Ground Water Models
The discovery of toxic pollution at Love Canal brought ground water contamination to the forefront of public attention. Since then, ground water science and modeling have become increasingly important in evaluating contamination, setting regulations, and resolving liability issues in court. A clearly written explanation of ground water processes and modeling, Ground Water Models focuses on the practical aspects of model application. It: examines the role of models in regulation, litigation, and policy development; explains ground water processes and describes specific applications for models; presents emerging technologies; and offers specific recommendations for better use of ground water science in policy formation.

Groundwater Recharge and Flow
Water of appropriate quantity and quality is essential for drinking, sanitation, and food, energy, and industrial production for any society and is derived for most needs from surface- or groundwater sources. Studies suggest that groundwater use in irrigation globally is increasing in total volume as well as a percentage of all water used for irrigation, with the demand for groundwater resources increasing as available primary surface water supplies are depleted. Particularly in arid regions, groundwater may be the most accessible water supply for any purpose, leaving groundwater withdrawals concentrated in areas that are already experiencing water stress. Even in the presence of direct grou...
Ground Water Vulnerability Assessment
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.
Groundwater Modeling and Management under Uncertainty
Groundwater is a vital resource of water, in some regions of the world the only source of fresh water. Its use for domestic use and agriculture dates back thousands of years. In recent decades the over-exploitation and unabated use of this resource has lead to severe environmental problems such as resource depletion, land subsidence and groundwater contamination. To mitigate these adverse impacts and protect this valuable resource, it is imperative that rational groundwater management practices and policies as well as robust modeling and analysis tools be developed. This volume and the accompanying USB memory card include the abstracts and full papers that were presented at the 6th Internati...
Quality of Ground Water
Three sets of model classification criteria are shown to be useful including: intended usage for prediction, exploration of management questions, or identification and characterization of parameters; function or capability to simulate flow, mass transport, or heat energy transport: and conceptual basis for representing ground water systems, along with how governing equations are set up and solved.
Groundwater Assessment and Modelling
Groundwater development has shown phenomenal progress during past few decades. There has been a vast improvement in the perception, outlook and significance of groundwater resource. The unplanned groundwater development may result in fall of water levels, failure of wells, and salinity ingress in coastal areas. The development and over-exploitation of groundwater resources in many parts of the world have raised the concern and need for judicious and scientific resource management and conservation. This book "Groundwater Assessment and Modelling" is intended to provide a comprehensive treatise on assessment and modelling of groundwater. It presents the related aspects on assessment of groundw...
Groundwater Monitoring
Groundwater is sometimes called “the hidden asset” – awareness of its existence and its importance is not well known and as a consequence the measures which are required to protect and manage it in an environmental sustainable way are either not taken or are taken too late. Where pollution has occurred and measures are taken too late it may take decades, or longer, until the necessary restoration of quality is achieved. This comprehensive text presents in the following sections: Groundwater monitoring in the regulatory and international context Conceptual modelling and network design Groundwater pollutants and other pressures Groundwater quality standards and trend assessment Case studies for groundwater assessment and monitoring in the light of EU legislation Groundwater measurements Associating external stakeholders The editors have collected state-of-the-art information on groundwater quality assessment monitoring from the international community, providing further stimulation to the work of all parties involved in the challenges this area creates to ensure sound quality assessment of groundwater.
Risk Assessment for Groundwater Pollution Control
Prepared by the Groundwater Risk Assessment Task Committee for the Water Pollution Management Committee of the Environmental Engineering Division of ASCE. ThisØreport discusses the control of contaminated groundwater and the use of risk assessment to mitigate this contamination. The report explores such issues asØdefining the level of contamination,Ødetermining which substances are contaminants, andØdeciding the level of restoration needed. These and other issues are discussed within the framework of risk assessment and risk management. Critical components of risk assessment and risk management are described, as are their strengths and weaknesses.
