ABSTRACT
A hydrogeologic investigation can be no better than the quality of the field data and the investigator’s application of the scientific method (Fetter, 2001). It is essential that the field hydrogeologist keep a neat and complete field notebook. The field notebook should be a bound book of numbered waterproof pages. The data should be listed at the time it is collected. It should be written clearly in ink so that someone else can read it. It should contain carefully drawn sketches and photographs.
