Designation:D6914/D6914M16Standard Practice forSonic Drilling for Site Characterization and the Installationof Subsurface Monitoring Devices1This standard is issued under the fixed designation D6914/D6914M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers procedures for using sonic drillingmethods in the conducting of subsurface exploration for sitecharacterization and in the installation of subsurface monitor-ing devices.1.2 The use of the sonic drilling method for exploration andmonitoring-device installation may often involve preliminarysite research and safety planning,administration,and docu-mentation.1.3 Soil or Rock samples collected by sonic methods areclassed as group A or group B in accordance with PracticesD4220.Other sampling methods(Guide D6169)may be usedin conjunction with the sonic method to collect samples classedas group C and Group D.Other drilling methods are summa-rized in Guide D6286.1.4 UnitsThe values stated in either inch-pound units orSI units presented in brackets are to be regarded separately asstandard.The values stated in each system may not be exactequivalents;therefore,each system shall be used independentlyof the other.Combining values from the two systems mayresult in non-conformance with the standard.Reporting of testresults in units other than in-pound shall not be regarded asnonconformance with this practice.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this standard.1.6 This practice offers a set of instructions for performingone or more specific operations.It is a description of thepresent state-of-the-art practice of sonic drilling.It does notrecommend this method as a specific course of action.Thisdocument cannot replace education or experience and shouldbe used in conjunction with professional judgment.Not allaspects of this practice may be applicable in all circumstances.ThisASTM standard is not intended to represent or replace thestandard of care by which the adequacy of a given professionalservice must be judged,nor should this document be appliedwithout consideration of a projects many unique aspects.Theword“Standard”in the title of this document means only thatthe document has been approved through theASTM consensusprocess.1.6.1 This practice does not purport to comprehensivelyaddress all the methods and the issues associated with drillingpractices.Users should seek qualified professionals for deci-sions as to the proper equipment and methods that would bemost successful for their site investigation.Other methods maybe available for drilling and sampling of soil,and qualifiedprofessionals should have the flexibility to exercise judgmentas to possible alternatives not covered in this practice.Thispractice is current at the time of issue,but new alternativemethods may become available prior to revisions,therefore,users should consult manufacturers or sonic drilling servicesproviders prior to specifying program requirements.1.7 This practice does not purport to address all the safetyconcerns,if any,associated with its use and may involve use ofhazardous materials,equipment,and operations.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.For good safetypractice,consult applicable OSHA regulations and drillingsafety guides.2,3,42.Referenced Documents52.1 ASTM StandardsSoil Classification:D653 Terminology Relating to Soil,Rock,and ContainedFluidsD2113 Practice for Rock Core Drilling and Sampling ofRock for Site Exploration1This practice is under the jurisdiction of ASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.21 on Groundwater andVadose Zone Investigations.Current edition approved Nov.15,2016.Published December 2016.Originallyapproved in 2004.Last previous edition approved in 2010 as D691404(2010).DOI:10.1520/D6914_D6914M-16.2“Drilling Safety Guide,”National Drilling Association.3“Drillers Handbook,”Thomas C.Ruda and Peter Bosscher,National DrillingAssociation.4“Innovative Technology Summary Report,”April 1995,U.S.Department ofEnergy.5For 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.*A Summary of Changes section appears at the end of this standardCopyright 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
