The slug test is currently the most common method for the in situ estimation of hydraulic conductivity at sites of suspected groundwater contamination. However, inappropriate procedures in one or more phases of a slug test can introduce considerable error into the resulting parameter estimates. This book remedies this problem by answering virtually every question regarding the design, performance, and analysis of slug tests. This is the first book to provide detailed information on the practical aspects of the methodology of slug tests.
All major analysis methods are described in The Design, Performance, and Analysis of Slug Tests. Each analysis method is outlined in a step-by-step manner and illustrated with a field example. The major practical issues related to the field application of each technique are also discussed. This book will help the reader get more reliable parameter estimates from slug tests and increase the utility of slug test data.

"Excellent...a significant milestone in slug test technology and, for that matter, groundwater hydrology."
Herman Bouwer, USDA Water Conservation Laboratory
...the author has achieved his goal of providing a text to which a field investigator can refer for answers to questions concerning the design and analysis of slug test data. I can therefore commend this work to all groundwater practitioners and students with an interest in the design and performance of slug tests." -Joseph F. Botha, Institute for Groundwater Studies, University of the Free State Orange, Bloemfontein, South Africa
