(c) = Matrix spike recoveries were outside acceptable ranges due to matrix effects (d) = Relative Percent Difference (RPD) for duplicate analysis outside acceptance limits due to actual differences in the sample matrix. (e) = Thi limit listed for flammability indicates the upper limit for the test. Samples are not tested at temperatures above 140 Fahrenheit since only samples which wilt sustain ig�nition at temperatures below 140 are considered flammable (f) = Results for this hydrocarbon range did not match a typical hydrocarbon pattern. Results were quantified using a diesel standard, however, the hydrocarbon pattern did not match a diesel pattern. (g) = Results for this hydrocarbon range did not match a typical hydrocarbon pattern. Results were quantified wing a gasoline standard, however, the hydrocarbon pattern did not match a gasoline pattern (h) = High dilution due to matrix effects QC SAMPLE IDENTIFICATIONS SUBCONTRACTED LABORATORY LOCATIONS MS = Method Blank S8 = Storage Blank Core Laboratories Aurora, Colorado *AU RB = Reagent Blank MS = Matrix Spike Casper, Yyoaing *CA ICS = Initial Calibration Blank MSD = Matrix Spike Duplicate Corpus Christi, Texas *CC CCB - Continuing Calibration Blank MD = Matrix Duplicate Edison, New Jersey *ED CS = Calibration Standard BS = Blank Spike Houston, Texas (Env) *HE ICV = Initial Calibration SS = Surrogate Spike Houston, Texas (Pet) *HP Verification LCS = laboratory Control Indianapolis, Indiana *IN CCV = Continuing Calibration Standard Lake Charles, Louisiana *LC Verification RS - Reference Standard Lang Beach, California *LB Valparaiso, Indiana *VP Bakersfield, California *BK 1250 Gene Autry gay Autry Vay Anaheim, CA 92805 (714) 937-1094 /u/matt/logs n forms/footer.fors The ane'Ia f"Ats apnwne or nterpreratgne aantaned n th,e report are beSeO upon nt-1—end l-W-l su ed by the coxa for whq a estluSiva end 1nhi 11 uae two repot h-peen meaB The DWY1100 r wle pp�d inie,wom aW ewreeaea re+xeaent[he beet ladpritalr aCora Lebnratawe Care LeporetMae npraver rroMee rim wWrenlY a reWeeenlalgn esprees or impad of any type and expreaaly decevna ae.te es to tM PrpauGMtY Ofopar adereliIXH a poMrebleneae of eM aDas Cpel a 011wr maleral PrppenY yell —d 0 connection conn—th arrrn report ra Woad IX r..a upon tar enY reason w(rBtlOe'M TNI report ahem-t De reproduced I while or In pan wTr 'the vmltan avproyN of Dara I„abpreronea
