Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at developing methodologies for optimal monitoring of groundwater contamination. The detection and remediation of groundwater contamination involves monitoring of the contaminant plume in groundwater systems. Design of optimal monitoring network remains a challenging task due to various associated uncertainties and budgetary limitations. A simulation-optimization based algorithm is presented here. A geostatistical based Kriging algorithm is used and then linked with Simulated Annealing (SA) as optimization tool. Two broad scenarios are considered, when the groundwater contaminant source characteristics (location, magnitude and direction) are known and when it is not possible to identify the actual source characteristics. This book also presents SA based methodology using feedback information on concentration measurements at designed monitoring locations for sequential characterization of contaminant plume. An example study area located in a district of the Indian state is chosen for testing the performance of the developed methodologies. This book will serve the need of the postgraduate students for doing research work in the area of groundwater.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Design of Water Quality Monitoring Systems Design of Water Quality Monitoring Systems presents a state-of-the-art approach to designing a water quality monitoring system that gets consistently valid results. It seeks to provide a strong scientific basis for monitoring that will enable readers to establish cost-effective environmental programs. The book begins by reviewing the evolution of water quality monitoring as an information system, and then defines water quality monitoring as a system, following the flow of information through six major components: sample collection, laboratory analysis, data handling, data analysis, reporting, and information utilization. The importance of statistics in obtaining useful information is discussed next, followed by the presentation of an overall approach to designing a total water quality information system. This sets the stage for a thorough examination of the quantification of information expectations, data analysis, network design, and the writing of the final design report. Several case studies describe the efforts of various organizations and individuals to design water quality monitoring systems using many of the concepts discussed here. A helpful summary and final system design checklist are also provided. Design of Water Quality Monitoring Systems will be an essential working tool for a broad range of managers, environmental scientists, chemists, toxicologists, regulators, and public officials involved in monitoring water quality. The volume will also be of great interest to professionals in government, industry, and academia concerned with establishing sound environmental programs.

This book was released on 2013-03-09 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the adequacy of collected water quality data and the performance of existing monitoring networks have been seriously evaluated for two basic reasons. First, an efficient information system is required to satisfy the needs of water quality management plans and to aid in the decision-making process. Second, this system has to be realized under the constraints of limited financial resources, sampling and analysis facilities, and manpower. Problems observed in available data and shortcomings of current networks have led researchers to focus more critically on the design procedures used. The book is intended to present an up-to-date overview of the current network design procedures and develop basic guidelines to be followed in both the design and the redesign of water quality monitoring networks. The book treats the network design problem in a comprehensive and systematic framework, starting with objectives of monitoring and elaborating on various technical design features, e.g. selection of sampling sites, sampling frequencies, variables to be monitored, and sampling duration. The design procedures presented are those that the authors have recently applied in a number of national and international projects on the design and redesign of water quality monitoring networks. Thus, the book covers real case studies where not only the methods described in the earlier titles are used but also new techniques are introduced. Where earlier methods are used, they are assessed with respect to their efficiency and applicability to real case problems. Audience: Essentially, the framework adopted in the book applies as well to other hydrometric data collection networks besides those of water quality. In this respect, it is expected that planners, designers, scientists, and engineers who are involved in hydrometric network design will benefit from the in-depth approach assumed in this book. It will also be of interest to research and data centers, international programs and organizations related to environmental monitoring. The book may also be used as a reference text in graduate courses of water resources and environmental engineering programs.

Fisher and published by CreateSpace. This book was released on 2013 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term groundwater monitoring networks can provide essential information for the planning and management of water resources. Budget constraints in water resource management agencies often mean a reduction in the number of observation wells included in a monitoring network. A network design tool, distributed as an R package, was developed to determine which wells to exclude from a monitoring network because they add little or no beneficial information. A kriging-based genetic algorithm method was used to optimize the monitoring network. The algorithm was used to find the set of wells whose removal leads to the smallest increase in the weighted sum of the (1) mean standard error at all nodes in the kriging grid where the water table is estimated, (2) root-mean-squared-error between the measured and estimated water-level elevation at the removed sites, (3) mean standard deviation of measurements across time at the removed sites, and (4) mean measurement error of wells in the reduced network. The solution to the optimization problem (the best wells to retain in the monitoring network) depends on the total number of wells removed; this number is a management decision. The network design tool was applied to optimize two observation well networks monitoring the water table of the eastern Snake River Plain aquifer, Idaho; these networks include the 2008 Federal-State Cooperative water-level monitoring network (Co-op network) with 166 observation wells, and the 2008 U.S. Geological Survey-Idaho National Laboratory water-level monitoring network (USGS-INL network) with 171 wells. Each water-level monitoring network was optimized five times: by removing (1) 10, (2) 20, (3) 40, (4) 60, and (5) 80 observation wells from the original network. An examination of the trade-offs associated with changes in the number of wells to remove indicates that 20 wells can be removed from the Co-op network with a relatively small degradation of the estimated water table map, and 40 wells can be removed from the USGS-INL network before the water table map degradation accelerates. The optimal network designs indicate the robustness of the network design tool. Observation wells were removed from high well-density areas of the network while retaining the spatial pattern of the existing water-table map.
