NC = Not calculable due to value(s) lower <br />than the detection limit. <br />b) Data in the OA report may differ from final results due to <br />digestion and/or dilution of samples into analytical ranges. <br />Duality control results are reported "as analyzed" within <br />the instrunents established calibration range. <br />c) The "Time Analyzed" in the DA report refers to the start time of <br />the analytical batch which may not reflect the actual time of <br />each analysis. The "Date Analyzed" is the actual date of analysis. <br />d) Results for soil arxf sludge samples are reported on a wet weight <br />basis (i. e. not corrected for percent moisture) unless otherwise <br />indicated. <br />BLANK OC SAMPLE IDENTIFICATION <br />MB Me[hod Blank <br />EB Extraction Blank <br />ICB Initial Calibration Blank <br />CCB Continuing Calibration Blank <br />SPIKE OC SAMPLE IDENTIFICATION <br />MS Method (Matrix) Spike <br />NSD Method (Matrix) Spike Duplicate <br />PDS Pos[-Digestion Spike <br />SB Spike Blank <br />SBD Spike Blank Duplicate <br />REFERENCE STANDARD DC SAMPLE IDENTIFICATION <br />LCS Laboratory Control Standard <br />RS Reference Standard <br />ICV Initial Calibration Verification Standard <br />CCV Continuing Calibration Verification Standard <br />ISA/ISB ICP Interference Check Sanple <br />ICL Initial Calibration/Laboratory Control Sample <br />DSC Distilled Standard Check <br />DUPLICATE OC SAMPLE IDENTIFICATION <br />MD Xe[hod (Matrix) Duplicate <br />ED Extraction Duplicate <br />Analyses performed by a subcontract laboratory are indicated on the <br />analytical end/or quality control reports urxfer "Technician" using <br />the following codes: <br />SUBCONTRACT LABORATORY CODE <br />Core Laboratories - Anaheim, CA • AN <br />Core Laboratories - Lasper, NY • LA <br />Core Laboratories - Corpus Christi, T% • CC <br />Core Laboratories - Edison, NJ • ED <br />Core Laboratory es - Gulf States - Houston, TX • HE <br />Core Laboratories - Houston, T% • HP <br />Core Laboratories - Indianapolis, IN • IN <br />Page 2 <br />m..+nui~.~w..oad•....w•mm.~.e., nw ~.oa ..~~.i~io~.o ~.s..o~+der=.a.xv.m..a.n..n ows~. ~,~. n.,mn~«o.~..e. n. ~mrmon.orm <br />.w..a•v..~u.e.irw~~.~nm.umw~.w.um.iov.mo..,nw.~+~.b~~vw..m,..w..>mm.u m~m...,e.m.w we~...n...m m. o~m~wr. m.a . <br />.ya woowu ui.rt~.~oa.ir..~a renm..ea.«.w.nra.oo+.w enruw a.q~-wo... ur ~on.wiu e.~vm~n nreo dnun, •S°""' 7'40° °1.
