, Henry Vaux, WSTB member and liaison to this committee, provided both helpful guidance and technical input.
Finally, I wish to express my appreciation to all committee members for their willingness to discuss new concepts from an interdisciplinary perspective, to prepare and revise materials for this report, and to strive for consensus-building on key issues. We have all learned from this process!
