Unless otherwise indicated, the data in this report are within the Limits of uncertainty as specified in the referenced method Quality control acceptance criteria are based either on Limits specified in the referenced method or on actual laboratory performance The date and time of analysis indicated on the QC report may not reflect the actual time of analysis for QC samples. Data reported in the QA report may be lower than sample data due to dilution of samples into the calibration range of the analysis Sample concentrations for solid samples are calculated on an as received (wet) basis unless otherwise indicated. Unless otherwise indicated, volatiles by gas chromatography (GC) are reported from a single column Volatiles analyses by GC on low Level soils are conducted at room temperature TCLP extractions are performed at sample amounts, approved by the State of California FLAGS, FOOTNOTES, AND ABBREVIATIONS (as needed) NA = Not analyzed H I. = Not Ignitable N/A = Not applicable S I. = Sustains Ignition ug/L = Micrograms per liter I(NS) = Ignites, but does not Sustain Ignition mg/L = Milligrams per liter RPD = Relative Percent Difference NO = Not detected at a value greater than the reporting limit NC = Not catcuLable due to values Lower than the detection limit (a) = Surrogate recoveries were outside acceptable ranges due to matrix effects (b) = Surrogate recoveries were not calculated due to dilution of the sample below the detectable range for the surrogate. (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) = The Limit Listed for flammability indicates the upper Limit for the test Samples are not tested at temperatures above 140 Fahrenheit since onty samples which wilt sustain ignition 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 using 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 M8 = Method Blank S8 = Storage Blank Core Laboratories: Aurora, Colorado *AU RS = Reagent Blank MS = Matrix Spike Casper, Wyoming *CA ICS = Initial Calibration Stank 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 ICY = Initial Calibration SS = Surrogate Spike Houston, Texas (Pet) *HP verification LCS = Laboratory Control Indianapolis, Indiana *IM CCV = Continuing Calibration Standard Lake Charles, Louisiana *LC Verification RS = Reference Standard Long Beach, California *LS Valparaiso, Indiana *VP Bakersfield, California *BK 1250 Gene Autry Way Autry Way Anaheim, CA 92805 (714) 937-1094 /u/matt/logs n_forms/footer.form ��m�a o 1,
