Case Narrative C <br /> Client: Union Pacific Railroad Job ID: 720-92832-1 <br /> Project/Site: UPRR-Stockton Monthly& Semi Annual <br /> Job ID: 720-92832-1 <br /> Laboratory: Eurofins TestAmerica, Pleasanton <br /> Narrative <br /> Job Narrative <br /> 720-92832-1 <br /> Comments <br /> No additional comments. <br /> Receipt <br /> The sample was received on 5/3/2019 9:10 AM;the sample arrived in good condition, properly preserved and,where required,on ice. The <br /> temperature of the cooler at receipt was 3.2°C. <br /> Receipt Exceptions <br /> The container amounts did not match the information listed on the Chain-of-Custody(COC): S40181 W#1, 9 containers listed on the COC, <br /> but recieved 12. <br /> The 3-40mL HCI vials received in one bubble bag,the bag had a completed label on it.The individual vials did not have completed <br /> sample labels. <br /> GC/MS VOA <br /> Method(s)624:The continuing calibration verification (CCV)associated with batch 440-546827 recovered above the upper control limit for <br /> Vinyl Chloride and 1,1-Dichloroethene.The samples associated with this CCV were non-detects for the affected analytes;therefore,the <br /> data have been reported. <br /> No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page. <br /> GC/MS Semi VOA <br /> Method(s)625:The continuing calibration verification (CCV)associated with batch 440-545900 recovered above the upper control limit for <br /> N-Nitrosodi-n-propylamine. The samples associated with this CCV were non-detects for the affected analytes;therefore, the data have <br /> been reported. <br /> Method(s)625:The RPD of the laboratory control sample(LCS)and laboratory control sample duplicate(LCSD)for batch preparation <br /> batch 440-545413 and analytical batch 440-545900 recovered outside control limits for the following analytes: Benzidine. <br /> Method(s)625:The laboratory control sample(LCS)for preparation batch 440-545413 and analytical batch 440-545900 recovered outside <br /> control limits for the following analytes: 2-Methylphenol,4-Methylphenol, 1,2-Diphenylhydrazine(as Azobenzene)and 2-Methylnaphthalene. <br /> These analytes were biased high in the LCS and were not detected in the associated samples;therefore,the data have been reported. <br /> No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page. <br /> Metals <br /> No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. <br /> General Chemistry <br /> No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. <br /> Organic Prep <br /> Method(s) 1664A:Analysis for Hexane Extractable Material(HEM)was performed for the following sample: S40181 W#1 (720-92832-1). <br /> Since the HEM result was below the reporting limit(RL),the result for Silica Gel Treated-Hexane Extractable Material (SGT-HEM)was <br /> reported as a non-detect. All HEM quality control criteria were met. <br /> Method(s)625: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate(MS/MSD)associated with <br /> preparation batch 440-545413. LCS was performed in duplicate to provide precision of data. <br /> No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. <br /> Eurofins TestAmerica, Pleasanton <br /> Page 4 of 31 5/20/2019 <br />
