Designation:D6564/D6564M17Standard Guide forField Filtration of Groundwater Samples1This standard is issued under the fixed designation D6564/D6564M;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 guide covers methods for field filtration of ground-water samples collected from groundwater monitoring wells,excluding samples that contain non-aqueous phase liquids(either Dense Non-Aqueous Phase Liquids(DNAPLs)or LightNon-Aqueous Phase Liquids(LNAPLs).Methods of fieldfiltration described herein could also be applied to samplescollected from wells used for other purposes.Laboratoryfiltration methods are not described in this guide.1.2 This guide provides procedures available for field filtra-tion of groundwater samples.The need for sample filtration forspecific analytes should be defined prior to the sampling eventand documented in the site-specific sampling and analysis planin accordance with Guide D5903.The decision should be madeon a parameter-specific basis with consideration of the dataquality objectives of the sampling program,any applicableregulatory agency guidelines,and analytical method require-ments.1.3 This guide offers an organized collection of informationor a series of options and does not recommend a specific courseof action.This guide cannot replace education or experienceand should be used in conjunction with professional judgment.Not all aspects of this guide may be applicable in all circum-stances.This guide is not intended to represent or replace thestandard of care by which the adequacy of a given professionalservice to be judged,nor should this guide be applied withoutconsideration of the many unique aspects of a project.Theword“Standard”in the title of this guide means only that theguide has been approved through the ASTM consensus pro-cess.1.4 UnitsThe values stated in either SI Units or inch-pound units given 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.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 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:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD5088 Practice for Decontamination of Field EquipmentUsed at Waste SitesD5092 Practice for Design and Installation of GroundwaterMonitoring WellsD5903 Guide for Planning and Preparing for a GroundwaterSampling EventD6089 Guide for Documenting a Groundwater SamplingEvent3.Terminology3.1 DefinitionsFor definitions of common technical termsin this standard,refer to Terminology D653.3.2 Definitions of Terms Specific to This Standard:3.2.1 filter,vin groundwater sampling,to pass a fluidcontaining particles through a filter medium whereby particlesare separated from the fluid.3.2.2 filter,nin groundwater sampling,a device for car-rying out filtration which consists of the combination of thefilter medium and suitable hardware for constraining andsupporting it in the path of the fluid.3.2.3 filter medium,nin groundwater sampling,the per-meable material used for a filter that separates particles from afluid passing through it.1This guide is under the jurisdiction ofASTM Committee D18 on Soil and Rockand is the direct responsibility of Subcommittee D18.21 on Groundwater andVadose Zone Investigations.Current edition approved Dec.15,2017.Published January 2018.Originallyapproved in 2000.Last previous edition approved in 2012 as D6564 00(2012)1.DOI:10.1520/D6564_D6564M-17.2For 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.*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 principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides
