Appendix A ' Groundwater Sampling Procedures And Logs Analyses of field blank water samples provide a cheep against contamination at the time of collection, dunng transportation, and within the laboratory The samples are collected by filling, the , sample bottles with deionized water Field blank water samples are submitted for each requested analysts One field duplicate sample was collected for this site samples Duplicate samples provide a check of consistency of laboratory analytical results The field duplicate samples are collected from a ' selected well along with the onginal sample and labeled in a manner that males the source of the sample unknown to the laboratory Trip blank samples were not collected since a mobile laboratory was used Laboratory QA/QC samples were analyzed to identify the precision and accuracy of the laboratory measurements Laboratory QA/QC samples consist of method blanks and matrix spike/matnx spike ' duplicates (MS/MSD) that are run daily as part of the Iaboratory's QA/QC plan The purpose of the method blank samples is to evaluate the potential for introduction (during laboratory sample ' handling) of an analyte into a sample extract, which is not present at detectable levels in the sample matnx The purpose of the MS/MSD samples is to evaluate the effects of the sample matnx on the measurement methodology A.3 SAMPLING PACKAGING AND SHIPPING Environmental were samples transported to the stationary (Curtis and Tompkins) analytical P P laboratory the following day after sample collection Samples were packaged and shipped according to EPA and Department of Transportation (DOT) regulations , A completed chain-of-custody form for each cooler was prepared and placed in a resealable plastic bag and taped to the inside of the cooler lid Coolers will be wrapped with strapping tape I at two locations to secure lids Numbered and signed custody seals will be placed on the outside of each cooler ' A.4 S AMPLE DOCUINIENIT kTION AND TRACKING A 4.1 Field rotes Documentation of observations and data acquired in the field will pro,,ide information on the acquisition of samples and pro%ide a penrianent record of field activities The observations and data v%ere recorded «ith indelible ink in a peniianenck bound weatherproof field book with , consecum el,. numbered pages and if applicable on field sampling data sheets The inforniation in the field book included the folio«inl as a minimum ' • Proleet name • Location of sample , • Sampler s signature USS Sremer Wo0aviarfl ClydeI1sHA1'SHAREDIPROXX41040100041SYYARD'MAINrYARDSA.DOC r
