“…Wells: Introduction and Overview (Drage, 2022) provides a good discussion of drilling techniques used to install domestic wells. Ideally, pumping wells should include a screened or perforated interval that fully penetrates the aquifer and be of sufficient diameter to accept a pump that will produce the desired yield for the planned pumping test.…”

All groundwater investigations (including resource investigations, development of water supplies, and identification and remediation of contaminated sites) require deriving field-based values of basic hydrogeologic properties such as hydraulic conductivity, transmissivity and storativity. In the earlier Groundwater Project book “Hydrogeologic Properties of Earth Materials and Principles of Groundwater Flow” (Woessner and Poeter, 2020) groundwater principles and parameters were defined. Discussion of methods to determine parameters focused on laboratory methods and referenced field hydraulic testing methods but did not provide details on application. This book is a companion to that earlier work, as well as a standalone document that provides foundational methods used to generate field-scale representations of common hydraulic parameters. The authors present a conceptual view of how hydraulic testing methods such as the pumping tests, slug tests, and testing with packers are applied, as well as the advantages and limitations of the underpinning analytical solutions. They focus on methods addressing simplified confined, leaky confined and unconfined groundwater systems. The authors explain how curve-matching of field test data to analytical models is used to interpret test results. Software for analyzing hydraulic test data is briefly discussed, some of which include choices of several additional analytical models and one-button automated analysis, which can lead to misinterpretation of the data, so this book emphasizes basic concepts, principles, and methods. The main body of text along with many illustrations, examples, and exercises with solutions provide the reader with the information needed to correctly apply hydraulic testing and analytical methods.
