PollmriL Laboratories, Inc. 9773 171-hiu nrivo qt-h-t Rnrin- Cf1 RndR7 /RMl 33, Report Header Explanations Batch A distinct set of samples analyzed at a specific time Found Value of the QC Type of interest Limit Upper limit for RPD, in %. Lower Lower Recovery Limit, in % (except for LCSS, mg/Kg) LCL Lower Control Limit MDL Method Detection Limit. Same as Minimum Reporting Limit. Allows for instrument and annual fluctuations. PCN/SCN A number assigned to reagents/standards to trace to the manufacturer's certificate of analysis PQL Practical Quantitation Limit QC True Value of the Control Sample or the amount added to the Spike Rec Amount of the true value or spike added recovered, in % (except for LCSS, mg/Kg) RPD Relative Percent Difference, calculation used for Duplicate QC Types Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg) UCL Upper Control Limit Sample Value of the Sample of interest SURR Surrogate LFM Laboratory Fortified Matrix INTS Internal Standard LFMD Laboratory Fortified Matrix Duplicate DUP Sample Duplicate LRB Laboratory Reagent Blank LCSS Laboratory Control Sample - Soil MS/MSD Matrix Spike/Matrix Spike Duplicate LCSW Laboratory Control Sample - Water PBS Prep Blank - Soil LFB Laboratory Fortified Blank PBW Prep Blank - Water ?QC Sample Type Explanations Blanks Verifies that there is no or minimal contamination in the prep method procedure. Control Samples Verifies the accuracy of the method, including the prep procedure. Duplicates Verifies the precision of the instrument and/or method. Spikes/Fortified Matrix Determines sample matrix interferences, if any. (Qual) ,ACZ Qualifiers B Analyte detected in daily blank H Analysis exceeded method hold time. J Analyte concentration detected at a value between MDL and PQL. The associated value is an estimated quantity. R Poor spike recovery accepted because the other spike in the set fell within the given limits. T High Relative Percent Difference (RPD) accepted because sample concentrations are less than 10x the MDL. U The material was analyzed for, but was not detected above the level of the associated value. The associated value is either the sample quantitation limit or the sample detection limit. V High blank data accepted because sample concentration is 10 times higher than blank concentration W Poor recovery for Silver quality control is accepted because Silver often precipitates with Chloride. X Quality contreol sample is out of control. Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration. P Analyte concentration differs from second detector by more than 40%. E Analyte concentration is estimated due to result exceeding calibration range. M Analyte concentration is estimated due to matrix interferences. ?Method References (1) EPA 600/4-83-020. Methods for Chemical Analysis of Water and Wastes, March 1983. (2) EPA 600/4-90/020.
