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 />Quality control results are reported "as analyzed" within <br />the instruments established calibration range. <br />c) The "time Analyzed" in the OA report refiers 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 and 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 IDENTI FI CAilON <br />MB Method Blank <br />EB Extraction Blank <br />ICB Initial Calibration Blank <br />CCB Continuing Calibration Blank <br />SP[KE DC SAMPLE IDENTIFICATION <br />MS Method (Matrix) Spike <br />MSD Method (Matrix} Spike Duplicate <br />PDS Pos t-Diges[i on Spike <br />PSD Pos t-Digesti on Spike Duplicate <br />SB Spike Blank <br />SBD Spike Blank Duplicate <br />REFERENCE STANDARD OC SAMPLE IDENTIFICATION <br />LCS Laboratory Control Standard <br />RS Reference Standard <br />]CV Initial Calibration Verlf ication Standard <br />CCV Continuing Calibration Verification Standard <br />ISA/ISB ICP Interference Check Sample <br />ICL Initial Calibration/Laboratory Control Saaple <br />DSC Distilled Standard Check <br />CRI CRDL Low-level ICP Standard <br />DUPLICATE OC SAMPLE IDENTIFICATION <br />ND Method (Matrix) Duplicate <br />ED Extraction Duplicate <br />SD Serial Dilution <br />Analyses performed by a subcontract laboratory are indicated on the <br />analytical and/or quality control reports under "Technician" using <br />the fof lowing codes: <br />SUBCONTRACT LABORATORY CODE <br />Core Laboratories - Anaheim, CA " AN <br />Core Laboratories - Casper, NY ~ CA <br />Core Laboratories - Corpus Christi, Tx • CC <br />Core Laboratories - Edison, NJ ' ED <br />Page 4 <br />..~~,,,~,.,,~~..,~. o.,,~ ~...co„~.M..~r..,.~,~.~. .,,..._. ......,m ~.~o.,..~... ..~~.,M,,.. ..,...,,..~~.~~~,,.,~,ti..~,...o.~,...._.~~~,,. o,.,,~~..~. ~o,. ,.~.,.... ,.,.. .o~...,.., <br /> <br />
