The Design, Performance, and Analysis of Slug Tests

The slug test can provide valuable information for hydrogeologic investigations ranging from assessments of sites of groundwater contamination to the monitoring of well deterioration through time. Inappropriate procedures in one or more phases of a test program, however, can introduce considerable error into the resulting parameter estimates. The Design, Performance, and Analysis of Slug Tests, Second Edition remedies that problem by explaining virtually all there is to know regarding the design, performance, and analysis of slug tests. The first edition has become the standard reference for all aspects of slug tests; this revised edition updates the earlier material and expands the topical coverage with new developments that have come to the fore in the intervening years between editions. Features: Describes and demonstrates the eight key steps for the performance and analysis of slug tests Presents new methods for the analysis of tests in unconfined aquifers and in highly permeable settings Expands topical coverage of LNAPL baildown tests and slug tests in small diameter wells Includes numerous flow charts that illustrate easy-to-use strategies for selection of analysis methods, and field examples demonstrate how each method should be used to get the most out of test data Offers straightforward practical guidelines that summarize the major points of each chapter Written for practicing groundwater consultants and engineers, The Design, Performance, and Analysis of Slug Tests, Second Edition will enable readers to get more reliable information from slug tests and increase the utility of this widely-used field method.

Jim Butler is a senior scientist with the Geohydrology Section of the Kansas Geological Survey at the University of Kansas. He holds a B.S. in Geology from the College of William and Mary, and a M.S. and Ph.D. in Applied Hydrogeology from Stanford University. His primary research interests include high-resolution subsurface characterization, well responses to natural and anthropogenic stresses, and assessment of aquifers that support irrigated agriculture. Jim was the 2007 Darcy Distinguished Lecturer of the National Ground Water Association and the 2009 recipient of the Pioneers in Groundwater Award of the Environmental and Water Resources Institute of the American Society of Civil Engineers. He has served on the editorial board of five technical journals, has taught continuing education workshops and short courses on four continents, and has held visiting researcher positions at Stanford University, Universitat Politècnica de València, the University of Tübingen, Sandia National Laboratory, and the Institute of Geology of the State Seismological Bureau.
