"In recent years, the focus in hydrogeologic investigations has expanded to include aquifer sustainability as part of resource evaluations. While there are other books on the subject, Field Hydrogeology: A Guide for Site Investigations and Report Preparation provides the first integrated presentation of the American Society of Testing Materials (ASTM) standards, US Geological Survey (USGS), and US Environmental Protection Agency (EPA) field techniques. It also includes access to a Web site that contains software for designing aquifer tests and aquifer-recharge experiments. Written by an author with more than 50 years of experience in hydrology and geology, this reference treats the subject from a field standpoint. Useful as a field guide or textbook, it contains standard methods for planning and undertaking hydrogeologic investigations. It incorporates case studies, contains a glossary of field-hydrogeology technical terms, and provides a detailed list of ASTM standards and key hydrologic Web sites. The guide is based on ASTM standards as well as EPA and US Department of Interior field technical manuals. The text covers hydrogeologic fundamentals, conceptual models, planning an investigation, surface investigations, subsurface investigations, field inventory, stream flow measurements, water quality measurements, and report preparation. This revised and updated Second Edition also includes new material on the history of hydrogeology, field safety, aquifers, groundwater quality, hydrogeologic maps, and federal regulations. It gives students and seasoned professionals a vast array of clearly written descriptive materials and an extensive source of references available at their fingertips. Whats New in This Second Edition: New chapter on the history of hydrogeologyNew chapter on groundwater development and management, including US federal regulations and transboundary aquifersNew material on field safety, groundwater quality and testing, and construction of hydrogeologic cross section and maps New international case studiesNew THEIS computer model to design aquifer testsUpdated information on latest principles and techniques"--"Preface This document was prepared as a practical instruction guide for field hydrogeologists. It differs from other field guides in that the American Society for Testing and Materials (ASTM) and U.S. Geological Survey (USGS) techniques manuals and environmental protection manuals were used to prepare this guide and are referenced extensively. The guide was written in part to expose hydrogeologists, particularly those new to field investigations, to these detailed and useful standard operating procedures (SOPs). This second edition of Field Hydrogeology contains the following new sections: - history of hydrogeology - field safety - groundwater quality and testing the quality of groundwater - construction of hydrogeologic cross section and maps - federal laws to protect groundwater - transboundary aquifers - new THEIS computer model for designing aquifer tests This edition also has new case studies: Nubian aquifer in northern Africa, Mexico City, and the High Plains aquifer in the southwestern United States. Another addition to this field guide is a computer program to design the location of observation wells for aquifer tests"--
