Designation:D666110Standard Practice forField Collection of Organic Compounds from SurfacesUsing Wipe Sampling1This standard is issued under the fixed designation D6661;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 practice addresses sampling of organic compounds(i.e.,PCBs,dioxins,many pesticides and similar compounds)from smooth nonporous surfaces using a solvent-wetted wipesampling method.Samples are collected in a manner thatpermits the solvent extraction of the organic compound(s)ofinterest from the wipes and subsequent determination using alaboratory analysis technique such as gas chromatography witha suitable detector.This practice is,however,unsuitable for thecollection of volatile organic compounds.1.2 This practice should only be used to collect samples forthe determination of organic compound(s)on a loading basis(e.g.,mass per unit area).It cannot be used to collect samplesfor the determination of organic compounds on a concentrationbasis(e.g.,mass per unit mass).1.3 This wipe sampling practice is not recommended forcollecting samples of organic compounds from rough or poroussurfaces such as upholstery,carpeting,brick,rough concrete,ceiling tiles,and bare wood.It is also not intended for thecollection of dust samples(see Practice E1278)or sampling toestimating human exposure to contaminated surfaces.1.4 To ensure valid conclusions are reached,a sufficientnumber of samples must be obtained as directed by a samplingdesign(the number and location of samples including qualitycontrol samples)and a quality assurance/quality control plan.This practice does not address the sampling designs used toachieve the data quality objectives(see Practice D5792).1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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.2.Referenced Documents2.1 ASTM Standards:2D4687 Guide for General Planning of Waste SamplingD5681 Terminology for Waste and Waste ManagementD5792 Practice for Generation of Environmental Data Re-lated to Waste Management Activities:Development ofData Quality ObjectivesE1278 Guide for Radioactive Pathway Methodology forRelease of Sites Following Decommissioning(Withdrawn2005)33.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,refer to Terminology D5681.3.2 Definitions of Terms Specific to This Standard:3.2.1 wipe,nsorbent material(e.g.,cotton gauze)that isrubbed on a surface to collect a sample for chemical analysis.4.Summary of Practice4.1 A wipe sample is collected from a smooth nonporoussurface with a solvent-wetted wipe following a specifiedpattern of wiping to ensure complete coverage of an area ofspecified dimensions.The wipe is then extracted and analyzedto detect and quantify(at least semiquantitatively)the presenceof organic compounds on surfaces.5.Significance and Use5.1 Wipe sampling is typically used by persons involved inhazardous waste site investigations to characterize the arealextent and the level of contamination on walls,floors,equipment,etc.Wipe sampling is also used to determinecompliance with regulations.5.2 There are many factors that contribute to variation insampling results during wipe sampling including,the use ofdifferent pressures applied to the wipe,different kinds of wipes,1This practice is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.01.02 onSampling Techniques.Current edition approved Dec.1,2010.Published January 2011.Originallyapproved in 2001.Last previous edition approved in 2006 as D6661-01(2006).DOI:10.1520/D6661-10.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 different wiping patterns,the texture of the surface beingwiped,and perhaps even the duration of wiping.The signifi-cance of this practice is that it standardizes wiping proceduresto reduce sampling variability in the collection of samples fromsmooth,nonporous surfaces such as metal,glass,painted orsealed surfaces,tile,etc.,in and around buildings,and frompipes,tanks,decontaminated equipment,etc.6.Sampling Equipment and Supplies6.1 Sample Con
