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.

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.

Practical Handbook of Ground Water Monitoring covers the complete spectrum of state-of-the-science technology applied to investigations of ground water quality. The emphasis of the book is on the practical application of current technology, and minimum theory is discussed. The subject of ground water monitoring is covered in great detail, from the Federal regulations that require monitoring to the various direct and indirect methods of investigating the subsurface - to the analysis and interpretations of complex sets of water quality data. All aspects of ground water quality investigations, including site assessment techniques, health and safety considerations and equipment decontamination, are dealt with in a logical order that will allow the reader to follow along in the same thought progression as a field project. The experiences and expertise of more than 30 practicing scientists and engineers combine to make this book the most comprehensive reference compiled on the topic of ground water monitoring.

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.
