1.1 This guide offers a series of options but does not specify a course of action. It should not be used as the sole criterion or basis of comparison and does not replace or relieve professional judgment.
1.2 This guide contains instructions and suggestions for authors of ground-water (hydrogeologic) reports in assigning appropriately derived and formatted aquifer nomenclature. Discussed are the water-bearing units that may require name identification, which are, ranked from largest to smallest, aquifer system, aquifer, and zone. Guidance is given on choosing the source of aquifer names, those are from lithologic terms, rock-stratigraphic units, and geographic names.
1.3 Included are examples of comparison charts and tables that can be used to define the hydrogeologic framework. Illustrations of 11 different hypothetical aquifer settings are presented to demonstrate the naming process.
1.4 Categories of items not suggested as a source of aquifer names are reviewed because, although they should be avoided, they occur in published documents. These categories are the following: time-stratigraphic names, relative position, alpha-numeric designations, depositional environment, depth of occurrence, acronyms, and hydrologic conditions.
1.5 Confining units are discussed with the suggestion that these units should not be named unless doing so clearly promotes an understanding of a particular aquifer system. Suggested sources of names for confining units correspond to those for aquifer names, which are lithologic terms, rock-stratigraphic units, and geographic names.
1.6 It is suggested that in reports that involve hydrogeology, the author should consider first not naming aquifers (see 6.2).
1.7 Format and expression styles are assessed along with the general cautions related to name selection of aquifers and confining units.
1.8 This guide is a modification of a previously published report (1).
