1、Designation: D 5474 93 (Reapproved 2006)Standard Guide forSelection of Data Elements for Ground-WaterInvestigations1This standard is issued under the fixed designation D 5474; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea
2、r of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the selection of data elements for thedocumentation of ground-water sites. The data elements a
3、redescribed in four ASTM standards outlining information thatmay be collected at ground-water sites. Examples of specificinvestigations are given with the logic of why to selectindividual and combinations of data elements to meet therequirements of the studies.NOTE 1A ground-water site is any source
4、, location, or samplingstation capable of producing water or hydrologic data from a naturalstratum from below the surface of the earth. A source or facility caninclude a well, spring or seep, and drain or tunnel (nearly horizontal inorientation). Other sources, such as excavations, driven devices, b
5、oreholes, ponds, lakes, and sinkholes, that can be shown to be hydraulicallyconnected to the ground water, are appropriate for the use intended.NOTE 2The four ASTM standards that describe the data elements forground water are Practice D 5254 and Guides D 5408, D 5409, andD 5410.1.2 Systematic and co
6、nsistent data collection are necessaryfor the investigation of the availability and the protection orrestoration of ground-water resources. The level of detail,precision and bias, and the type of data that need to becollected depend on the objective of the study, the expectedcomplexity of the system
7、, and the resources available for theinvestigation. This guide presents ideas on what informationshould be collected for specific studies, why certain dataelements are mandatory, and the importance to current andfuture investigations of maintaining quality control on thecollection and retention of t
8、hese data. This guide focuses onthose data elements that are gathered at the field-site locationand are used to assist in interpreting the hydrology of theground-water source and to meet regulatory requirements.Other analytical and quality assurance/quality control (QA/QC) considerations are address
9、ed in other standards andbeyond the scope of this guide.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bilit
10、y of regulatory limitations prior to use.1.4 This guide offers an organized collection of informationor a series of options and does not recommend a specificcourse of action. This document cannot replace education orexperience and should be used in conjunction with professionaljudgment. Not all aspe
11、cts of this guide may be applicable in allcircumstances.

Thedata element is in the casing record record.3.1.5 recorddenotes a set of related data elements thatmay need to be repeated to fully describe a ground-water site.For exampl
19、e, a well that consists of several diameters of casingfrom the top end to the bottom will need more than one casingrecord record (the record includes data elements depth to top,depth to bottom, diameter, casing material, and casing thick-ness) to fully describe the construction of the well. However,
20、 ifonly a single size of casing is used in the well, the record isutilized once.3.1.6 record groupa set of related records. For example,the lift record group includes the lift record, power record, andstandby record. Some record groups consist of only one record,for example, the spring record group
21、includes only the springrecord.4. Summary of Guide4.1 This guide describes four representative categories ofinvestigations to demonstrate the logic of selecting data ele-ments for the documentation of ground-water data. Included inthis guide is a series of four tables that list the records (groupsof
22、 data elements) used for the examples. The tables cross-reference the sections in this guide where specific explanationsfor data elements are found. A complete list of the individualdata elements for each record is included in the text of thisguide. The minimum set of data elements is standard andma
23、ndatory with all types of ground-water investigations and ispresented in 6.1.3.5. Significance and Use5.1 Data are gathered at ground-water sites for many pur-poses. Each purpose requires a different combination of dataelements. However, it is mandatory that every ground-watersite include a minimum
24、set of data elements to uniquelyidentify that site by precisely locating with coordinates andpolitical regimes, absolutely identifying the owner and datasource, and clearly defining the basic site characteristics. Thisinformation is described in Practice D 5254.5.2 As a part of a ground-water projec
