Well rehabilitation techniques have been the focus of major advancements in recent times. Environmental engineers can keep pace with those changes with the book Water Well Rehabilitation. Written from a microbiological viewpoint, the text outlines proven solutions to production problems in all types of wells. That perspective frequently yields new ideas and concepts, contrary to prevalent thoughts in mainstream literature on the subject. This is especially true in discussion of iron related bacterial sources, and details concerning unsafe bacterial samples and the contamination of wells.

Capitalize on the First All-in-One Guide to Monitoring, Identifying, and Solving Problems of Ageing Water Wells Water Well Rehabilitation and Reconstruction offers water resource professionals the first comprehensive guide to the mechanical, chemical, and microbiological ageing processes of water wells. Filled with examples from Germany, the Netherlands, the United States, the United Kingdom, and Australia, this landmark reference provides the scientific background needed to understand well aging_and perform effective rehabilitation, reconstruction, and monitoring. You will find guidance on state-of-the-art testing and maintenance methods, as well as information on legal and environmental issues, such as the transport, application, and disposal of chemicals. Using SI and U.S. customary units throughout, with a handy conversion table included, Water Well Rehabilitation and Reconstruction enables you to: Identify and quantify problems affecting well performance Select rehabilitation methods appropriate for specific problems Harness methods for replacement or closure of a well if rehabilitation fails Inside This Landmark Water Well Resource • Introduction • Elements of Well Hydraulics and Well Operation • Chemical Ageing Process • Mechanical Causes of Well Ageing • Identification of Ageing Processes and Performance Assessment of Wells and Well Rehabilitations • Economics of Well Rehabilitation and Reconstruction • Mechanical Rehabilitation Techniques • Chemical Rehabilitation Techniques • Repair, Reconstruction, and Decommissioning of Wells • Practical Well Rehabilitation • Prevention • The Ten Dos and Don'ts of Water Well Rehabilitation • Appendices

No one has recorded when well digging started, but surely humans imitated elephants in digging holes in the sand to access cooler water that didn’t make the children sick. Eventually, humankind began to redesign, maintain, and repair the wells they constructed, but when wells became "commodities" in the twentieth century, this maintenance ethic was fogotten. Recapturing that ethic, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation is a guide to keeping well systems operating at peak capacity. The book focuses on how to prevent and forestall problems, and manage the problems with wells as they age. Examining the many challenges that come with maintaining well performance, the book provides a comprehensive yet readable state-of-the-art summary of performance maintenance, problem prevention, and rehabilitation or restoration practice with the goal of sustaining optimal performance over the long run. Rather than focusing on a certain aspect of well cleaning, or a particular technical approach, it covers the scope of maintenance and rehabilitation, from planning to evaluation testing. It also addresses the crucial subjects of preventive design, maintenance monitoring from electrical to biofouling, and evaluation testing. An exploration of the subject without a vendor or strong regional bias, the book is based on the authors’ extensive hands-on experience serving well-operating clientele. In addition to water supply wells, it addresses the problems and maintenance issues of monitoring, plume control, and other "environmental" wells. Compiling information from existing literature into a single source, and combining that information with experience, the book provides recommendations based on historical performance. Copiously illustrated with approximately ninety black and white photographs, figures, and a color insert, the book reflects the changes in the profession that have occurred during the past decade or so. These features and more make this the first resource to turn to when devising solutions for maintaining and improving well performance.

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.

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.
