Manual of Field Hydrogeology

This field-oriented text/manual provides background information on the WHYs of field work as well as step-by-step procedures for the WHATs and HOWs of specific field tests. It provides students who already have a basic familiarity with introductory hydrogeology with hands-on practice in actual hydrogeologic field methods and activities. Outlines the steps and considerations in planning and conducting a field study - what to do before going to the field, upon arrival at the site, and before and after leaving the site, e.g.: - Information sources for planning. - What to do in the field. - Common sense health and safety guidelines. - Field equipment checklists. Introduces the most common projects assigned to entry-level hydrogeologists - e.g., leaking storage tank jobs, site assessments, monitoring well installation. Emphasizes groundwater, although one chapter introduces methods for surface water. Considers ground water contamination and urban hydrogeology. Explains methods and considerations for: - Describing soils and rocks. - Drilling boreholes. - Designing and installing wells. - Sampling and analyzing well water. Describes special field situations the hydrogeologic consultant is likely to encounter. Reviews the various geological, mathematical, and hand tools used in hydrogeology. Outlines step-by-step procedures for various field methods/tests - e.g., planning a pumping test, measuring discharge of a stream. - Provides convenient step-by-step summaries of each procedure. - Contains equipment checklists for each test. Discusses uses and limitations of the methods - so students can determine if a particular method applies to a given field situation. Shows how to make, read, and evaluate hydrogeologic maps, cross-sections, and flow nets from field data. Provides sample forms for recording field data - e.g., boring logs, well construction diagram, pumping test data. Contains solved sample problems - e.g., slug tests, stream discharge. Provides a variety of worked examples throughout: - Sample calculations and solved problems. - Field data collection forms and sample entries. - Examples of analytical processing of field data. Features many field projects that require teamwork.
