Designation:D554919Standard Guide forContents of Geostatistical Site Investigation Report1This standard is issued under the fixed designation D5549;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.INTRODUCTIONGeostatistics is a framework for data analysis and estimation in media whose measurable attributesshow erratic spatial variability yet also possess a degree of spatial continuity imparted by the naturaland anthropogenic process operating therein.The soil,rock,and contained fluids encountered inenvironmental or geotechnical site investigations present such features and their sampled attributes aretherefore amenable to geostatistical treatment.This guide is concerned with the reporting of suchinvestigations.1.Scope1.1 This guide covers the contents required for a completereport of a geostatistical site investigation.Acomplete report isunderstood here to be one that contains all the informationnecessary to the understanding and evaluation of the geostatis-tical site investigation by other geostatisticians.1.2 This guide does not discuss the reporting of supplemen-tary information that may assist evaluation of the report.1.3 While geostatistical methods are used in many fields,this guide is primarily intended for the reporting of environ-mental and geotechnical applications.1.4 The basic geostatistical methods referred to in this guideare fully described in texts by David(1),2Journel andHuijbregts(2),Clark(3),and Isaaks and Srivastava(4).Olea(5)gives a thorough compilation of geostatistical terminologyas well as(6)a practical description of the subject for engineersand earth scientists.Chiles(7)and Goovaerts(8)providematerial on how to deal with spatial uncertainty and how to usegeostatistics for the evaluation of natural resources.1.5 Thisguidedoesnotdiscussthereportingofmultivariate,space-time,and other less-frequently used geo-statistical methods;however this is not intended to reflect anyjudgment as to the validity of these methods.1.6 Geostatistics is but one approach that can be used tounderstand and describe site conditions.Investigations shouldincorporate whatever supplementary knowledge of the site thatmay be available from other sources.As with classical statis-tical approaches,geostatistics is not intended to establishcause-and-effect relationships.1.7 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.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3D653 Terminology Relating to Soil,Rock,and ContainedFluids3.Terminology3.1 For definitions of common technical terms used in thisstandard,refer to Terminology D653.1This test method is under the jurisdiction ofASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.01 on Surface andSubsurface Characterization.Current edition approved May 1,2019.Published May 2019.Originallyapproved in 1988.Last previous edition approved in 1995 as D5549941,whichwas withdrawn December 2002 and reinstated in May 2019.DOI:10.1520/D7351-19.2The boldface numbers in parentheses refer to a list of references at the end ofthe text.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.2 Definitions of Terms Specific to This Standard:3.2.1 additivity,na mathematical property of a regional-iz
