Designation:D540893(Reapproved 2010)1Standard Guide forSet of Data Elements to Describe a Groundwater Site;Part OneAdditional Identification Descriptors1This standard is issued under the fixed designation D5408;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year 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.1NOTEThe units statement in 1.4 was revised and inch-pound units were deleted throughout editorially in August2010.1.Scope1.1 This guide covers Part One of three guides to be used inconjunction with Practice D5254 that delineates the datadesirable to describe a groundwater data collection or samplingsite.This guide describes additional information beyond theminimum set of data elements that may be needed to identifya groundwater site.Part Two identifies physical descriptors,such as construction,for a site,while Part Three identifiesusage descriptors,such as monitoring,for an individualgroundwater site.NOTE1A groundwater site is defined as any source,location,orsampling station capable of producing water or hydrologic data from anatural stratum from below the surface of the earth.A source or facilitycan include a well,spring or seep,and drain or tunnel(nearly horizontalin orientation).Other sources,such as excavations,driven devices,boreholes,ponds,lakes,and sinkholes,that can be shown to be hydraulicallyconnected to the groundwater,are appropriate for the use intended.NOTE2Part Two(Guide D5409)includes individual site characteris-tic descriptors(7 data elements),construction descriptors(56 dataelements),lift descriptors(16 data elements),geologic descriptors(26 dataelements),hydraulic descriptors(20 data elements),and spring descriptors(11 data elements).Part Three(Guide D5410)includes monitoringdescriptors(77 data elements),irrigation descriptors(4 data elements),waste site descriptors(9 data elements),and decommissioning descriptors(8 data elements).For a list of descriptors in this guide,see Section 4.1.2 These data elements are described in terms used bygroundwater hydrologists.Standard references,such as theGlossary of Geology and various hydrogeologic professionalpublications,are used to determine these definitions.Many ofthe suggested elements and their representative codes are thoseestablished by the Water Resources Division of the U.S.Geological Survey and used in the National Water InformationSystems computerized data base(1-9).2NOTE3The purpose of this guide is to suggest data elements that canbe collected for groundwater sites.This does not uniquely imply acomputer data base,but rather data elements for entry into any type ofpermanent file.NOTE4Component and code lists given with some of the dataelements,for example“Format of Other Data,”are only suggestions.These lists can be modified,expanded,or reduced for the purpose intendedby the company or agency maintaining the groundwater data file.NOTE5Use of trade names in this guide is for identification purposesonly and does not constitute endorsement by ASTM.1.3 This guide includes the data elements desirable toidentify a groundwater site beyond those given in the“Mini-mum Set of Data Elements.”Some examples of the dataelements are map identification,permitting facts,and support-ing information.No single site will need every data element,for example,many groundwater sites do not need the dataelements described in the legal record group.Each record(group of related data elements)for a site has mandatory dataelements,such as the date for the ownership record.However,these elements are considered necessary only when that spe-cific record is gathered for the site.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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 regulatory limitations prior to use.1.6 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 aspects of this guide may be applicable in allcircumstances.This ASTM standard is not intended to repre-sent or replace the standard of care by which the adequacy ofa given professional service must be judged,nor should thisdocument be applied without consideration of a projects manyunique aspects.The word“Standard”in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.1This guide is under the jurisdiction of ASTM Committee D18 on Soil andRockand is the direct responsibility of Subcommittee D18.21 on
