This report provides best practice guidance of borehole monitoring, maintenance, rehabilitation and design and construction to optimise water supply from groundwater sources.
Throughout the world, boreholes and tubewells operate inefficiently or have been abandoned. Diagnosis of the problems requires hydrogeological and operational information, which is often not available because appropriate monitoring has not taken place. Guidelines on cost effective monitoring and maintenance need to be established; information on successful rehabilitation techniques is needed. This book forms the proceedings of a conference organised to exchange practical experience and scientific knowledge on these aspects of water wells.
There is a growing problem of performance degradation of wells and associated systems on sites where groundwater quality is monitored or remediation performed. This book acts as a valuable guide in keeping monitoring and pumping well systems operating to their best capacity. It addresses the need for and methods of environmental well maintenance and restoration. This guidebook to the causes of well deterioration, methods of well maintenance, and well restoration or well rehabilitation methods offers methods for prevention and control of deterioration. If you are a consumer of professional services in well rehabilitation, this book will help you get the most from your professional help. It you are a provider, it is an important source of information intended to help you do your job better and more safely.
Water Wells and Boreholes provides the necessary scientificbackground together with practical advice using global casestudies, in an accessible easy to use style suitable for bothpostgraduates/researchers and practitioners. The book begins with an introduction to the type and uses ofwater wells from water supply and irrigation through to groundwaterremediation. It then covers well siting detailing how to sourcedata from geophysical surveys, remote sensing etc. Well design isthen summarised to ensure the well is stable and cost-effective.The book ends with three chapters covering well construction, welltesting and well performance, maintenance and rehabilitation.
Water has become one of the most important issues of our time intertwined with global warming and population expansion. The management of water supplies and the conservation of water resources remains one of the most challenging yet exciting issues of our time. Water and wastewater treatment technologies are constantly evolving creating an increasingly sustainable industry that is one of the world's largest and most interdisciplinary sectors, employing chemists, microbiologists, botanists, zoologists as well as engineers, computer specialists and a range of different management professionals. This accessible student textbook introduces the reader to the key concepts of water science and technology by explaining the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management. This fourth edition is extensively changed throughout, with new coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity. The text serves as a primer for both undergraduate and graduate students in either science or engineering who have an interested in freshwater biology/hydrobiology or environmental engineering. It is also useful as a unified transitional course for those who want to span the traditional areas of engineering, biology, chemistry, microbiology or business. Professionals and consultants will also find the book a useful reference.
Groundwater Lowering in Construction outlines the practical aspects of groundwater lowering which are of assistance for the successful and economical completion of construction projects. This book is the definitive reference for the practising engineer, engineering geologist, and advanced civil engineering or engineering geology student dealing with below ground excavations and constructions.
Twort's Water Supply, Seventh Edition, has been expanded to provide the latest tools and techniques to meet engineering challenges over dwindling natural resources. Approximately 1.1 billion people in rural and peri-urban communities of developing countries do not have access to safe drinking water. The mortality from diarrhea-related diseases amounts to 2.2 million people each year from the consumption of unsafe water. This update reflects the latest WHO, European, UK, and US standards, including the European Water Framework Directive. The book also includes an expansion of waste and sludge disposal, including energy and sustainability, and new chapters on intakes, chemical storage, handling, and sampling. Written for both professionals and students, this book is essential reading for anyone working in water engineering. - Features expanded coverage of waste and sludge disposal to include energy use and sustainability - Includes a new chapter on intakes - Includes a new chapter on chemical storage and handling
Effective management of a water well requires that the water well can meet a set of performance indicators. These can include criteria related to water quality, yield, economics and asset life. Water well deterioration due to fouling and corrosion impacts the ability of a well system to meet these criteria. Managing well deterioration processes involves understanding the nature of these processes and having in place water well maintenance strategies to deal with them. Managing water well deterioration fills a need within the literature for an academically based informative text that incorporates practical advice. The focus on a problem-oriented approach to diagnosing well deterioration makes the book a useful practical handbook. It integrates concepts from hydrogeology, hydrochemistry and microbiology to give a thorough understanding of water well deterioration processes. Scenarios have been developed to illustrate common causes of water well fouling. A feature of the book is the treatment of both corrossion and fouling issues in depth. Case studies selected from around the world are uses to illustrate approaches to the diagnosis and remediation of well deterioration. These scientifically orientated perspectives on water well deterioration are embedded within a management framework to provide a comprehensive approach to dealing with water well deterioration.
Water Wells and Boreholes focuses on wells that are used for drinking, industry, agriculture or other supply purposes. Other types of wells and boreholes are also covered, including boreholes for monitoring groundwater level and groundwater quality. This fully revised second edition updates and expands the content of the original book whilst maintaining its practical emphasis. The book follows a life-cycle approach to water wells, from identifying a suitable well site through to successful implementation, operation and maintenance of the well, to its eventual decommissioning. Completely revised and updated throughout, Water Wells and Boreholes, Second edition, is the ideal reference for final-year undergraduate students in geology and civil engineering; graduate students in hydrogeology, civil engineering and environmental sciences; research students who use well data in their research; professionals in hydrogeology, water engineering, environmental engineering and geotechnical engineering; and aid workers and others involved in well projects.
Part of Groundwater Set - Buy all six books and save over 30% on buying separately! Groundwater serves many purposes. It is a source of public and private drinking water, it is utilized as an industrial feedstock and it is used in agriculture for irrigation and cattle watering. The abstraction of groundwater also serves many civil engineering purposes such as structures, construction pit dewatering and remediation of polluted groundwater. Furthermore, groundwater is increasingly used for supply and storage of energy for the cooling and heating of buildings. Many wells abstracting groundwater suffer from impaired performance as a result of clogging by mechanical or biogeochemical processes. This represents a significant economic loss due to volume reductions, cost of well rehabilitations or construction of new wells. Cause and Prevention of Clogging of Wells Abstracting Groundwater from Unconsolidated Aquifers provides a comprehensive description of the various causes and processes associated with well clogging in addition to describing methodologies for diagnosis and prevention.
