Hydrogeological Conceptual Site Models

Neven Kresic, PhD, is a hydrogeology practice leader at AMEC Environment and Infrastructure, Inc., an international engineering and consulting firm. He is a professional geologist and professional hydrogeologist working for a variety of national and international clients, including industry, mining, water utilities, government agencies, and environmental law firms. He serves on the management committee of the Groundwater Management and Restoration Specialty Group of the International Water Association, co-chairs the karst commission of the International Association of Hydrogeologists, and is a past vice president for international affairs of the American Institute of Hydrology. Alex Mikszewskiis a licensed professional environmental engineer in Massachusetts, where he works for Woodard & Curran, Inc. He holds a bachelor’s degree in civil and environmental engineering from Cornell University and a master’s in environmental engineering and science from The Johns Hopkins University. As a consultant, he has developed variably saturated groundwater models for clients in the public and private sectors and conducted geostatistical evaluations of hydrogeological data for remediation and water resources applications. Alex has hands-on experience with a variety of remedial technologies, including in situ chemical oxidation, soil vapor extraction, in situ thermal remediation, monitored natural attenuation, and pump and treat.

"...unique in that it combines new computer techniques and classical exploration methods …this book by Neven Kresic and Alex Mikszewski fills the gap in hydrogeological literature by identifying and explaining essential techniques. Real life examples are given in each chapter. This visually powerful text covers a significant amount of material and contains hundreds of colored figures and illustrations…"—Environ Earth Sci, April 2014"…provides a roadmap with over 500 color illustrations as examples to expertly prepare accurate, comprehensive conceptual site models and how best to convey the associated hydrogeological data…The most useful part of this book are hundreds of versions of maps, cross-sections, and other subsurface imagery which provides a virtual atlas of effective conceptual graphics and visualization tools for use in regulatory discussions, policy evaluations, public meetings or litigation support roles."—The Professional Geologist, 2014"… serves to provide a clear understanding of the problem through technically viable solutions and conclusions, and in this way to better communicate results and recommendations to both technical and nontechnical professionals. It also assists clients in making informed decisions."—Bashir A. Memon "[The authors] commit to not only providing strong technical discussion but also giving perspective on the utility of the data and how it applies to the world we live and work in. The subject matter is written with a strong technical and theoretical foundation that is described in terms for the general remedial practitioner without diluting the scientific credibility."—Michael Skinner, Michael J. Skinner Consulting, LLC, New Jersey, USA"The authors’ approach and selection of topics is excellent, as they draw important connections between groundwater quality and supply, surface water hydrology, and GIS, and discuss tools and implications associated with interpolative and simulation based conceptualizations. ... The authors cover a tremendous amount of material, and merge old with the new in an easy-to-understand and well organized manner."—Mark Kram, Groundswell Technologies, Inc., California, USA"The strength of this book is the focus on the development and presentation of the conceptual site model (CSM). Too many times in remediation the CSM is largely neglected and therefore the remediation can be inadequate in meeting the client’s expectations or does not meet the site remedial goals. ... This book will help the client and their consultant understand what is needed to ensure that the site conditions are understood and therefore the remedial strategy and design is appropriate."—Mike Marley, XDD, New Hampshire, USA"The authors have applied a logical and systematic approach, flowing smoothly from basic explanations ... to very specific instructions on how to visualize and model nature. This is one of the very first books of this type, quite modern in combining new computer techniques and classical exploration methods."—Zoran Stevanovic, Professor, Chair of Hydrogeology Department, Faculty of Mining & Geology, University of Belgrade, Serbia"The purpose of the book is not to become, or even replace one of the standard hydrogeological textbooks. It is to fill the gap between theory and practice; to identify and explain key concepts that the professional hydrogeologist, the client or the regulator face in their everyday practice… Overall the authors deliver on their promises, and I am confident that most practitioners in geotechnical engineering will greatly benefit from reading this book."––New Zealand Geomechanics News, December 2013
