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 [o <br />digestion and/or dilution of samples into analytical ranges. <br />Duality control results are reported "as analyzed" within <br />the instruments established calibration range. <br />c) The "Time Analyzed" in the OA 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 and sludge sanples are reported on a wet weight <br />basis (i.e. not corrected for percent moisture) unless otherwise <br />indicated. <br />BLANK DC SAMPLE (DENT IFICATiON <br />MB Method Blank <br />EB Extraction Blank <br />ICB Initial Calibration Blank <br />CCB Continuing Calibration Blank <br />SPIKE OC SAMPLE 1DENTIF]CATION <br />MS Method (Matrix) Spike <br />MSD Method (Matrix) Spike Duplicate <br />PDS Post-Digestion Spike <br />PSD Post-Digestion Spike Duplicate <br />SB Spike Blank <br />SBD Spike Blank Duplicate <br />REFERENCE STANDARD DC SAMPLE IOENT IFICAT ION <br />LCS Laboratory Control Standard <br />RS Reference Standard <br />ICV Initial Calibration Verification Standard <br />CCV Continuing Calibration Verification Standard <br />ISA/1$B ICP Interference Check Semple <br />ICL Initial CalibrationJLaboretory Control Sample <br />DSC Distilled Standard Check <br />CRI CRDL Low-Level ICP Standard <br />DUPLICATE DC SAMPLE IDENTIFICATION <br />MD 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 following codes: <br />SUBCONTRACT LABORATORY CODE <br />Core Laboratories - Anaheim, CA • AN <br />Core Laboratories - Casper, NY ' CA <br />Core Lahorator ies - Corpus Christi, TX • CC <br />Core Laboratories - Edison, NJ • ED <br />Page 4 <br />.....,w moo. ... -..,~o.~...„~p.o..,~,,._„~.~.~~..~...,.~,...em~.~.,..o..,..~,....,,.,.~.,.~b~4,A,wk.~.,_.,d.s.,~,.,p.~~~. _,~,~.~,~~.~..~e~~v. ~~,,,o... <br />
