Designation:D531492(Reapproved 2006)Standard Guide forSoil Gas Monitoring in the Vadose Zone1This standard is issued under the fixed designation D5314;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.1.Scope1.1 This guide covers information pertaining to a broadspectrum of practices and applications of soil atmospheresampling,including sample recovery and handling,sampleanalysis,data interpretation,and data reporting.This guide canincrease the awareness of soil gas monitoring practitionersconcerning important aspects of the behavior of the soil-water-gas-contaminant system in which this monitoring is performed,as well as inform them of the variety of available techniques ofeach aspect of the practice.Appropriate applications of soil gasmonitoring are identified,as are the purposes of the variousapplications.Emphasis is placed on soil gas contaminantdeterminations in certain application examples.1.2 This guide suggests a variety of approaches useful tosuccessfully monitor vadose zone contaminants with instruc-tions that offer direction to those who generate and use soil gasdata.1.3 This guide does not recommend a standard practice tofollow in all cases nor does it recommend definite courses ofaction.The success of any one soil gas monitoring methodol-ogy is strongly dependent upon the environment in which it isapplied.1.4 Concerns of practitioner liability or protection from orrelease from such liability,or both,are not addressed by thisguide.1.5 This guide is organized into the following sections andsubsections that address specific segments of the practice ofmonitoring soil gas:Section4Summary of Practice4.1Basic principles,including partitioning theory,migration andemplacement processes,and contaminant degradation4.7Summary Procedure5Significance and Use6Approach and Procedure6.1Sampling Methodology6.5Sample Handling and Transport6.6Analysis of Soil Gas Samples6.7Data Interpretation7Reporting1.6 This guide does not purport to set standard levels ofacceptable risk.Use of this guide for purposes of risk assess-ment is wholly the responsibility of the user.1.7 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.8 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.1.9 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.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD1356 Terminology Relating to Sampling and Analysis ofAtmospheresD1357 Practice for Planning the Sampling of the AmbientAtmosphereD1452 Practice for Soil Exploration and Sampling by AugerBoringsD1605 Practices for Sampling Atmospheres for Analysis of1This guide is under the jurisdiction of ASTM Committee D18 on Soil andRockand is the direct responsibility of Subcommittee D18.21 on Groundwater andVadose Zone Investigations.Current edition approved July 1,2006.Published July 2006.Originally approvedin 1992.Last previous edition approved in 2001 as D5314 92(2001).DOI:10.1520/D5314-92R06.2For 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 StatesNOTICE:This standard has either been superseded and replaced by a new version or withdrawn.Contact ASTM International(www.astm.org)for the latest information1Gases and Vapors(Withdrawn 1992)3D1914 Practice for Conversion Units and Factors Relating toSampling and Analysis of AtmospheresD2652 Terminology Relating to Activated CarbonD2820 Test Method for C Through C Hydrocarbons in theAtmosphere by Gas Chromatography(Withdrawn 1993)3D3249 Practice for General Ambient Air Analyzer Proce-duresD3416 Test Method for Total Hydrocarbons,Methane,andC
