Ground-water modeling has become an important methodology in support of the planning and decision-making processes involved in ground-water management. Ground-water models provide an analytical framework for obtaining an understanding of the mechanisms and controls of ground-water systems and the processes that influence their quality, especially those caused by human intervention in such systems. Increasingly, models are an integral part of water resources assessment, protection, and restoration studies, and provide essential and cost-effective support for planning and screening of alternative policies, regulations, and engineering designs affecting ground water. Many different ground-water modeling codes are available, each with their own capabilities, operational characteristics and limitations. Furthermore, each ground-water project has its own requirements with respect to modeling. Therefore, it is important that the most appropriate code is selected for a particular project. This is even more important for projects that require extensive modeling, or where costly decisions are based, in part, on the outcome of modeling-based analysis. Systematic and comprehensive description of project requirements and code features provides the necessary basis for efficient selection of a ground-water modeling code. This standard guide is intended to encourage comprehensive and consistent description of code capabilities and code requirements in the code selection process, as well as thorough documentation of the code selection process.1.1 This guide covers a systematic approach to the determination of the requirements for and the selection of computer codes used in a ground-water modeling project. Due to the complex nature of fluid flow and biotic and chemical transport in the subsurface, many different ground-water modeling codes exist, each having specific capabilities and limitations. Furthermore, a wide variety of situations may be encountered in projects where ground-water models are used. Determining the most appropriate code for a particular application requires a thorough analysis of the problem at hand and the required and available resources, as well as detailed description of the functionality of candidate codes. 1.2 The code selection process described in this guide consists of systematic analysis of project requirements and careful evaluation of the match between project needs and the capabilities of candidate codes. Insufficiently documented capabilities of candidate codes may require additional analysis of code functionality as part of the code selection process. Fig. 1 is provided to assist with the determination of project needs in terms of code capabilities, and, if necessary, to determine code capabilities. 1.3 This guide is one of a series of guides on ground-water modeling codes and their applications, such as Guides D5447, D5490, D5609, D5610, D5611, D5718, and D6025 . 1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action.

When sampling ground-water monitoring wells, it is very important to thoroughly document all field activities. Sufficient field data should be retained to allow one to reconstruct the procedures and conditions that may have affected the integrity of a sample. The field data generated are vital to the interpretation of the chemical data obtained from laboratory analyses of samples. Field data and observations may also be useful to analytical laboratory personnel.1.1 This guide covers what and how information should be recorded in the field when sampling a ground-water monitoring well. Following these recommendations will provide adequate documentation in most monitoring programs. In some situations, it may be necessary to record additional or different information, or both, to thoroughly document the sampling event. In other cases, it may not be necessary to record all of the information recommended in this guide. The level of documentation will be based on site-specific conditions and regulatory requirements.1.2 This guide is limited to written documentation of a ground-water sampling event. Other methods of documentation (that is, electronic and audiovisual) can be used but are not addressed in this guide. The specific activities addressed in this guide include documentation of static water level measurement, monitoring well purging, monitoring well sampling, field measurements, ground-water sample preparation, and ground-water sample shipment.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word "Standard" in the title of this document means only that the document has been approved through the ASTM consensus process.

Ground-water modeling has become an important methodology in support of the planning and decision-making processes involved in ground-water management. Ground-water models provide an analytical framework for obtaining an understanding of the mechanisms and controls of ground-water systems and the processes that influence their quality, especially those caused by human intervention in such systems. Increasingly, models are an integral part of water resources assessment, protection, and restoration studies and provide essential and cost-effective support for planning and screening of alternative policies, regulations, and engineering designs affecting ground-water (1). Successful ground-water management requires that decisions be based on the use of technically and scientifically sound methods for data collection, information processing, and interpretation, and that these methods are properly integrated. As computer codes are essential building blocks of modeling-based management, it is crucial that before such codes are used as planning and decision-making tools, their performance characteristics are established and their theoretical foundation, capabilities, and use documented. Good code documentation ensures scientific rigor and implementational quality in the development of a code (2). Complete and well-written documentation shortens the learning curve for new users, provides answers to questions from project managers, and supports efficient code selection. Well-structured and indexed documentation provides rapid answers for initiated users. This guide is intended to encourage comprehensive and consistent documentation of a ground-water modeling code. Earlier surveys of computer models and assessment of specific models indicate that the documents that are supposed to describe and explain these models and their use are lacking in detail, inconsistent in their contents, incomplete with respect to user instructions, inefficient with respect to indexing and structure, and often difficult to obtain (3). This still applies to the documentation of many of the ground-water modeling programs recently released or frequently used (4).1.1 This guide covers suggested components of the documentation of a ground-water modeling code. Documentation of a ground-water modeling code consists of textual and graphical information recorded during its design, development, and maintenance regarding its capabilities, development history, theoretical foundation, operation, and verification. It is the principal instrument for those involved in its development and use, such as code development and maintenance staff, network managers, code users, and project managers, to communicate regarding all aspects of the software. 1.2 This guide presents the major steps in preparing the documentation of a ground-water modeling code. It discusses the various documentation audiences and addresses the role of printed documentation versus documentation in electronic form. 1.3 This guide is one of a series of guides on ground-water modeling codes and their applications, such as Guides D5447, D5490, D5609, D5610, D5611, and D5718. 1.4 This guide is not intended to be all inclusive.

An essential requirement of hydrogeologists in evaluating the hydraulic properties of a segment of earth materials is to define and map hydrogeologic units, aquifers, and confining units, which are determined on the basis of relative permeability. Discussion of the hydrogeologic units is facilitated by individual designations (see Practices D5409, D5434, and D5474). Determinations of hydrogeologic units are based on indirect methods, knowledge of the geologic materials (geologic mapping, surface geophysical surveys, borehole geophysical logs, drill-cuttings and core descriptions, and so forth), and hydraulic testing (aquifer tests, laboratory permeability tests on core samples, and so forth). The physical properties of all rock units will change if traced laterally and vertically. The rock units are broken by unconformities and faults, which may or may not affect the flow of ground-water. The process of designating and naming aquifers and confining units, therefore, is a somewhat subjective undertaking, and, if not thoroughly documented, can lead to confusion. Guidelines for naming aquifers can help avoid some of the confusion and problems associated with hydrogeologic studies if the guidelines are straight forward to apply, flexible, and applicable to studies of a variety of scales from site-specific to regional. The guidelines that follow include discussions of the terminology of aquifer nomenclature, the definition of the hydrogeologic framework, the suggested procedures for naming aquifers, and examples of naming aquifers. These guidelines have resulted from numerous discussions on the subject of aquifer nomenclature among hydrogeologists. Although unanimous agreement on these proposals has not been achieved, the exercises provided an extremely useful purpose in creating additional thought and discussion.1.1 This guide covers 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 judgement. 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 eleven 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, alphanumeric 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).

Details required by the investigator to use fully the methods are found in the listed references. 1.2.1 The use fo maps to display water-quality data are a common technique to assist in the interpretation of the chemistry of water in aquifer, as the areally distributed values can be easily related to the physical locality by the investigator. 1.2.2 The distribution in an aquifer of chemical constituents from two water sources or of liquids of different densities may be difficult to illustrate explicitly on a two-dimensional map because of stratification in the third dimension. Also, the addition of a vertical cross section may be required (see 4.4). 1.3 Many graphic techniques have been developed by investigators to assist in summarizing and interpreting related data sets.

1.1 This guide covers methods that graphically display chemical analyses of multiple ground-water samples, discrete values and also those reduced to comprehensive summaries or parameters. Details required by the investigator to fully use the methods are found in the listed references. The methods included in this guide are many of the graphical procedures that were not discussed in two previous guides, Guides D 5738 and D 5754.Note 18212;The graphic methods in this guide apply to both raw and transformed data, for example, unaltered medians, maximums, and minimums and transformed means, square-roots, frequency distributions, and so forth. The methods are often computational intensive, requiring the use of a digital computer. Some graphical methods illustrate the results of the statistical analysis of a sample data set. For example, box plots are graphical portrayals of the maximum, minimum, median, 25th percentile, and 75th percentile of one variable, such as the chloride ion from a group of chemical analyses.Besides chemical components, other variables that may be plotted to show an interdependence with water chemistry include time, distance, and temperature.1.2 This guide on diagrams based on data analytical calculations is the third of several documents to inform the hydrologists and geochemists about traditional graphical methods for displaying ground-water chemical data.Note 28212;The initial guide described the category of water-analysis diagrams that use two-dimensional trilinear graphs to display, on a single diagram, the common chemical components from two or more analyses of natural ground water.1.2.1 The second guide described the category of water-analysis diagrams that use pattern and pictorial methods as a basis for displaying each of the individual chemical components determined from the analysis of a single sample of natural ground water.1.3 This guide presents a compilation of diagrams that allows for transformation of numerical data into visual, usable forms. It is not a guide to selection or use. That choice is program or project specific.1.4 Many graphic techniques have been developed by investigators to illustrate the results of the data analytical computations to assist in summarizing and interpreting related data sets. In this guide, selected graphical methods are illustrated using ground-water chemistry data.1.5 The basic or original format of each of the graphical techniques given in this guide has been modified in several ways, largely depending upon the data analytical techniques used by the investigators. Several minor modifications are mentioned, some significant revisions are discussed in more detail.1.6 Notations have been incorporated within many diagrams illustrated in this guide to assist the reader in understanding how the diagrams are constructed. These notations would not be required on a diagram designed for inclusion in a project document.Note 38212;Use of trade names in this guide is for identification purposes only and does not constitute endorsement by ASTM.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.
