Groundwater Quality Protection


Book Description

Groundwater is an essential natural resource for the economic and secure provision of drinking water supplies. Pollution hazard assessment is an essential part of environmental best practice for water supply utilities, both in terms of protecting groundwater quality from future pollution and mitigating threats posed by existing activities. This book looks at the need for groundwater protection strategies, and provides a technical guide to methodological approaches including: mapping aquifer pollution vulnerability; the delineation of groundwater supply protection areas; developing an inventory of subsurface contaminant load; and the assessment and control of groundwater pollution hazards. The guide is particularly relevant for the Latin American and Caribbean region where many cities are highly dependent upon groundwater resources.




Groundwater Quality Sustainability


Book Description

Sustainable groundwater development requires knowledge of the appropriate recharge and transport-processes. This is a prerequisite to understanding: (i) groundwater resources and their availability, and (ii) the dependence between groundwater and the environment. Conceptual understanding of groundwater flow at both temporal and spatial scales (local and regional) is essential for management that will support engineering, industry, agriculture, ecology, and all environmentally related issues. This book has been prepared for scientists, researchers, students, engineers, water resources specialists, groundwater consultants, government administrators and teachers. It is of direct and applied interest to practitioners in hydrogeology and groundwater (resources, quality, pollution, protection and clean-up), geochemistry and hydrogeochemical modelling, and investigators into environmental hydrology, groundwater dependent ecosystems, and other practical environmental issues.




Plans and Practices for Groundwater Protection at the Los Alamos National Laboratory


Book Description

The world's first nuclear bomb was a developed in 1954 at a site near the town of Los Alamos, New Mexico. Designated as the Los Alamos National Laboratory (LANL) in 1981, the 40-square-mile site is today operated by Log Alamos National Security LLC under contract to the National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE). Like other sites in the nation's nuclear weapons complex, the LANL site harbors a legacy of radioactive waste and environmental contamination. Radioactive materials and chemical contaminants have been detected in some portions of the groundwater beneath the site. Under authority of the U.S. Environmental Protection Agency, the State of New Mexico regulates protection of its water resources through the New Mexico Environment Department (NMED). In 1995 NMED found LANL's groundwater monitoring program to be inadequate. Consequently LANL conducted a detailed workplan to characterize the site's hydrogeology in order to develop an effective monitoring program. The study described in Plans and Practices for Groundwater Protection at the Los Alamos National Laboratory: Final Report was initially requested by NNSA, which turned to the National Academies for technical advice and recommendations regarding several aspects of LANL's groundwater protection program. The DOE Office of Environmental Management funded the study. The study came approximately at the juncture between completion of LANL's hydrogeologic workplan and initial development of a sitewide monitoring plan.




Valuing Ground Water


Book Description

Because water in the United State has not been traded in markets, there is no meaningful estimate of what it would cost if it were traded. But failing to establish ground water's valueâ€"for in situ uses such as sustaining wetlands as well as for extractive uses such as agricultureâ€"will lead to continued overuse and degradation of the nation's aquifers. In Valuing Ground Water an interdisciplinary committee integrates the latest economic, legal, and physical knowledge about ground water and methods for valuing this resource, making it comprehensible to decision-makers involved in Superfund cleanup efforts, local wellhead protection programs, water allocation, and other water-related management issues. Using the concept of total economic value, this volume provides a framework for calculating the economic value of ground water and evaluating tradeoffs between competing uses of it. Included are seven case studies where ground-water valuation has been or could be used in decisionmaking. The committee examines trends in ground-water management, factors that contribute to its value, and issues surrounding ground-water allocation and legal rights to its use. The book discusses economic valuation of natural resources and reviews several valuation methods. Presenting conclusions, recommendations, and research priorities, Valuing Ground Water will be of interest to those concerned about ground-water issues: policymakers, regulators, economists, attorneys, researchers, resource managers, and environmental advocates.




Groundwater Quality Protection Practices


Book Description

Reviews the applicability of groundwater protection practices developed within other jurisdictions to the Fraser River basin. Begins with background information on groundwater sources within the four regions of the basin and discussion of the common sources of groundwater contamination, including sources designed to discharge or store substances, transport or transmission sources, sources discharging substances as a consequence of other activities, and naturally occurring sources affected by human activity. Groundwater protection measures (non-regulatory and/or regulatory) are the reviewed, and the final chapter outlines the steps involved in the development of a municipal groundwater quality protection plan. Protection measures include monitoring, waste collection, land acquisition, sewage control, forest management, zoning, design and operation controls, and inspection/compliance measures. Appendices include a detailed evaluation of nine selected groundwater protection plans that have been implemented at a municipal level.




Ground Water Vulnerability Assessment


Book Description

Since the need to protect ground water from pollution was recognized, researchers have made progress in understanding the vulnerability of ground water to contamination. Yet, there are substantial uncertainties in the vulnerability assessment methods now available. With a wealth of detailed information and practical advice, this volume will help decision-makers derive the most benefit from available assessment techniques. It offers: Three laws of ground water vulnerability. Six case studies of vulnerability assessment. Guidance for selecting vulnerability assessments and using the results. Reviews of the strengths and limitations of assessment methods. Information on available data bases, primarily at the federal level. This book will be indispensable to policymakers and resource managers, environmental professionals, researchers, faculty, and students involved in ground water issues, as well as investigators developing new assessment methods.




Ground Water Quality Protection


Book Description

Using regional case studies, this document examines representative programs for dealing with ground water contamination. Section one describes the ground water protection strategy of the U.S. Environmental Protection Agency (EPA); (2) discusses the limited data available for determining the extent of contamination; (3) provides a listing of the states selected for review in this study; and (4) suggests some criteria for effective ground water programs. Section two summarizes the conclusions and recommendations of the study, along with some general findings. Section three provides summaries of the 11 state and local ground water programs that were reviewed. The final section contains state and local strategies to protect ground water, and discusses information collection and management systems, classification systems, ground water quality standards, control of contamination sources, and the implementation of ground water protection programs. Legal information, references, a bibliography, and a list of state and local officials involved in ground water protection is included. (TW)







Groundwater Quality


Book Description

Groundwater quality monitoring and testing is of paramount importance both in the developed and developing world. This book presents a series of papers illustrating the varied nature of current research into groundwater quality. Urban and rural supplies are covered through a case history approach, and the importance of remedial action to prevent deterioration is emphasized.
