Book Description
FROM THE PREFACE The approach of this book is "how-to-do and hands-on." Its purpose is to provide clear, step-by-step instruction in many of the fundamental methods of hydrogeologic investigation. These methods include both 1) the traditional techniques of data analysis, such as mathematical computation by electronic calculator and construction of graphs by hand-plotting, and 2) microcomputer techniques employing electronic spreadsheets, graphing and gridding and contouring software. The microcomputer methods employ commercial software such as Lotus 1-2-3. Microsoft Excel, Quattro-Pro, Golden Software's Grapher and Surfer, and Geraghty and Miller's AQTESOLV. Although familiarity with any of the applications is helpful, the instructions in this manual assume no prior experience with them. Basic Hydrogeologic Methods is divided into three sections: Groundwater Occurrence and Movement, Groundwater Investigations, and Well and Aquifer Hydraulics. Each section begins with a brief summary of relevant terminology and principles. This introductory chapter is followed by a case study, which may be employed to provide a practical context for the hydrogeological methods that are described in subsequent chapters. Most of the methodological exercises culminate in an analytical product, such as data table, graph, contour map, etc., which readily serve as a focus for problem-solving activities, classroom discussions, and investigative reports. Many of the exercises present at least two investigative methods for accomplishing a particular hydrogeologic task. For example, time-drawdown graphs may be produced by a hand-plotting method or by a microcomputer method. For the professional scientist, the choice of a particular method might depend on such factors as the time available to carry out the task, the degree of accuracy required, or the availability of assessory equipment and materials. The introductory student can work through a more fundamental method (e.g., hand-plotting) before advancing to a microcomputer method (e.g., spreadsheet and graphing).

Book Description
Tremendous improvements in ground-water sampling methodologies and analytical technologies have made it possible to collect and analyze truly representative samples to detect increasingly lower levels of contaminants-now in the sub-parts-per-billion range. Though these new methods produce more accurate and precise data and are less expensive, many

Book Description
A thorough, up-to-date guide to groundwater science and technology Our understanding of the occurrence and movement of water under the Earth's surface is constantly advancing, with new models, improved drilling equipment, new research, and refined techniques for managing this vital resource. Responding to these tremendous changes, David Todd and new coauthor Larry Mays equip readers with a thorough and up-to-date grounding in the science and technology of groundwater hydrology. Groundwater Hydrology, Third Edition offers a unified presentation of the field, treating fundamental principles, methods, and problems as a whole. With this new edition, you'll be able to stay current with recent developments in groundwater hydrology, learn modern modeling methods, and apply what you've learned to realistic situations. Highlights of the Third Edition * New example problems and case studies, as well as problem sets at the end of each chapter. * A special focus on modern groundwater modeling methods, including a new chapter on modeling (Chapter 9), which describes the U. S. Geological Survey MODFLOW model. * Over 300 new figures and photos. * Both SI and U.S. customary units in the example problems. * Expanded coverage of groundwater contamination by chemicals. * New references at the end of each chapter, which provide sources for research and graduate study. Student and instructor resources for this text are available on the book's website at www.wiley.com/college/todd.
