Designation:D517591(Reapproved 2017)1Standard Test Method forOrganohalide Pesticides and Polychlorinated Biphenyls inWater by Microextraction and Gas Chromatography1This standard is issued under the fixed designation D5175;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.1NOTEWarning notes were editorially updated throughout in December 2017.1.Scope1.1 This test method(1-3)2is applicable to the determina-tion of the following analytes in finished drinking water,drinking water during intermediate stages of treatment,and theraw source water:AnalyteChemical Abstract ServiceRegistry NumberAAlachlor5972-60-8Aldrin309-00-2Chlordane57-74-9Dieldrin60-57-1Endrin72-20-8Heptachlor76-44-8Heptachlor Epoxide1024-57-3Hexachlorobenzene118-74-1Lindane58-89-9Methoxychlor72-43-5Toxaphene8001-35-2AroclorB101612674-11-2AroclorB122111104-28-2AroclorB123211141-16-5AroclorB124253469-21-9AroclorB124812672-29-6AroclorB125411097-69-1AroclorB126011096-82-5ANumbering system of CAS Registry Services,P.O.Box 3343,Columbus,OH43210-0334.BAroclor is a registered trademark of Monsanto Co.1.2 Detection limits for most test method analytes are lessthan 1 g/L.Actual detection limits are highly dependent onthe characteristics of the sample matrix and the gas chroma-tography system.Table 1 contains the applicable concentrationrange for the precision and bias statements.Only Aroclor 1016and 1254 were included in the interlaboratory test used toderive the precision and bias statements.Data for other PCBproducts are likely to be similar.1.3 Chlordane,toxaphene,and Aroclor products(polychlo-rinated biphenyls)are multicomponent materials.Precision andbias statements reflect recovery of these materials dosed intowater samples.The precision and bias statements may notapply to environmentally altered materials or to samplescontaining complex mixtures of polychlorinated biphenyls(PCBs)and organochlorine pesticides.1.4 For compounds other than those listed in 1.1 or for othersample sources,the analyst must demonstrate the applicabilityof this test method by collecting precision and bias data onspiked samples(groundwater,tap water)(4)and providequalitative confirmation of results by gas chromatography/mass spectrometry(GC/MS)(5)or by GC analysis usingdissimilar columns.1.5 This test method is restricted to use by or under thesupervision of analysts experienced in the use of GC and in theinterpretation of gas chromatograms.Each analyst must dem-onstrate the ability to generate acceptable results using theprocedure described in Section 13.1.6 Analytes that are not separated chromatographically,(analytes that have very similar retention times)cannot beindividually identified and measured in the same calibrationmixture or water sample unless an alternative technique foridentification and quantitation exists(see 13.4).1.7 When this test method is used to analyze unfamiliarsamples for any or all of the analytes listed in 1.1,analyteidentifications and concentrations should be confirmed by atleast one additional technique.1.8 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.9 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.For specific hazard statements,see Section 9.1This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.06 on Methods forAnalysis forOrganic Substances in Water.Current edition approved Dec.15,2017.Published January 2018.Originallyapproved in 1991.Last previous edition approved in 2011 as D5175 91(2011).DOI:10.1520/D5175-91R17E01.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.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 1.10 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
