1、Designation: D5474 93 (Reapproved 2012)Standard Guide forSelection of Data Elements for Groundwater Investigations1This standard is issued under the fixed designation D5474; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year

2、of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the selection of data elements for thedocumentation of groundwater sites. The data elements arede

3、scribed in four ASTM standards outlining information thatmay be collected at groundwater 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 1Agroundwater site is any source, locat

4、ion, or sampling stationcapable of producing water or hydrologic data from a natural stratum frombelow the surface of the earth. A source or facility can include a well,spring or seep, and drain or tunnel (nearly horizontal in orientation). Othersources, such as excavations, driven devices, bore hol

5、es, ponds, lakes, andsinkholes, that can be shown to be hydraulically connected to thegroundwater, are appropriate for the use intended.NOTE 2The four ASTM standards that describe the data elements forgroundwater are Practice D5254 and Guides D5408, D5409, and D5410.1.2 Systematic and consistent dat

6、a collection are necessaryfor the investigation of the availability and the protection orrestoration of groundwater 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, and the res

7、ources 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 these data. Th

8、is guide focuses onthose data elements that are gathered at the field-site locationand are used to assist in interpreting the hydrology of thegroundwater source and to meet regulatory requirements.Other analytical and quality assurance/quality control (QA/QC) considerations are addressed in other st

9、andards 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-bility of regulator

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 groundwater 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 andman

23、datory with all types of groundwater investigations and ispresented in 6.1.3.5. Significance and Use5.1 Data are gathered at groundwater sites for many pur-poses. Each purpose requires a different combination of dataelements. However, it is mandatory that every groundwater siteinclude a minimum set

24、of data elements to uniquely identifythat site by precisely locating with coordinates and politicalregimes, absolutely identifying the owner and data source, andclearly defining the basic site characteristics. This informationis described in Practice D5254.5.2 As a part of a groundwater project, eac

25、h site requiresadditional data elements, beyond the minimum set, to assist inthe interpretation of the local and areal hydrology. As anexample, for a hydrologic reconnaissance study of a ground-water basin, each well or spring site requires basic informationconcerning construction, water level, yiel

26、d, geology, and waterchemistry. Additional information is needed if the project is awaste facility investigation, usually to satisfy local, state, andfederal environmental regulations.6. Documentation6.1 Introduction:6.1.1 Four representative hydrologic projects with verydifferent objectives are pro

27、vided as examples to demonstratewhat data elements may be selected for a comprehensivegroundwater data file (Tables 1-4). When designing a ground-water data file, data elements from all four ASTM guidesshould be considered (see Note 2). Agencies or companies thatengage in widely diverse projects inv

28、olving groundwaterresources may require nearly all of the data elements describedin the four standards. Those organizations should design apermanent file system to their specifications that includes thesedata.NOTE 3A groundwater data file can be stored as various media suchas flat files in cabinets

29、or as digital records on a computer. No matterwhich system is used, the data elements retained are the same information.An advantage of using a computerized file is that the data base containingthe groundwater information can be easily displayed, duplicated, andtransferred to another computer.Advant

30、ages of paper flat files include lowcost, easy access without equipment, and transportability to field locationsand meetings.NOTE 4For the explanation of groundwater investigations in thisguide, the term “well” is used to mean any test or finished hole (that is,casing, screen, pump, etc.) that penet

31、rates the surface of the earth to accessthe groundwater source. These include drilled, bored, driven, and dugholes.6.1.2 Some agencies or companies may be very specializedin the objective of their projects and require only a finitenumber of data elements beyond the minimum data set.However, a limite

32、d data file may be expanded at a later date byadding additional data elements to satisfy the requirements ofmore extensive projects.6.1.3 The minimum set of data elements (see PracticeD5254) is mandatory to uniquely locate, identify, and describeeach individual groundwater site.
