Designation:D517591(Reapproved 2011)Standard 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.1.Scope1.1 This test method(1,2,3)2is applicable to the determi-nation 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 section 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 as thestandard.The inch-pound units given in parentheses are forinformation only.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 and health practices and determine the applica-bility of regulatory limitations prior to use.For specific hazardstatements,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 May 1,2011.Published June 2011.Originallyapproved in 1991.Last previous edition approved in 2003 as D5175 91(2003).DOI:10.1520/D5175-91R11.2The boldface numbers in parentheses refer to a list of references at the end ofthis test method.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.Referenced Documents2.1 ASTM Standards:3D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD3534 Test Method for Polychlorinated Biphenyls(PCBs)in Water(Withdrawn 2003)4D3856 Guide for Management Systems in LaboratoriesEngaged in Analysis of WaterD4128 Guide for Identification and Quantitation of OrganicCompounds in Water by Combined Gas Chromatography3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.TABLE 1 Test Method Precision and BiasAas Functions of ConcentrationCompoundApplicable Co
